Product Overview
MOR-FREE™ 421 is used in combination with coreactant C-145, C-132, or C-411 as a 100% solids laminating adhesive system. It provides outstanding adhesion to high slip films and can be used to laminate polyolefin films to nylon, aluminum, polyester, and other polyolefin films. MOR-FREE™ 421 has a very fast bond development and laminates made with it can usually be processed within 4-8 hours post lamination. This allows for faster run speed and increased efficiency. MOR-FREE™ 421 is 21 CFR175.105 compliant and is commonly used in snack food packaging, frozen food packaging, and confectionery packaging applications.
