Isocyanate Hardener
FEICURE GB805A-100
Alternative to Desmodur E15
FEICURE GB805A-100 is a solvent-free isocyanate curing agent with active NCO groups. It is designed for high-solids, low-viscosity and environmentally friendly coating systems, especially when used with polyaspartic resins, providing excellent elongation, tensile strength, water resistance and low-temperature resistance.
