BAYHYDUR 2547 is a hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI). It is used as a crosslinking agent for waterborne polyol binders. BAYHYDUR 2547 provides excellent dispersion stability in aqueous systems due to its hydrophilic character. This allows for easy incorporation into water-based coating formulations. As a hardener for two-component waterborne coatings, BAYHYDUR 2547 offers benefits like improved mechanical properties, chemical resistance and durability of the final coating. Its dispersion stability and reactivity make it suitable for applications that require high performance protective and decorative coatings with low environmental impact.
