Allgemeine Charakterisierung
Hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI).
As the hardener component for high-quality aqueous two-component polyurethane systems and as an additive to improve the property profile of aqueous coating and adhesive systems.
With respect to its composition, the product corresponds to the following sections of the U.S. FDA's guidlines "Title 21 CFR" : Section 175.105 "Adhesives".

Lagerungsbedingungen
- 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 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.
