储存条件
Bayhydrol A 2227/1 should be stored in tightly sealed original containers and protected from freezing, heat, and foreign materials. This product is sensitive to freezing. 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 greater than 0º-23ºC.
