ADCOTE 503E

Adcote™ 503E 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 flexible packaging and industrial laminations. Adcote 503E adhesive adheres to a wide variety of substrates including cellophane, treated polyolefins, polyester, polyamide, aluminum foil, metallized and PVDC coated materials, and the treated heat sealable layers of co-extrusions.

Features & Benefits

Adcote™ 503E adhesive provides optical clarity, high bond strength, and a high level of heat and chemical resistance.
