Lagerungsbedingungen
- Storage in original sealed Covestro containers.
- Recommended storage temperature: 5 - 30 °C.
- Protect from frost, heat and foreign material.
General information: The product is sensitive to frost. Prologed freezin can damage the product irreversibly. Prolonged storage at higher temperatures may result in a decrease of viskosity and/or an increase of average particle size, possibly resulting in sedimentation of coagulation.
The viscosity of the product is largely governed by the pH. As the pH may decrease during storage, a decrease in viscosity is also to e expected. The viscosity can be restored to its original value by the addition of small amounts of an aqueous 10 % solution of dimethyl ethanol amine.
Contamination with certain bacteria, fungi or algae may render the product unusable.
