General Characterization
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.

Storage Conditions
- Storage in original sealed Covestro container.
- Recommended storage temperature: 5 - 30 °C.
- Protect from frost, intense radiation (light, UV), heat and foreign material.
General information: The product is sensitive to frost. 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. Even though the product is stabilized by a biocide, contamination with certain bacteria, fungi or algae may render the product unusable.
