General Characterization
Bayhydur ultra 401-70 MPA/X is a hydrophilically modified aliphatic polyisocyanate based on isophorone diisocyanate (IPDI).
As the co-reactant for aqueous resins and as the hardener for chemically resistant and weather-stable coating systems.

Storage Conditions
Bayhydur ultra 401-70 MPA/X 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.
