KURARAY POVAL™ 2-98

KURARAY POVAL™ 2-98 by Kuraray is polyvinyl alcohol (PVOH) grade. It is a water-soluble polymer manufactured by alcoholysis of polyvinyl acetate. It is notable for its good bonding strength and pigment binding capacity because PVAs have such good cohesion and good adhesion to fibers, fillers as well as pigments. It features excellent film forming characteristics, high tensile strength and elasticity, as well as resistance against organic solvents and dispersing power. For the modification of aqueous adhesives its aqueous solution can be added to polymer emulsions already stabilized with polyvinyl alcohol which affects the extension of the open time, increase of the setting speed and influence on the rheology. KURARAY POVAL™ 2-98 is used in adhesives which are employed mainly in the paper processing industry.
