VINNAPAS 920

VINNAPAS® 920 offers improved adhesion properties over conventional plasticized VAE copolymer dispersions due to a unique polymerization process that combines high ethylene content and carboxyl functionality into the backbone of the polymer. The stabilization of this dispersion with poly(vinyl alcohol) provides high wet tack, good setting speed, and good machinability. The carboxylic acid functionality provides crosslinking sites and a route for the dispersion to be thickened as the pH is increased. The dried film of this dispersion exhibits residual dry tack and greater flexibility due to the low Tg. Its excellent film coalescence offers good film clarity, water resistance and green strength over conventional VAE's. The low Tg of the dispersion provides greater flexibility, adhesion and dry tack than conventional VAE's.
