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.

On the basis of the given intrinsic product properties and the respective circumstances during storage the product may show a slight film formation also in the original packaging. Pre-filtration of the material before use is recommended.
