ADCOTE™ 545-80

Adcote™ 545-80 is a solvent-based, two-component polyurethane adhesive with high solid characteristics, and excellent heat and chemical resistance. This polyester adhesive is used in conjunction with various isocyanate terminated coreactants and functions as a laminating adhesive for flexible packaging and industrial applications. Adcote™ 545-80 adheres to a wide variety of substrates including cellophane, treated polyolefins, polyester, polyamide, aluminum foil, paper, metalized and PVDC coated materials, and the treated side of heat-sealable coextruded films. Typical uses of Adcote™ 545-80 with Coreactant F include lamination of transparent and aluminum-containing structures with and without sandwich printing. These laminates are flexible materials used for food pouches, vacuum or gas flushed luncheon meats and cheese, coffee pouches, condiment packaging, cable wrap laminations, liquid packaging, hygroscopic powders, chemicals, and cosmetics.
