Chiguard® 460：High-Performance UVA Protection for Transparent Coatings
Tailored UV Absorber Solution for High-Transparency Coatings and Film Systems
In high-transparency and high-stability coating formulations, UV damage is often the critical factor that limits product lifespan. Chitec Technology introduces Chiguard® 460, a high-performance Hydroxyphenyl Triazine (HPT) UV absorber specifically engineered for superior UVA absorption with a maximum absorption wavelength at 348 nm. It delivers exceptional extinction efficiency and outstanding weathering resistance.
Whether used in ultra-thin film coatings or applications requiring maximum transparency, Chiguard® 460 provides strong UV protection, effectively extending product life and preserving color brilliance.
As a Hydroxyphenyl Triazine (HPT) UV absorber, Chiguard® 460 offers excellent light and thermal stability, making it ideal for high-temperature processes and harsh outdoor environments. Its chemically inert structure enhances resistance to acid rain, salt spray, and other environmental attacks. When combined with suitable resin systems and HALS (Hindered Amine Light Stabilizers), it contributes to outstanding weathering durability and acid resistance across the entire coating system.
Key Benefits of Chiguard® 460
- ✅ Targeted UVA Absorption： Long-Lasting Protection for Light-Sensitive Materials
- With peak absorption at 348 nm, Chiguard® 460 effectively blocks the UV-A range (320–380 nm), which is responsible for material discoloration and degradation.
- ✅ High Molar Extinction Coefficient： Effective in Ultra-Thin Films
- Thanks to its high molar extinction coefficient, it delivers superior UV shielding even at minimal loading levels.
- ✅ Excellent Anti-Yellowing Stability： Outstanding Thermal and Weathering Performance
- Chiguard® 460 endures high-temperature baking and outdoor exposure without decomposition or yellowing.
- ✅ Low Color Impact： Ideal for High-Transparency Systems
- Its light hue ensures minimal impact on color-sensitive coatings.
