PUR hot-melt adhesive -PUR1005
Product introduction
PUR (PolyurethaneReactive), is moisture curing reactive polyurethane hot melt adhesive. The main component is isocyanate polyurethane prepolymer.After heating at high
temperature, PUR adhesive molecules reacts with water or active hydrogen reactive substances in the air or on the sticky part of the formation of cross-linked structure,
the adhesive strength, resistance to chemicals, heat, hydrolysis and other excellent performance general hot melt adhesives.Adhesion and toughness (elasticity) can be adjusted
with a cold-performance thermoplastic hot melt adhesive ordinary,easy to operation, receiving wide range and big adjustability performance.
Product advantages for PUR hot melt adhesive
1.Does not contain any organic solvents, solid content 100%, green;
2.Moisture curing, no drying process, quick energy;
3.Excellent initial strength, but also has the function of crosslinking, the higher the final bond strength;
4.Excellent heat resistance, water resistance, chemical resistance, durability and etc;
5.One-component type, easy to industrial automation, mechanization operation, high production efficiency.
