一般特征
Bayhydrol A 2470 is an aqueous hydroxyfunctional polyacrylic dispersion.
It is suitable for use in waterborne two-component polyurethane varnishes in combination with aliphatic polyisocyanates.

储存条件
Bayhydrol A 2470 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. 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 > 0º-30ºC.
