How To Use Water-based UV Stabilizer Coating Dec 07, 2016

In addition to high efficiency, UV stabilizers must meet some basic but most important requirements. In order to achieve this high efficiency, complete compatibility, UV stabilizers must have excellent solubility in the film-forming base. This requires both high performance and low volatility, especially for baking. With these properties, there can be no side effects such as discoloration, reaction with other components in the coating, or cross-linking.

The UV stabilizer must be water-repellent for obvious reasons. Stabilizers can easily be extracted from the coating because of settling, condensation, moisture, or other moisture-producing conditions. However, in water-based systems, the use of hydrophobic UV stabilizer is indeed more difficult.
