Covinax 370-00 is a pressure sensitive vinyl acrylic copolymer stabilized

Covinax 370-01


Covinax 370-01 is a hydroxyethyl cellulose stabilized vinyl acrylic copolymer which was designed for a variety of packaging applications, including window gums, laminating, bonding to printed or lacquered board, or bonding most synthetic films including untreated polyethylene. It exhibits very aggressive tack after drying. The cellulosic colloid, which is the primary stabilizer in Covinax 370-01, imparts a thixotropic rheology to the wet polymer. It also improves the water resistance of the dry film. Covinax 370-01 can be coated successfully on roll coaters, or it can be extruded in beads. Covinax 370-01 is FDA compliant under 21CFR 175.105.
