Properties: VINNAPAS® 315 is designed for use as a base for high-speed packaging adhesives. It exhibits very high wet tack and high thickening response. Because of its poly(vinyl alcohol) stabilization and excellent mechanical stability, this dispersion has clean machining and can be used in a variety of roll, extruder or spray applications. The formaldehyde content of this dispersion is very low as it is manufactured with chemicals that do not generate formaldehyde. The dry VINNAPAS® 315 film is tack-free and heatsealable. The higher Tg gives the dried adhesive film both very high heat resistance and high tensile strength while maintaining greater flexibility than poly(vinyl acetate) films. The initial adhesive strength is excellent and maintains this strength even after aging. VINNAPAS® 315 exhibits good water resistance and excellent plasticizer migration.

Application: VINNAPAS® 315 is an excellent base for adhesive formulators and can be used in a wide variety of applications. Its rapid setting speed is useful in carton, case forming, and sealing applications. The natural affinity of the dispersion to coated stocks as well as kraft and its good water resistance make this dispersion suitable for bag seams, cups, tube winding, and high pressure laminates. It can also be used for application areas which include but are not limited to bookbinding, padding, laminations of leather to cloth and fiberglass to paper, craft glues, microwave packaging, and envelope back gums.
