Polyurethane adhesive industry applications

　　Polyurethane adhesive (PolyurethaneAdhesive) means a carbamate group (-NHCOO-) in the molecular chain or an isocyanate group (-NCO) adhesive.

　　Polyurethane adhesive with excellent performance, and should be widely fields. It is divided into polyisocyanate and polyurethane two categories. Because it contains very polar, high chemical inertness of the isocyanate group (-NCO) and urethane group (-NHCOO-), it active hydrogen-containing materials, such as foam, wood, leather, fabric, paper, ceramics and porous materials such as metal, glass, rubber, plastics and other smooth surface materials with excellent chemical adhesion. The hydrogen bond is created between the polyurethane and polymer adhesive material effect will increase cohesion. So that the bonding stronger. In addition, polyurethane adhesive toughness also has an adjustable, simple bonding process, a very good low temperature performance and excellent stability characteristics, in recent years, at home and abroad has become the fastest growing adhesive.

　　Technological developments of polyurethane adhesive: two-component polyurethane adhesive. This polyurethane adhesive is the most important class, versatile, large amount. Shanghai haksong polyurethane adhesive for production of environmentally friendly two-component adhesive rubber powder, solid content, high initial adhesive strength after drying has excellent adhesive strength, scratch resistance, excellent water resistance, widely used for bonding rubber and organic materials.
