This product can be used in waterborne two-component polyurethane coatings in combination with waterdispersible polyisocyanate.

Storage Conditions

Bayhydrol A 2651 should be stored in tightly sealed original containers and protected from freezing, heat, and foreign materials. Short-time cooling down to -18°C does not typically damage the product. 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 greater than 0ºC-30ºC.
