The following list of epoxy information points will get you up to speed fast. There are always exceptions to everything and no doubt someone could debate nearly every point made below. However, in general, and to the best of my knowledge, the information below holds true and will make you immediately knowledgeable about epoxies. Epoxy coatings are used because of their outstanding chemical resistance, durability, low porosity and strong bond strength.
Epoxies consist of a base' and a curing' agent.
The two components are mixed in a certain ratio. The yellowing can be a real problem. Even clear epoxies will yellow and cloud up. Often epoxies are topcoated with latex or urethanes that will retain their color and attractive gloss. This is particularly true if color coding or matching company colors is important.
