Disadvantages: Urethane coating require an epoxy primer coat as they do not bond as well as epoxies. Epoxies mechanically bond to surfaces and urethane chemically bonds to the epoxies. They are more expensive than epoxies and acrylics. They are two component products that requires fairly exacting mixing proportions and procedures.

 

Usage: Concrete floors and walls, top coat for steel; structures, tanks, "computer clean" rooms, medical sterile rooms, food and biological applications. Used in warehouses, machine shops, automobile service departments, bridges, and for anti-graffiti applications.
