Polyaspartic Resin
Feispartic F424
FEISPARTIC F424 is a low-viscosity, fast-drying bifunctional cyclic polyaspartic resin designed for solvent-free polyaspartic polyurea coatings, adhesives and other high-performance systems. Used with isocyanate hardeners, it provides a longer pot life than FEISPARTIC F420 while delivering good hardness, flexibility, weather resistance and mechanical strength.
