Differences Between Epoxy vs.Polyurethane Thin Film Topcoats By Sophia Daukus on October 17th, 2016 in Commercial & Retail , Installation Epoxy and polyurethane thin film topcoats are two types of high performance floor coatings that can be used to strengthen, protect, and improve the aesthetics of an industrial flooring system. Whilst a polyurethane system will initially cost more compared to an epoxy, it is far more cost effective in the long term. Owners at Industrial Facilities often come to us wondering what type of coating system (epoxy vs polyurethante) is needed to protect their assets. Polyurethane’s surface may not be as hard or thick as epoxy. One concern with polyurethanes is their sensitivity to humidity and moisture. Epoxy is an excellent adhesive to use for concrete surfaces.

What are the Best Industrial Coatings for Structural Steel? You see examples of powder coating on a vast range of everyday appliances and household fixtures, such as stoves, refrigerators, laundry machines, tables and lamp vases. Epoxy and Polyurethane coatings exemplify superior long term qualities such as chemical and acid resistance, ease of maintenance, and aesthetic appeal. 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. 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. (MCU-100, MCU-101, MCU-104), – Acrylic Polyurethanes: Acrylic Polyurethanes are known for their excellent gloss and color retention, UV resistance, and provides a tough and durable finish. Most H.S.

Applying one or two coats of polyurethane over paint would be a great move more than that would be futile. There is some downside to 100% Solids Epoxies. (PC-240), – Phenalkamines: Phenalkamine cured epoxies are excellent for low temperature / cold weather applications. Acrylic Polyurethanes are usually made with an aliphatic compound which provides the long term stability needed in an Acrylic Polyurethane. 2 Comments. Polyurethane also has a clear advantage over epoxy when it comes to UV stability. Powder coating achieves a thicker and more consistent finish than you usually get with spray paint. Usually these epoxies are economical and are used a primer and finish coat. This means there little to no VOCs in the epoxy as this will give you the strongest coating when applied. Once dry its completely waterproof and will not leave marks on furniture from a glass. or 251-964-7911 for assistance on your upcoming coating project.
