Allgemeine Charakterisierung
Aqueous hydroxyfunctional polyacrylic dispersion, in combination with aliphatic polyisocyanates for waterborne 2K-polyurethane coatings.
Lagerungsbedingungen
- 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.
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 be expected. The viscosity can be adjusted 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.
