Introduction of Polyurethane Adhesive

- Aug 15, 2019-

Polyurethane adhesives are adhesives containing carbamate group (-NHCOO-) or isocyanate group (-NCO) in the molecular chain. Polyurethane adhesives are divided into polyisocyanate and polyurethane. Polyisocyanate molecular chain contains isocyano (-NCO) and carbamate (-NH-COO-), so polyurethane adhesives show high activity and polarity. 

It has excellent chemical adhesion with materials such as foam, plastics, wood, leather, fabrics, paper, ceramics, and porous materials such as metal, glass, rubber and plastics.
