Covestro Bayhydrol® U XP 2757 Polyurethane Coating
Categories: Polymer; Thermoplastic; Adhesives, Sealants, and Coatings; Thermoset; Polyurethane, TS

Material Notes: Bayhydrol U XP 2757 is an aliphatic, hydroxyl-functional polycarbonate ester-polyurethane dispersion, cosolvent-free. It is suitable as a binder for water-reducible two component polyurethane coatings, especially soft-touch and comfort coatings.

Properties / Applications: Bayhydrol U 2757 can be used in combination with flexible polyurethane dispersions, e.g. Bayhydrol UH 340/1, UH 650, UH 2305 and UH XP 2660 to formulate soft-touch coatings. In combination with polyacrylates, e.g. Bayhydrol A 2058 highly chemical resistant comfort coatings can be formulated. Suitable polyisocyanate components are e.g. Bayhydur® 302, 304, XP 2655 and also Desmodur® N 3600 and N 3900. Bayhydrol U 2757 is cosolvent-free. It can be used in the formulation of highly haptic soft-feel coatings. The product has high elasticity, good chemical resistance and good scratch resistance. As with any product, use of Bayhydrol U XP 2757 in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
