General Characterization

Bayhydrol UH 2305 is an aliphatic, anionic/non-ionic polyester-polyurethane dispersion.
It is a shear-stable combination binder used in the formulation of flexible two-component polyurethane top coats with pleasant handle, e.g. soft-feel systems.

Storage Conditions

Bayhydrol UH 2305 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. If the containers are not sealed properly, the water will evaporate to form a non-redispersible film. Recommended storage temperature
is > 0º-30ºC.
