Product Overview
MOR-FREE™ L 75-164 is designed to be used in combination with a polyol coreactant like MOR-FREE™ C-411 to make a 100% solids polyurethane laminating adhesive. This adhesive system offers incredibly fast bond development and full cure strength within 3 days at room temperature. Laminates made with this adhesive can be further processed in as little as 4 hours post lamination. MOR-FREE™ L 75-164 has excellent moisture, heat, and chemical resistance and can be used in laminations for boil in bag, hot fill, and microwave packaging applications. In addition, offers excellent adhesion to high slip films and foils including LDPE, OPP, and aluminum.
