ADCOTE™ 545E

Adcote™ 545E is an ethyl acetate solvent analog of Adcote™ 545. Adcote™ 545E 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™ 545E 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 coextrusions.

Features & Benefits

Adcote™ 545 adhesive provides optical clarity, high bond strength, and a high level of heat and chemical resistance.
