General Characterization

Bayhydrol A 2601 is water-reducible, hydroxyfunctional polyacrylate dispersion.
It can be used in combination with aliphatic polyisocyanates for the formulation of waterborne two-component clearcoats and topcoats for general industrial and transportation coatings. It can also be used in combination with suitable melamine resins for the formulation of one-component coatings.

Storage Conditions

Bayhydrol A 2601 should be stored in tightly sealed original containers and protected from freezing, heat, and foreign materials. 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.
Recommended storage temperature is greater than 0ºC-30ºC.
