ADCOTE™ 503A

Adcote™ 503A is the polyester component of a solvent-based two-component laminating adhesive. An isocyanate-terminated co-reactant such as Coreactant F is required. The conjunction of Adcote™ 503A and co-reactant functions as an adhesive for flexible packaging and industrial lamination applications.

The adhesive formed with Adcote™ 503A adheres to a wide variety of substrates including cellophane, treated polyolefins, polyester, polyamide, aluminum foil, metallized and PVDC-coated materials and treated heat-sealable layers of coextrusions.

Features & Benefits

Adcote™ 503A provides great optical clarity, high-bond strength, as well as superb heat and chemical resistance.
