Protect from frost, heat and foreign material.

General information: The product is sensitive to frost. 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.
The containers must be well closed to prevent the evaporation of water which may result in the formation of a non-redispersible film.
Contamination with certain bacteria, fungi or algae may render the product unusable.
