ADCOTE™ 532A

Adcote™ 532A is the isocyanate-terminated polyester urethane component of a two-component, high application solids adhesive system which requires the use of coreactant Adcote™ 532B to achieve full properties. The adhesive combination adheres to a variety of substrates with excellent heat and chemical resistance.

Adcote™ 532A/532B is designed for laminating aluminum foil and a variety of polyester, nylon, EVOH, polyolefin and co-extruded films typically used in food, medical and industrial packaging applications.

Features & Benefits

Adcote™ 532A/532B was specifically designed for optimum performance where slip modified films are used and applications requiring excellent heat and chemical resistance. It can be used where a low nip temperature is required when producing temperature sensitive constructions.
