BAYHYDUR ULTRA 2759 is a hydrophilic aliphatic polyisocyanate based on isophorone diisocyanate (IPDI). It is used as a co-reactant for aqueous binders. BAYHYDUR ULTRA 2759 can be easily emulsified in the aqueous phase due to its hydrophilic character. This allows it to be used as a hardener for waterborne two-component systems. Coatings made using BAYHYDUR ULTRA 2759 exhibit high chemical and weather resistance making it suitable for applications requiring durability. BAYHYDUR ULTRA 2759 can be combined with other polyisocyanates to reduce drying times, increase hardness, weather resistance and open time. This makes it a versatile option for formulations in industries that require protective and decorative coatings with outstanding performance.
