Activators and Catalysts are a mixture of polyisocyanates, solvents and additives. Catalysts differ in the type of isocyanate used, the percent solids of isocyanates, and the solvent blends. The type of and amount of isocyanate will control the rate of cure, durability, gloss level, UV resistance, hardness, chemical resistance, etc. The solvent blend will determine the flow out and dry times.
