FEISPARTIC F520
Shenzhen Feiyang Protech Corp., Ltd · FEISPARTIC
FEISPARTIC F520 is a solvent-free polyaspartic resin developed as an aminofunctional co-reactant for polyisocyanates in high-performance coating systems. It combines high solids content with low viscosity and extended pot life, enabling the formulation of durable, high-build or solvent-free coatings. The resin delivers excellent film properties including high gloss, smooth leveling, and strong adhesion to plastics and metals. It exhibits outstanding resistance to weathering, water, chemicals, and abrasion, along with high hardness up to 2H. Its broad compatibility and good wettability make it particularly suitable for automotive coatings, industrial finishes, anti-corrosion systems, and high-performance color pastes used in demanding environments.
