一般特征
Bayhydrol UH 2557 is an aliphatic, fatty acid-modified, anionic polyurethane dispersion.
It is suitable as a binder for the formulation of water-reducible coatings and sealers for wood and wood materials.
It is suitable as a binder for the formulation of water-reducible coatings and sealers for wood and wood materials.
储存条件
Bayhydrol UH 2557 should be stored in tightly sealed original containers and protected from freezing, heat, and foreign materials. The 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 > 0º-30ºC.
