TOCPOLY NH-252 Polyaspartic Polyurea Resin

This amine-functional resin can react with polyisocyanates, designed for formulating high-solids two-component polyurethane topcoats and solvent-free coatings, and delivers excellent anti-corrosion and waterproof performance.

Product Characteristics

This amine-functional resin can react with polyisocyanates, designed for formulating high-solids two-component polyurethane topcoats and solvent-free coatings, and delivers excellent anti-corrosion and waterproof performance.

Supply Form

Solvent-free low-viscosity liquid

Product Advantages

High solids and low viscosity, suitable for manufacturing low-viscosity solvent-free eco-friendly coatings

The cured film features outstanding fullness, leveling property and gloss

Exceptional resistance to weathering, water, solvents, acids, alkalis and salt spray

Hard coatings formulated with this resin show superior abrasion resistance: abrasion loss ≤0.02 g (500 revolutions / 750 g load)

Excellent adhesion to plastics (ABS, PC, PVC) and metals including galvanized steel, stainless steel, aluminum sheets, aluminum foil and copper foil when matched with TOCPOLY dedicated curing agents

Excellent compatibility with most hydroxy acrylic resins, CAB and other resins
