BAYHYDROL U 2750 is an aliphatic, hydroxyfunctional polycarbonate ester-polyurethane dispersion from Covestro. It can be thinned with water to application viscosity. BAYHYDROL U 2750 when combined with hydrophobic or hydrophilic polyisocyanates forms high-performance, hard-elastic two-component polyurethane coatings. These coatings provide very good weathering resistance, hardness, elasticity and scratch resistance important for exterior applications. BAYHYDROL U 2750 based coatings also deliver good adhesion to plastics materials commonly used in construction. It allows formulating durable, flexible and protective coatings suitable for applications requiring scratch and weather resistance.
