General Characterization
Bayhydur XP 2759 is a hydrophillic aliphatic polyisocyanate based on isophorone diisocyanate (IPDI).
It is used as a hardener for waterborne two-component polyurethane systems.
It is used as a hardener for waterborne two-component polyurethane systems.
Storage Conditions
Bayhydur XP 2759 should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. The product is sensitive to moisture. Storage at higher temperatures will result in increase of color and viscosity. Storage at significant lower temperatures will result in solidification. This solidification is reversible by briefly heating the product without adversely affecting the quality of the product. Recommended storage temperature is 0º-30ºC.
