Polyurethane Composite Adhesive
Polyurethane adhesive refers to the adhesive containing carbamate group (-NHCOO-) or isocyanate group (-NCO) in the molecular chain. Polyurethane adhesives are divided into two categories: polyisocyanate and polyurethane.Polyisocyanate molecular chains contain isocyano groups (-NCO) and carbamate groups (-NH-COO-), so polyurethane adhesives exhibit high activity and polarity. It has excellent chemical adhesion to substrates containing active hydrogen, such as porous materials such as foam, plastic, wood, leather, fabric, paper, ceramics, and materials with smooth surfaces such as metal, glass, rubber, and plastic.
Application:
Polyurethane Composite Adhesive can be used for laminating polyester film,polyimide film and non-woven fabric.

Substrate characteristics
The conditions of film additive, corona treatment, coating, equipment tension and temperature control system are critical importance and will directly or indirectly affect the end use performance for composite products. In mass production, before the actual compound test and proper inspection of the composites were necessary. Due to the actual use conditions of the product are beyond the control of the company. Therefore, the company cannot guarantee the end use.
