【Usage】
UV-326, a light stabilizer, is a benzotriazole based ultraviolet absorber that enhances the absorption of long wavelength ultraviolet light
【Introduction】
UV-326 is a high-performance light stabilizer that belongs to the benzotriazole family of ultraviolet absorbers. It is specifically designed to enhance the absorption of long-wavelength ultraviolet (UV) light, providing excellent protection against UV-induced degradation.
Key Features
- Broad UV Absorption Range: UV-326 effectively absorbs UV radiation in the 270-380 nm wavelength range. This broad absorption spectrum makes it suitable for protecting a wide variety of materials from UV damage.
- High Thermal Stability: The product exhibits good thermal stability at high temperatures, making it ideal for use in applications involving high-temperature processing.
- Low Volatility: UV-326 has low volatility, ensuring that it remains effective even under prolonged exposure to heat.
- Non-Toxic and Low Odor: It is characterized by low toxicity and minimal odor, making it safe for use in various applications, including those involving food contact.
Applications
UV-326 is widely used across multiple industries due to its versatile properties:
- Plastics: It is commonly used in polyolefins, polyvinyl chloride (PVC), polystyrene, polyamides, and ABS resins. It helps prevent discoloration, brittleness, and other forms of UV-induced degradation in these materials.
- Coatings and Paints: UV-326 is added to coatings and paints to enhance their resistance to UV light, thereby extending the service life of painted surfaces.
- Rubber: It is also used in synthetic rubber to improve its light stability.
- Food Packaging: Due to its non-toxic nature, UV-326 is approved for use in food-grade plastic products.
Benefits
- Enhanced Durability: By absorbing UV light, UV-326 significantly reduces the rate of photo-oxidative degradation, thereby enhancing the durability and service life of materials.
- Color Stability: It helps maintain the original color of materials by preventing UV-induced discoloration.
- Versatility: UV-326 can be easily incorporated into various polymer formulations without compromising their processing characteristics.
Conclusion
UV-326 is a highly effective benzotriazole-based UV absorber that offers robust protection against UV-induced degradation. Its broad absorption range, thermal stability, low volatility, and non-toxic nature make it a preferred choice for enhancing the light stability of plastics, coatings, and other materials. Whether used in industrial applications or consumer products, UV-326 ensures that materials remain durable and visually appealing over an extended period.
