Overview
Coreactant CR 3A is the curing agent of a two-part acrylic waterborne laminating adhesive system using ROBOND™ L-2152. The adhesive system comprising ROBOND™ L-2152 and Coreactant CR 3A provides excellent adhesion to metallized and PVDC-coated materials, coextruded heat-sealable layers, paper, cellophane, treated polyolefins, polyester, vinyl, aluminum foil, and more. This low-VOC system provides high bond strength, excellent optical clarity, and strong heat and chemical resistance in flexible packaging and industrial film–film and film–foil laminates.
