VINNAPAS® 400 H is used as a base for adhesives and offers a superior balance of adhesive/ cohesive properties. Much higher formulation viscosities can be achieved due to the higher viscosity of the dispersion. This allows for more dilution water to be added to achieve the same end viscosity and thus reduce overall costs. This dispersion exhibits excellent setting speed, wet tack, and high thickening response. It has clean machining and is suitable for a variety of roll, extruder or spray applications because of its poly(vinyl alcohol) stabilization. The dry film is tack-free and heat-sealable. Just like VINNAPAS® 400, this dispersion has excellent heat resistance which, is much greater than that exhibited by other vinyl acetate-ethylene, vinyl acetate-maleate and vinyl acetate-acrylate copolymers with similar glass transition temperatures VINNAPAS® 400 H exhibits excellent resistance to plasticizer migration.
