General Characterization
Aqueous polyurethane dispersion. Dispercoll® U 2662 is a waterborne dispersion of an anionically modified polyurethane. It is an adhesive raw material for the formulation of adhesives for use in e.g. the shoe, furniture, or automotive industries. Its characteristic polymer properties make Dispercoll® U 2662 particularly well suited for heat-activated bonding applications with high tack and good hydrolysis resistance.
