VINNAPAS® EP 760
Dispersions
VINNAPAS® EP 760 is a unique, rapid-setting vinyl acetate-ethylene
copolymer. It is not simply a high-solids version of VINNAPAS® EP series dispersion, but a polymer that has outstanding adhesion to very difficult-to-bond substrates including polyester, poly(ethylene terephthalate), tempered aluminum foil and polystyrene. The dispersion combines very high-solids content with a low viscosity — a combination that permits
the addition of very high filler loadings, resulting in adhesive formulations with solid contents as high as 80 percent, or even greater. The dispersion will not thicken excessively on the addition of plasticizers that also allows for the formulating of very high-solids adhesives. VINNAPAS® EP 760 is very shear stable, which means that it can be applied on high-speed packaging machines using roll, extrusion or spray equipment. The dispersion dries to a slightly tacky, clear, water-resistant film.
