一般特征

Self-crosslinking urethane acrylate dispersion.
Self-crosslinking UV curing polyurethane dispersion that shows very fast water release and high chemical and mechanical resistance, even under mild UV curing conditions. Product can be used even without UV curing or reduced amount of photoinitiator.

储存条件

- Storage in original sealed Covestro container.

- Recommended storage temperature: 5 - 30 °C.

- Protect from intense radiation (light, UV), frost, 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.
