This amine-functional resin can react with polyisocyanates and is formulated for high-solids two-component polyurethane topcoats and solvent-free coatings, delivering outstanding anti-corrosion and waterproof performance. It is equivalent to NH-1420 with lower viscosity and higher reactivity.
Supply Form
Solvent-free low-viscosity liquid
Product Advantages
· High solids and low viscosity, enabling production of low-viscosity solvent-free eco-friendly coatings
· Cured film boasts excellent fullness, leveling property and gloss
· Superior weather resistance, water resistance, solvent resistance, acid & alkali resistance and salt spray resistance
· Fast curing speed when matched with standard HDI trimer: tack-free in 18 minutes, suitable for quick-dry applications
· Excellent adhesion to plastics including ABS, PC, PVC, as well as metals such as galvanized steel, stainless steel, aluminum sheet, aluminum foil and copper foil when combined with TOCPOLY matched curing agents
· When reacted with TOCPOLY elastic curing agents to produce elastic coatings or adhesives: elongation up to 400%, tensile strength of 25 MPa. Coatings made with TOCPOLY rigid curing agents reach 2H film hardness with extraordinary abrasion resistance; abrasion loss ≤0.02 g (500 revolutions / 750 g load)
· Outstanding compatibility with most hydroxy acrylic resins, CAB and other resins
· Used as main resin and chain extender for Component R of SPUA (Sprayed Polyurea Elastomer)
