VINAPUR® 4702 is an aqueous dispersion of an acrylic/urethane polymer, suitable as a binder for the formulation of water-resistant roofing, terrace, and waterproofing membranes.
The main properties that characterize VINAPUR® 4702 and its different uses are excellent adhesion, high resistance to water even in stagnant conditions, excellent flexibility even at low temperatures, and resistance to dirt pick-up.
The polyurethane component imparts higher water resistance, high flexibility even at low temperatures and no dimensional change of the film immersed in water. The acrylic component improves mechanical properties, resistance to dirt setting and rheological behavior.
