Isocyanate Hardener
FEICURE GB963B-100
Alternative to Desmodur E30700 (E2863XP)
FEICURE GB963B-100 is a solvent-free aliphatic polyurethane prepolymer curing agent. With very low viscosity, high elasticity and excellent weather resistance, it is suitable for high-solids weather-resistant topcoats, offering good flexibility, tensile strength, scratch resistance, long-term UV resistance, and excellent resistance to acid, alkali and salt spray.
