If the repair is critical or structural, an epoxy resin should be considered. We frequently get asked about the difference between epoxy resin and polyester resin. They also harden differently. UV Stability: Polyurethanes exhibit excellent UV-resistance. Polyester and polyurethane resins are the most commonly used casting material available. Reaction of polyepoxides … To cover wood, a laminate using epoxy resin and 10 oz, cloth will yield a much better job than 10 oz. A complete coating system is only as good as its initial bond to the concrete substrate. Cons • There are, some particular usage method of epoxy resin, it can be highly dangerous if not used correctly. Polyester resin is most commonly used in the construction of molded reinforced fiber and composite products, so its mechanical properties … All rights reserved. There are some differences between polyurethane and epoxy. Epoxy and polyurethane are great for protecting your floor against stains, damage, chemicals, oils, and wear. Epoxy resin makes a strong and durable tabletop. Available here, 1.’Epoxy’ By Dzhang2680 – Own work, (CC BY-SA 3.0) via Commons Wikimedia  They cannot be used as a complete system in itself. Epoxy injection is performed through surface mounted ports. Like epoxy, it is a 2-part component that mixes resin with a catalyst to cause the curing reaction that makes the material hard. In summary – Epoxy vs Polyurethane. Flexible and elastic properties go to both of these options and each substance is used in the automotive industry, in the manufacture of certain parts. One of our all-time most popular posts on Allthingsflooring.com is “Epoxy vs Polyurethane – which will you choose”.As this has proved to be such an in-demand topic, we thought we’d follow up with a post that looks into these two resin chemistries in a bit more depth. Build/Thickness: Epoxy build coats are typically installed at 8 to 15 mils per application. The unit for this measurement is “mol/kg”. That being said, there might be a few dilemmas and … “What’s the difference with epoxy vs polyurethane coatings?”. Or else, epoxy resins can react with some other compounds such as; These are co-reactants. If epoxy is stronger, how is pu more scratch resistant? Polyurethanes are the “icing on the cake”. • Damaging or getting a crack on it is almost impossible, this is because of the high durability of epoxy resin. It’s not a matter of choosing one over the other, but a matter of utilizing both to achieve the desired result: Epoxy primers for bonding the system to concrete, epoxy build coat(s) for total system build/thickness, and polyurethane topcoats for enhanced physical performance, chemical-resistance, safety and aesthetics. Polyurethane is a polymer material that has urethane linkages. Polyurethane coatings perform very similar to Polyaspartics but they take longer time to cure (at least 24 hours) and need to be applied very thin (4 to 6 mils per coat) Polyurethane coatings are used mostly top coats over Epoxy coatings. These monomers combine with each other to form a polymer. It can be overwhelming at first. We frequently get asked about the difference between epoxy resin and polyester resin. The urethane linkage forms when the –N=C=O group of isocyanate react with the –OH groups of alcohol to form a urethane linkage (-NH-C(=O)-O). Polyurethane may be the most durable resin of them all and that means you won’t need to do as much maintenance when you choose polyurethane. Polyurethanes can withstand high temperatures. These epoxies are designed by having the curing agent with a small amount of epoxy resin. Epoxy and Polyurethane resin floors are the two most common types of floor coatings. • In some cases, Epoxy is even better than polyurethane. Urethane is composed of organic, or carbon-based, links that react with a … They cannot be used as a complete system in itself. If an uncured PU floor is attacked by water or condensation you may get this catastrophic results (like in the picture below). Polyurethane (or urethane), used for foundation crack repair applications, while not necessarily a 2 component blend, can have 2 components; the polyurethane resin and an activator, or accelerator. If the repair is critical or structural, an epoxy resin should be considered. Because casting resins are typically capable of thicker pours, they dissipate heat (exotherm) much slower than coating epoxy. Epoxy resin countertops are a mixture of resin, silica, a hardener, and filler, which are molded and oven cured as a solid slab. Epoxies are a type of polyurethanes. Comparison of the characteristics of epoxy and polyurethane Epoxy and polyurethane are referred to as resins; for the most part, both are two component formulations. It’s not as strong as epoxy but there are some occasions when it might do a better job. Side by Side Comparison – Epoxy vs Polyurethane in Tabular Form When choosing a resin to coat a concrete floor, companies want to make the best choice, which is usually reduced to either epoxy vs polyurethane. Epoxy’s quality of being