General Characterization
Bayhydrol A 145 is a water-reducible, hydroxyfunctional polyacrylic dispersion.
It is suitable for use in combination with aliphatic polyisocyanates to formulate aqueous two-component clear- and topcoats for vehicle repair applications, heavy transport finishing and industrial coating.
It is also suitable for use in combination with amino resins or blocked polyisocyanates for waterborne, one-component, industrial baking coatings.

Storage Conditions
Bayhydrol A 145 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, but the viscosity may increase significantly. Prolonged freezing can damage the product irreversibly. 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. Recommended storage temperature is greater rthan 0º-30ºC.
