General Characterization
Bayhydrol UH 650 is a solvent-free, aliphatic polyurethane resin dispersion in water.
It is suitable as a binder for waterborne, air- and oven-drying base coats in two-coat systems for the coating of plastics and as a combination binder for soft-touch coatings.

Storage Conditions
Bayhydrol UH 650 should be stored in tightly sealed original containers and protected from freezing, heat, and foreign materials. Because slight sedimentation may occur during storage, homogonize thoroughly (e.g. by stirring) prior to removing product. If the containers are not kept well closed, a non-redispersible film is formed as a result of the evaporation of water. The product is sensitive to freezing. Freezing will 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 5º-30ºC.
