BAYHYDUR ULTRA 308

BAYHYDUR ULTRA 308 is a hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI). It is used as a hardener for waterborne two-component coatings, top coats, sealers and as an additive to enhance the property profile. BAYHYDUR ULTRA 308 can be easily emulsified in the aqueous phase and used as the crosslinking agent for aqueous polyol binders. It can also be added to conventional OH-free dispersions to improve their property profiles. BAYHYDUR ULTRA 308 provides benefits like improved mechanical strength, chemical resistance and durability to the applied materials. Its hydrophilic character allows for easy mixing with water-based formulations and provides an environment-friendly option for various applications in the building industry.
