一般特征

Bayhydrol A 2457 is an anionic polyacrylic dispersion.
It is suitable as a binder in the formulation of water-reducible two-component coatings and sealers for mineral substrates and reactive resins (EP, PU).

储存条件

Bayhydrol A 2457 should be stored in tightly sealed original containers and protected from freezing, heat, and foreign materials. Short-time cooling down to -18ºC 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. Recommended storage temperature is > 0º-30ºC.
