一般特征

Bayhydrol UV 2689/1 is an anionic, UV-curable polyurethane dispersion.
Bayhydrol UV 2689/1 is used in the formulation of industrial waterborne UV clear and pigmented coatings. Main applications are plastic coatings (e.g mobile phones) and wood coatings.
Before UV curing the surface of dried films is soft and slightly tacky. After UV-cure the coatings are hard with high chemical and mechanical resistance.
The product is suitable to achieve high gloss coatings.

储存条件

Bayhydrol UV 2689/1 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.
