Alka 204 is a two component, clear, solvent-based polyaspartic topcoat designed for use over concrete floor coatings. Alka 204 is very high gloss, low viscosity topcoat. In comparison to the conventional solvent-based polyurethane coatings, polyaspartic coatings show a much higher abrasion resistance and flexibility. In fact, aliphatic polyurea or polyaspartic family of resins are the next generation of polyurethanes.
