LAMAL™ HSA
LAMAL™ HSA is a polyether urethane that is used in a two component laminating adhesive system for the manufacture of flexible packaging.
LAMAL™ HSA is a solution based polyurethane in ethanol. It is used in combination with an isocyanate coreactant like LAMAL™ C as a two component urethane adhesive. LAMAL™ HSA is ideally suited for laminating films commonly used in flexible packaging. It provides good adhesion to and bonding of many common packaging materials including polyethylene, polypropylene, PET, paper, cellophane, and PVC. LAMAL™ HSA exhibits good humidity resistance for a polyurethane adhesive and is used in laminations for flexible packaging that are subjected to heat and moisture.
