General Characterization
Bayhydur XP 2655 is a hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI).
It is suitable as a hardener for waterborne two-component polyurethane systems.
It is suitable as a hardener for waterborne two-component polyurethane systems.
Storage Conditions
Bayhydur XP 2655 should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. Hydrophilic isocyanates are very moisture-sensitive and react with water to form carbon dioxide and insoluble ureas. The containers must always be kept tightly closed. The access of water in all forms (moist air, solvents, moist containers) must be prevented, because the generation of carbon dioxide can lead to dangerous increases in pressure. Storage at higher temperatures will result in increase of color and viscosity.Recommended storage temperature is 0º-30ºC.
