Covestro Bayhydrol® XP 2637 Polyurethane Coating
Categories: Polymer; Thermoplastic; Adhesives, Sealants, and Coatings; Thermoset; Polyurethane, TS

Material Notes: Bayhydrol XP 2637 is a an ionic/non-ionic polycarbonate ester polyurethane dispersion. Bayhydrol XP 2637 is a solvent-free polyurethane dispersion which can be used to formulate coatings that harden at room temperature or baking coatings. It allows coating of a wide variety of substrates ranging from hard ones to flexible ones such as leather, textiles, plastics and metals. Coatings formulated with Bayhydrol XP 2637 exhibit high scratch resistance and lightfastness. Other benefits of Bayhydrol XP 2637 are good aging stability and very good hydrolysis resistance.

Properties / Applications: Bayhydrol XP 2637 is a solvent free polyurethane dispersion that can be used in the formulation of ambient-cure or bake coatings for a wide range of rigid and flexible substrates such as leather, vinyl- coated fabric, textiles, plastics and metals. Bayhydrol XP 2637 exhibits a combination of flexibility, good water and solvent resistance, outstanding hydrolytic stability and may be blended with other polyurethane dispersion to achieve intermediate properties. As with any product, use of Bayhydrol XP 2637 in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
