General Characterization

Bayhydrol UV 2280 is a urethane acrylate dispersion.
It is used in the formulation of aqueous UV-curing coatings. Due to its very good initial physical drying, it is particularly suitable for use in aqueous pigmented UV-curing coatings.

Storage Conditions

Bayhydrol UV 2280 should be stored in tightly sealed original containers and protected from freezing, intense radiation (light, UV), heat, and foreign materials. The product is sensitive to freezing. Freezing will damage the product irreversibly. Prolonged storage at higher temperatures may result in an increase of average particle size, risk of sedimentation, risk of pH-drift and ultimately coagulation. Recommended storage temperature is 5º-30ºC.
