一般特征

Aliphatic anionic polyurethane dispersion.
As a binder in the formulation of highly flexible water-thinnable coatings for wood, metal, plastics and mineral substrates. Also as a combination binder to improve the elasticity and flexibility of water-thinnable coatings.

储存条件

- Storage in original sealed Covestro containers.

-
Recommended storage temperature: 5 - 30 °C.

-
Protect from frost, heat and foreign material.

General information: An increase in viscosity may occur during storage. If the containers are not sealed properly, the evaporation of water will result in the formation of a film which cannot be redispersed. The product is sensitive to frost. Freezing will 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.
