1. Industrial Coatings:
Suitable for both solvent-based and water-based industrial coatings, it effectively prevents problems such as gloss reduction, cracking, spotting, chalking, and surface peeling caused by UV radiation, extending the service life of coatings in outdoor environments.
2. Automotive Coatings:
It meets the high weather resistance requirements of automotive coatings and, when used in combination with hindered amine light stabilizers (such as HALS 292, HALS 123, etc.), synergistically inhibits phenomena such as gloss loss, cracking, blistering, discoloration, and peeling of automotive coatings.
3. Wood Coatings:
Used in water-based and oil-based wood coatings, it protects the wood substrate from UV damage, preventing problems such as fading and cracking of the wood surface, and extending the appearance retention time of wood products.
4. Plastics and Polyurethane Coatings:
It can be added to plastics and polyurethane-related coatings to enhance the weather resistance of the coating, preventing aging of plastics and polyurethane materials due to light exposure, and maintaining their physical properties and appearance stability.
5. Other Liquid Systems:
Due to its easy emulsification, high temperature resistance, and anti-extraction properties, it can also be used in other liquid systems requiring UV aging resistance, such as some adhesives and sealants, to improve the weather resistance of the products.
