Low-viscosity, aliphatic polyisocyanate resin based on hexamethylene diisocyanate.
As the hardener for weather-stable coating systems.
Logistics and Handling:
Storage Conditions
– Storage in original sealed Covestro container.
– Recommended storage temperature: 0 – 30 °C.
– Protect from moisture, heat and foreign material.
General information: 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.
