General Characterization

Bayhydrol UH 2660/1 is an anionic aliphatic polyester-polyurethane dispersion, cosolvent-free.
It is suitable for use as a combination binder for the formulation of water-reducible soft-feel coatings.

Storage Conditions

Bayhydrol UH 2660/1 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. The containers must be well closed to prevent the evaporation of water which may result in the formation of a non-redispersible film. Recommended storage temperature is greater than 0ºC-40ºC.
