MICA water-based primers are an integral part of high quality, multiple layer flexible laminates produced by extrusion coating and lamination. In addition to polyolefin extrudates, MICA primers enhance the bonding of inks, PVdC, SiOx, and other coatings to paper, film, and aluminum foil substrates. All MICA primers are environmentally responsible, safe and easy to use, provide high bond strength for durability and have a long storage and pot life.
WATERBORNE EXTRUSION PRIMER
MICA G-782 is a multipurpose water-based primer designed to promote the adhesion of extruded polyethylene to various supporting films and papers. SiOx coated films are among the substrates to which MICA G- 782 provides superior adhesion. This primer contributes excellent moisture resistance to the subsequent SiOx/PE laminate. MICA G-782 also bonds strongly to AlOx surfaces.
