Tungsten trioxide contributing to improved weather resistance for coatings.
Enhance the weather resistance of coatings! High purity, China-free tungsten trioxide.
In the paint industry, there is a demand for products that can withstand outdoor use. In particular, for paints exposed to ultraviolet rays and rain, weather resistance is a crucial factor that affects the lifespan and quality of the product. Low weather resistance can lead to deterioration, discoloration, and peeling of the paint film, potentially diminishing the product's value. Our tungsten trioxide contributes to improving the weather resistance of paints and supports the long-term quality retention of products. 【Usage Scenarios】 - Outdoor paints - Automotive paints - Architectural paints 【Benefits of Implementation】 - Suppression of paint film deterioration - Prevention of discoloration and fading - Improvement of product durability
