VINNAPAS® 400 H

VINNAPAS® 400 H by Wacker is poly(vinyl alcohol) stabilized vinyl acetate-ethylene copolymer dispersion. It offers a superior balance of adhesive/cohesive properties useful in achieving much higher formulation viscosities. 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 backbone of the polymer gives the dried adhesive film both high tensile strength and flexibility that continue to be present even with fluctuations in temperature and humidity. Exhibits excellent heat resistance. The initial adhesive strength is excellent even after aging, and it exhibits excellent resistance to plasticizer migration. Applications of VINNAPAS® 400 H include packaging (case and carton), bookbinding, textile bonding, vinyl and paper to wood laminating, automotive applications, and craft glues. The ethylene in the polymer acts as an internal plasticizer which provides flexibility and reduces or eliminates the need for plasticizer in many applications. It forms strong bonds between porous substrates and such films as poly(vinyl chloride) (PVC), poly(vinylidene chloride), cellulose acetate, cellophane and acrylic. It adheres to widely diversified substrates such as paper, wood, cotton cloth, nylon cloth, glass and glass fibers, hardboard, urethane foam and clay coated paperboard. VINNAPAS® 400 H has a shelf life of 9 months.
