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. Due to the raw materials used, the product can occasionally exhibit temperature-dependent turbidity. This turbidity can be reversed by thinning with solvents or heating carefully to max. 50 °C without adversely affecting the quality of the product.
