Overview
PACACEL™ L75-191 is designed to be used with a polyol coreactant, such as coreactant 88-141, to create a 100% solids polyurethane solventless adhesive system. This two-component adhesive system offers incredibly fast run speeds and cure time to allow converters to capture and fulfill more just-in-time business orders. Laminates made with the PACACEL™ L75-191 system are ready for slitting in four hours, pouching in 24 hours, and food contact in two days. This adhesive system has broad FDA compliance and can be used in food and pharmaceutical packaging applications. PACACEL™ L75-191 offers excellent adhesion to combinations of PE, PET, OPP, cellophane, CPP, nylon, metallized films, and foil.
