General Characterization

Hydrophilically modified aliphatic polyisocyanate based on isophorone diisocyanate (IPDI).
Bayhydur® 401-60 PGDA might be used as co-reactant for aqueous resins and as hardener for chemically resistant and weather-stable coating systems.

Storage Conditions

- Storage in original sealed Covestro container.

- Recommended storage temperature: 0 - 30 °C.

- Protect from moisture, heat and foreign material.

General information: Hydrophilic isocyanates are very moisture-sensitive and react with water to form carbon dioxide and insoluble urea. Containers must always be kept tightly closed. Contact with water in all forms (moist air, solvents, moist containers) must be avoided, because of generation of carbon dioxide and the dangerous increases of pressure. Storage at higher temperatures will result in increase of color and viscosity.