an excellent insulator makes it possible to be used in the electrical industry. Polyurethane vs Rubber. Can I use any kind of paint in the mold before casting as long as it is completely dry before the cast? Epoxy is made from epoxide and polyamine as a resin and hardener blend. “What Are Epoxy Resins?” ThoughtCo, ThoughtCo. Polyurethane is a polymer material that has urethane linkages (carbamate linkages). “Polyurethanes.” The Essential Chemical Industry Online. Polyurethanes "dry" in a fairly short time, but resins "cure" instead of drying and that takes at least 24 hrs. 6. In the application point of view, the main difference between epoxy and polyurethane is that the epoxy resins can resist moderate temperatures while the polyurethanes can withstand high temperatures. • Epoxy resin forms stronger bonds when it comes to gluing two pieces together and has better adhesive properties with surfaces like wood, metal or concrete. Cure time for PU is much longer than PMMA. A layer of resin is applied to the floor and then cured – the process whereby the resin hardens. Dear Katherine you seem to know a lot about resins. Epoxy Vs. Polyurethane: Which is the Best Resin for Your Driveway? Often, people say “resin” without specifying which resin. There are a number of different epoxy floor coatings on the market today, with costs that are all over the map. In general, epoxy resins offer limited resistance to the organic acids that are found in large quantity of food and drink produce, whereas polyurethane systems boast unrivalled resistance to corrosion, inorganic, alkalis, organic alkalis and solvents. Sawdust will take up ‘water stains’ when mixed with resin, unless it is sealed first. • The next use of Epoxy is in the production purpose of various electronic things such as insulators, generators, transformers, etc. Polyurea is a subgroup of polyurethane. For example, the user can add an inhibitor to the resin to increase the so-called pot life, i.e., the processing time. Polyurethane injections can take anywhere between 15 to 45 minutes to cure, whereas epoxy options need 3 to 4 hours to fully cure at room temperature. You want a floor that is strong, like your business, and worry-free. 2. 1. For concrete floor coating applications, the most durable, longest-lasting coating systems usually include the use of both epoxy and polyurethane. It's said that one pouring of epoxy resin is "equal to 60 coats of polyurethane" in thickness, but it isn't necessary to use a resin just to get a high gloss effect. • Epoxy resin forms stronger bonds when it comes to gluing two pieces together and has better adhesive properties with surfaces like wood, metal or concrete. Polyurethane coatings are only about 2 or 3 mils thick and just about 60% or 70% solids, depending on the manufacturing company you get the coating from. Polyurethane resin, on the other hand, is up to 50 times more expansive than epoxy resin, making it far more resistant to cracking and therefore suitable for indoor or outdoor use. Epoxy and polyurethane are great for protecting your floor against stains, damage, chemicals, oils, and wear. Polyurethane will not bond as wide a range of materials as epoxy resin will but in the case of fiber, wood, leather, etc. What is Epoxy? mat and 10 oz. 7875 Bliss ParkwayNorth Ridgeville, Ohio 44039, info@protectpoly.comWe reply within 24 hours, Sean Walsh is the Marketing & Product Development Manager of Protective Industrial Polymers, a company that manufactures high-performance resinous floor coatings for industrial manufacturing environments, which has a keen focus on developing unique solutions for managing electrostatic, microbial, chemical, explosion and safety risk concerns. Video of the Day Volume 0% Finishes: Polyurethane finishes can range from satin to semi-gloss to high-gloss. 3. “For a general industrial or commercial application, the vast majority of the time I would recommend, at minimum, a three coat system consisting of an epoxy primer, an epoxy build-coat and a polyurethane topcoat,” I respond. With so many options available, it's difficult to decide what's best for your facility. It is a form of polyurethane. Epoxy Benefits Epoxies come in a variet If you’re contemplating some major build or repair projects involving fiberglass this summer, then you are probably trying to decide whether it is worth the added expense of using epoxy instead of polyester resin. Polyester resin is excellent for fiberglass lay-up — building a boat, for example. 