Hauthane HD-2504

A very hard, polycarbonate-based, aliphatic, waterborne polyurethane dispersion. HD-2504 was developed for general coatings use where exceptional resistance to hydrolysis, oxidation and UV degradation is required. HD-2504 is ideally suited for exterior applications where film durability and longevity are important considerations. Possesses superior chemical and stain resistance. Also has excellent exterior weathering durability and humidity resistance. Contains n-methyl pyrrolidone co-solvent. HD-2504 may be used as a sole vehicle or blended with acrylic emulsions for application by conventional or air-assisted spray equipment. It may be thickened with associative thickeners to attain desired application viscosity.
