ADCOTETM 64-120/CR 857

Laminating Adhesive 

Description and Features

Adcote 64-120 adhesive is the polyester component of a two component laminating adhesive which requires 

the use of an isocyanate coreactant. This polyester in conjunction with various isocyanate terminated 

coreactants functions as an adhesive for a variety of industrial laminations.

Adcote 64-120/CR 857 adhesive adheres to a wide variety of substrates including cellophane, treated 

polyolefins, polyester, polyamide, aluminum foil, metallized and PVDC coated materials, PVF, and the 

treated heat-sealable layers of coextrusions.

Adcote 64-120/CR 857 adhesive provides whiteness, good hiding, high bond strength, and a high level of 

heat and chemical resistance.

This adhesive has shown good heat and humidity resistance in back sheet structures for photovoltaic 

modules with damp heat resistance (85C, 85%RH) >2000 hours* and non-yellowing characteristics.*