2. They are also not as abrasion and chemical-resistant as polyurethanes. When it comes to epoxy vs polyurethane coatings, the important take-away is to realize that both product technologies work well in conjunction with each other to produce a durable, long-lasting flooring solution. Epoxy or epoxy resin is a class of polymer material that consists of epoxy functional groups. Summary. There are similarities between these substances, but their differences are more apparent and each industry seems to have its own preference. it creates a perfectly serviceable bond and one which is likely to be clear in appearance as well as strong. It is formed when isocyanates react with water or polyetheramines to create a urea linkage. Increased Impact and Abrasion Resistance: Polyurethanes exhibit excellent impact and abrasion resistance, providing up to four times longer life than uncoated epoxy floors. Epoxy resins can react with each other via catalytic homopolymerization and form cross-links between them. Why is Planet Earth Your True Friend for ESD Grounding? cloth and polyester resin. Proper Floor Cleaning and Maintenance Can Help Ensure Longer Service Life. However, using an epoxy-based resin will ensure that the product cures hard and bonds securely to the surface. Polyurethane: Expensive But Durable Finishing Products (300) Polyurethane delivers a tough and flexible coating to wood. This creates a well-adhered system base that will allow subsequent build and topcoats. In the industrial floor coating world, while epoxies and polyurethanes are both thermosetting polymers, their differences in function and performance are vast. Epoxy. Lazonby, John. Some other names for these co-reactants are hardeners or curatives. However, epoxy resins will begin to gel in as quick as 20 minutes, whereas casting resins may take upwards of 18 hours to gel. • Epoxy is preferred in most industries as it sets much faster than resin. A polymer is a macromolecule that contains a large number of small repeating units (monomers). It's said that one pouring of epoxy resin is "equal to 60 coats of polyurethane" in thickness, but it isn't necessary to use a resin just to get a high gloss effect. If we increase the amount of bisphenol A (compared to epichlorohydrin), it provides high molecular weight polymer material. Epoxy vs Resin • Epoxy is the name of an ingredient as well as the end product of epoxy resin manufacturing. Polyurethane really needs to go on in individual coats to build up to a finish, which means you shouldn’t spray it on to the wood. What is Epoxy? • Epoxy is resistant to water, heat, and chemicals whereas resins are not. Novolac epoxy resins for high temperatures. This polymer material is linear and is semi-solid crystalline materials. Often, I receive a call from a facility manager who has been tasked with coating his or her production floor. As described above, epoxy is lighter, stronger, and more environmentally friendly. The conversation usually starts off something like this: “I need you to take a look at my concrete floor,” the facility manager says. The downsides of choosing polyurethane are: You need to brush big jobs. Epoxy creates a hard protective coating that bonds to concrete or steel. Epoxy Technology. In summary – Epoxy vs Polyurethane. Epoxy vs Resin. 4. 1. Compare the Difference Between Similar Terms. While curing epoxy creates a strong bond with the concrete substrate and ultimately provides a repair of high compressive and tensile strength properties. The epoxy/cloth laminate is comparable to using polyester resin with 3/4 oz. Epoxy resin dries, or cures, to a very hard, unexpansive surface and is only suitable for indoor use. Overview and Key Difference What is Polyurethane Quick comparison between Epoxy Resins and Polyurethane Resins formulated for Concrete Crack Injection ... Epoxy resin needs to be contained in a crack until cured sufficiently to achieve full strength. The blending of the 2 components for each resin type creates a material with the requisite properties for professional crack injection repairs. 3. This thickness allows the coating to chemically bond to the epoxy primer, and is thick enough to self-level and fill minor concrete blemishes and hairline cracks. This makes polyurethane coatings more resistant to scratches and similar damage and is why you’ll often find urethane resin floors in heavy traffic areas – such as multi-storey car parks. Epoxy resins may be reacted (cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols. 3. It resembles plastic with more durability. PU casting resins can, just like epoxy resin and polyester resin, be combined with various additives as well as filling materials or colorants. “It’s bare concrete and we need it to be durable, bright, safe and easy to clean. De manière générale, ce genre de revêtement de sol est utilisé dans le but de couvrir un entrepôt, ou de grands espaces. Unfortunately, I’m not familiar with wood fillers. In this guide, we’ll compare epoxy resin and polyurethane resin: keep reading to learn more. Epoxy is more plastic in texture and forms a hard bond once cured. With a limited pot life and risk of humidity issues, your staff needs to work quick and smart for good results. Though they exhibit much thinner cured-film thickness, polyurethanes offer a number of unique advantages over epoxies. Isocyanates and polyols undergo polymerization to form a polyurethane. As a varnish style coating. It all depends on what your project is as to whether you would choose epoxy resin or polyester resin. Flexible and elastic properties go