ADCOTE™ 50C12 is a water based acrylic dispersion that is used as a heat seal coating and primer for extrusion coating aluminum foil with polyethylene.
ADCOTE™ 50C12 is a water-based dispersion of ethylene acrylic acid that exhibits outstanding adhesion to metal foils and paper. It provides good resistance to oil, grease and moisture. ADCOTE™ 50C12 is often used as a primer for extrusion coating aluminum foil with polyethylene, EVA, and acrylics. ADCOTE™ 50C12 is thermoplastic and can be used as a heat seal coating. When applied to foil, paper, or polyethylene it forms a grease resistant coating that can be subsequently heat sealed to films common in the flexible packaging industry including polyethylene, foil, and paper. Seals formed with ADCOTE™ 50C12 are resistant to moisture as well as oils and grease. This makes it ideally suited for heat sealing and lidding of packaging for difficult products like agricultural chemicals and condiments.
