Storage Conditions
- Storage in original sealed Covestro containers.
- Recommended storage temperature: > 0 ≤ 30 °C.
- Protect from frost, heat and foreign material.
General information: Short-time cooling down to -18 °C does not typically damage the product. Prolonged freezing can damage the product irreversibly. Prolonged storage at higher temperatures may result in a decrease of viscosity and/or an increase of average particle size, possibly resulting in sedimentation or coagulation.
Contamination with certain bacteria, fungi or algae may render the product unusable.
