Covinax 169-04 is a polyvinyl alcohol stabilized vinyl acrylic copolymer emulsion developed for a variety of permanent pressure sensitive applications requiring very aggressive wet and dry tack. It exhibits outstanding adhesion to most synthetic films, including treated and untreated polyethylene and polypropylene, Tyvek® and Cryovac®. It performs well in low temperatures and is widely used in packaging. Covinax 169-04 is formulated to be a wash-away adhesive. The polyvinyl alcohol colloid allows easy cleanup and imparts excellent machining. It can be applied with a knife, rod, roll coater or extruded in beads for various packaging applications.
