General Characterization

Anionic, UV-curable polyurethane dispersion.
Bayhydrol® UV 2720/1 is used for the formulation of waterborne UV coatings for industrial coating of plastics and wood and other substrates, particularly suitable for pigmented systems. As a thermoformable product it is an ideal solution for postformable 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.
