However, polyaspartic aliphatic polyurethane is different. Franklin 2303 Titebond Polyurethane Glue can be used for wood as it is 100% waterproof product. The monomers for epoxy resins are phenols and epichlorohydrin, but the monomers may vary depending on the type of epoxy resin. It is recommended that materials be clamped during curing which occurs in approximately four hours (Note: Check the manufacturers cure time on the packaging as some polyurethane glues have cure times as long as 24 hours). The most common mixing ratios of adhesive to hardener are either 100:15 or 100:30. Chemical-Resistance: Polyurethanes are resistant to a broader range and concentrations of chemicals. Polyurea and Polyaspartic Concrete Coatings vs. Epoxy. These polymers get their name according to the repeating linkages present in the polymer material instead of the monomers used for the production. It’s not a stronger joint.” Other glue manufacturers disagree. Selon le support à coller, les colles sont dites époxy, néoprène, cyanocarylate, polyuréthane ou encore polymère. Epoxy vs Polyurethane. Polyurea VS Epoxy. They offer chemical resistance and waterproofing. Both epoxy and polyurethane are polymer materials. “Epoxy.” Wikipedia, Wikimedia Foundation, 19 Apr. Epoxy and polyurethane are booth chemical resins with different reaction profiles and physical properties. It fails to bond as strongly as epoxy does to cement. These polymers form via glycosylation of aliphatic alcohols or polyols. Its setting time is 1-4 hours. Most polyurethanes also have high VOC level and will have quite an odor when applied. While all of our epoxy and polyurethane flooring products are suitable for DIY installation, the high sensitivity to moisture and the fast cure time of PU systems make the installation process far harder than that of hardier epoxy resin options. Polyurethane is also a polymer material that contains urethane linkages. Epoxy is an excellent adhesive to use for concrete surfaces. Which coating would you recommend?”. The monomers for polyurethane are polyols and isocyanates. 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). Epoxies and polyurethanes behave differently when exposed to certain chemicals. Epoxy and polyurethane are great for protecting your floor against stains, damage, chemicals, oils, and wear. 2. The bottom line, experts say, is that polyurethane glue is much more stainable than yellow glue because it sits on top of the wood and doesn’t seal the pores of the wood the same way that yellow glue does. In fact, the lifespan of the PU system is roughly double that of the epoxy, clocking an impressive ten-year’s compared to the epoxy’s five. This polymer material is linear and is semi-solid crystalline materials. There’re 3 kinds glues, they are epoxy resin glue, PU (polyurethane) glue and silicone glue. Its setting time is 1-4 hours. However, there are some plant-derived sources as well. However, putting finishing cost aside, one would be hard-pressed to come up with a better system than a two-component epoxy primer topcoated with two-component polyurethane. We have meticulously assembled complete systems that will cover what we state and beyond.

To be crystal clear, you will be pleased with any of these products if you take the time to do it properly. Cependant, sa résistance chimique et son adhésion sont plus faibles par rapport à celles d’une résine époxy. Some resins require thin pours while others require long cure times. Show comparatively low resistance towards organic acids, Shows high resistance towards corrosion, inorganic acids, alkali solvents, organic alkalis and many other solvents. 2, The PU (polyurethane) glue is better than epoxy resin glue because of its good yellow degeneration resistance, good Low temperature resistance, but not resistant to high temperature. A good alternative is epoxy resin glue. All rights reserved. These finish systems are used in extreme outdoor exposure conditions. It is said that epoxy offers higher strength than urethane. Re: Polyurethane glue or epoxy? The keys to understanding whether to use e… When I've checked, polyurethane has always been more expensive than the epoxies most boatbuilders use. Polyurethane two-component adhesives are divided into different degrees of hardness. PU also resists damage from many different threats well, including solvents, alkalis, and sources of corrosion. Pour coller de la faïence, de la porcelaine, du plastique, du métal ou même du bois, les colles sont devenues indispensables. Even though epoxy is harder, the flexibility afforded by PU is valuable in many industries. The crack was larger, thereby reducing the structural integrityof the foundation. Polyurethane glue has a lot of the same qualities as epoxy without the disadvantage of requiring the mixing of a resin and hardener. On nous demande souvent quelles sont les différences entre l’époxy et le polyuréa. Side by Side Comparison – Epoxy vs Polyurethane in Tabular Form Polyurethane glue has a lot of the same qualities as epoxy without the disadvantage of requiring the mixing of a resin and hardener. Of course, concrete preparation is a crucial part of establishing a proper bond. 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. And when should we pick one over the other? Once the plastic foam has cured, it becomes hard, durable and waterproof. This practice over time made things worse. 2. Epoxy and Polyurethane coatings exemplify superior long term qualities such as chemical and acid resistance, ease of maintenance, and aesthetic appeal.

It is formed when isocyanates react with water or polyetheramines to create a urea linkage. Epoxy Adhesives. These two components are thoroughly mixed together, applied to the concrete floor, and allowed to cure. Increased Impact and Abrasion Resistance: Polyurethanes exhibit excellent impact and abrasion resistance, providing up to four times longer life than uncoated epoxy floors. Madhu is a graduate in Biological Sciences with BSc (Honours) Degree and currently persuing a Masters Degree in Industrial and Environmental Chemistry. This the reason why many food processing companies that … Polyurethane also has a short shelf life while unmixed epoxy lasts a looong time. Polyurethanes do not bond well to concrete and do not exemplify the self leveling properties that epoxies do when applied to on these surfaces. As it is durable, non-porous, and reasonably economical, epoxy resin is the most common choice for many kinds of labs. Like epoxy, polyurethane is a thermosetting polymer as well and is considered a high performance coating. Epoxy vs. Urethane: Sealing Cracks in Poured Concrete Foundation. There are a number of different epoxy floor coatings on the market today, with costs that are all over the map. when it comes to hardness epoxies are much stronger but polyurethane are more scratch resistance. Un polyuréthane ou polyuréthanne est un polymère d'uréthane, une molécule organique. It passes ANSI type 1 and 2. Polyurethanes provide the enhanced performance characteristics that protect the entire system. Whilst a polyurethane system will initially cost more compared to an epoxy, it is far more cost effective in the long term. Is Floor Cleaning and Maintenance Part of Your Safety Program? Polyurethane glue's foaming characteristic gives it superior gap-filling properties, as it expands to fill any available space. Epoxy is not resistant to ultraviolet light so, while it will not change color immediately, the epoxy will begin to yellow after several months or years. 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. Epoxy and polyurethane (PU for short) floors are the two most commonly used types of resinous industrial floors. Epoxy and urethane are important components in the adhesive and foam industries.
