MOR-FREE™ 403A is a solventless, two component polyurethane adhesive that is used as a laminating adhesive for flexible packaging.
MOR-FREE™ 403A is a 100% solid, 2 part laminating adhesive that provides outstanding adhesion to metal and high slip films. It should be used with Coreactant C-411, C-117, or C-132-2. MOR-FREE™ 403A is typically used in flexible packaging applications that require good heat and chemical resistance like stand up pouches, condiment packaging, and confectionery packaging.