to both of these options and each substance is used in the automotive industry, in the manufacture of certain parts. The epoxy resin is less toxic to the board builder and the environment. Difference Between Copolymer and Homopolymer, Difference Between Polystyrene and Polypropylene, Side by Side Comparison – Epoxy vs Polyurethane in Tabular Form, Difference Between Coronavirus and Cold Symptoms, Difference Between Coronavirus and Influenza, Difference Between Coronavirus and Covid 19, Difference Between Oleic Acid and Elaidic Acid, Difference Between Apple A7 and A8 Processors, Difference Between Microarray and RNA Sequencing, Difference Between Filgrastim and Lenograstim, Difference Between Parallel and Antiparallel Beta Pleated Sheets, Difference Between Sodium Citrate and Citric Acid, Difference Between Hypersil and Inertsil Column, Difference Between Trypanosoma Cruzi and Trypanosoma Rangeli. Polyurethanes provide the enhanced performance characteristics that protect the entire system. We will take a look at some of the differentiating factors between the two so you can decide what product suits your floor best. In this guide, we’ll compare epoxy resin and polyurethane resin: keep reading to learn more. The key difference between epoxy and polyurethane is that the epoxy contains epoxide groups whereas polyurethanes contain urethane linkages. Johnson, Todd. But which material should you choose for your floors? Resin coatings, such as epoxy or polyurethane, help make flooring materials meet the needs of various industries. As a result, this can be made very variable to suit any application. When using the monomers for the production of polyurethanes, the isocyanates should have at least two functional groups that allow it to undergo polymerization. Although the name polyurethane gives an idea that the polymer consists of urethane monomers, it in fact, consists of urethane linkages, not monomers. Bonding to Concrete: Provided the concrete substrate is properly prepared to receive a coating, epoxies are excellent for mechanically bonding to concrete. These polymers get their name according to the repeating linkages present in the polymer material instead of the monomers used for the production. As far the features and benefits, it is a durable choice for many kinds of labs. Polyurethane Resin vs Polyesther Resin. Figure 02: A Chair made from Polyurethane. These polymers form via glycosylation of aliphatic alcohols or polyols. This resin has many different uses, besides just as a floor coating. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } “I thought all floor coatings were ‘epoxy’,” the facility manager quips. Prior to that, Sean worked in the construction industry, specializing in contract and project management for commercial and industrial floor and roof projects. PU/PE are built using a polyurethane foam blank and then glassing it with a polyester resin. Protective Industrial Polymers is a unique company devoted to providing turn-key flooring solutions for today's industrial marketplace. Overall, epoxies are the preferred materials for priming properly prepared concrete substrates, and providing ‘build’ or film thickness that can hide small blemishes or hairline cracks on the concrete surface. Not sure what type of polymer floor coating system your facility requires? Epoxy resins can resist moderate temperatures. • Resins are used more in construction where there is no hurry for the final product. Like epoxy, polyurethane also comes in different formulations. Available here  A particular draw of using PU foam is that it is closed cell—meaning it won’t easily soak up resin or water (should you ding your board), which helps keep the board light. Depending on the desired performance requirements and condition of the concrete, more build coat applications may be desired. Sean enjoys working closely with PIP’s sales and management group to develop and market new flooring products and systems to address end-user’s unique requirements. It all depends on what your project is as to whether you would choose epoxy resin or polyester resin. We can leave those intracacies for another blog article. In fact, in many cases, if the epoxy primer and build coats are well-bonded, a simple re-coat of the polyurethane topcoat may be all that is required every few years, depending upon use. In the application point of view, the main difference between epoxy and polyurethane is that the epoxy resins can resist moderate temperatures while the polyurethanes can withstand high temperatures. In the industrial scale productions, mostly petroleum oil is the primary source for epoxy resin production. Available here 1. This chemical protects against damage, UV rays, and water. Of course, concrete preparation is a crucial part of establishing a proper bond. We also have crack and spall epoxy-based products that are USDA approved for meat and poultry plant-based applications. • Epoxy is stronger than resin. Of these, aliphatic polyurethane is the preferred option when it comes to garage floor