General Characterization

Bayhydrol UH 2648/1 is an aliphatic, polyester-polycarbonate based anionic polyurethane dispersion, solvent free.
It is typically used as a binder for the formulation of water-thinnable one component and two component coatings for different substrates, especially plastic substrates. It is well suited for metallic coating systems, fillers and top coats.

Storage Conditions

Bayhydrol UH 2648/1 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. Recommended storage temperature is > 0º- 40ºC.
