General Characterization

Water-reducible, hydroxyfunctional polyacrylic dispersion
In combination with aliphatic polyisocyanates to formulate aqueous two-component clear-, topcoats, primer and filler for heavy transport finishing, industrial coating, plastic and wood applications.
In combination with amino resins or blocked polyisocyanates for waterborne one-component industrial baking coatings.

Storage Conditions

- Storage in original sealed Covestro container.

- Recommended storage temperature: > 0 - 30 °C.

- Protect from frost, heat and foreign material.

General information: 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 restored to its original value by the addition of small amounts of an aqueous 10 % solution of dimethylethanolamine. 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.