coating applications. Epoxy adheres to wood much better than polyester does. Epoxy resin dries, or cures, to a very hard, unexpansive surface and is only suitable for indoor use. “What’s the difference with epoxy vs polyurethane coatings?” In the industrial floor coating world, while epoxies and polyurethanes are both thermosetting polymers, their differences in function and performance are vast. Can I use any kind of paint on the cast piece? Here we use bisphenol F in the place of bisphenol A, but the way of formation of the polymer is same as the bisphenol A epoxy resin (as discussed above). From an applicators point of view polyurethane floor resins are extremely sensitive to the presence of humidity. Additionally, the offer excellent resistance to staining from hot or cold tires. Resin vs Epoxy: below is a list of these main resin categories: Polyester Resin: This is not an actual epoxy but is rather an unsaturated synthetic resin; Epoxy Resin: This type is supplied in 1 or 2 component forms; Polyurethane Resin: This is also not an actual epoxy but is rather a synthetic resin or plastic If you are repairing an epoxy product, then epoxy should be used for the repair (polyester will perform poorly in this case). With the number of advantages polyurethanes have over epoxies, why would one choose one coating technology over the other? Epoxy is a strong adhesive or glue that does essentially not expand. Terms of Use and Privacy Policy: Legal. Like epoxy, the 2 components are mixed before they are injected into a foundation crack. The key difference between epoxy and polyurethane is that the epoxy contains epoxide groups whereas polyurethanes contain urethane linkages. “Epoxy.” Wikipedia, Wikimedia Foundation, 19 Apr. They are also called plastic adhesives, and they are also used to bond together plastics, glass, and metals. Epoxy resins are also sensitive to moisture, but the damage done by humidity will be far more limited. Epoxy resins less flexible and less abrasion resistant. The upsides of using polyurethane are: Superb look. Generally, a polyurethane floor coating is highly flexible and elastic, while epoxy flooring is harder and more brittle. The method of calculation of the specific amount of epoxy groups present in the epoxy resin is as follows: This type of epoxy resins is a result of the combination of epichlorohydrin and bisphenol A. this combination gives bisphenol A diglycidyl ethers. When looking for flooring for your business, there are many options out there. 5 days for base and 8-12 hours for overcoats undercuts epoxy cure times but disrupts the use of your space significantly. Upon curing, the epoxy build coat(s) provide a hard, durable surface. These range from flexible epoxies, to chemical-resistant epoxies, to fast-setting epoxies, etc. • Resins are used more in construction where there is no hurry for the final product. 5. Polyurethanes "dry" in a fairly short time, but resins "cure" instead of drying and that takes at least 24 hrs. Moreover, polyol also should have at least two hydroxyl groups per molecule. These two components are thoroughly mixed together, applied to the concrete floor, and allowed to cure. A: Acrylic resin (but not acrylic emulsion, which is the basis of acrylic paint) is a thermoplastic, which means it is one of a group of plastics which can be heated and manipulated repeatedly, whereas polyester resin and epoxy are thermosetting plastics, which use heat or a catalyst to solidify into a solid mass that won’t melt down. Polyurethane coatings perform very similar to Polyaspartics but they take longer time to cure (at least 24 hours) and need to be applied very thin (4 to 6 mils per coat) Polyurethane coatings are used mostly top coats over Epoxy coatings. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. Polyurethane is generally more resistant to scratching, chemicals, UV rays, and general wear and tear than epoxy. In very simple terms, a typical two-part epoxy coating contains a resin side and a hardener side. With 98% solids, polyurea is 4x stronger and yet 98% more flexible than epoxy. Polyurea is a subgroup of polyurethane. cloth however the epoxy laminate requires much less labor to fair. 5. However, epoxy and polyurethane can be used together to create a very strong flooring system. The monomers for polyurethane are polyols and isocyanates. From a form and function standpoint, epoxies are very good at three things: On the other side of the coin, epoxies are sensitive to UV light so they will amber or yellow over time when exposed to sunlight. Polyurethane resin, on the other hand, is up to 50 times more expansive than epoxy resin, making it far more resistant to cracking and therefore suitable for indoor or outdoor use. Odor. Resin and epoxy are both adhesives commonly employed in the construction industry. Aside from the elastic durability factor which makes polyurethane the number one choice by default, the resin is also more scratch-resistant, crack-resistant, temperature resistant and chemical resistant than epoxy.
