Features and Advantages
- Developed specially for high performance coating applications
- Broadband absorption provides efficient protection to coatings and light sensitive substrates
- Excellent solubility and high thermal and environmental permanence
Product Application
TP-SORB UV-928 has a relatively wide absorption characteristic and can effectively protect coatings and other photosensitive materials. It features high solubility, good high-temperature resistance and environmental durability, etc. It is suitable for high-performance coatings, especially for powder coatings and continuous coatings for rolls, and can also be used in automotive coatings and conventional coatings. Generally, the effect is better when the light stabilizer UV292 or UV-123 is used together. Store it away from sunlight, high light, moisture, and avoid light stabilizers containing sulfur or halogen elements.
Safety and protection
The package is 180kg/ barrel, which can be customized. No special safety equipment is required, according to the general chemicals cool, dry, ventilated storage, away from fire, heat sources, strong oxidants, strong reducing agents.
