Clariant AddWorks LXR 313 Light Stabilizer

Clariant AddWorks® LXR™ 313 is a synergistic blend of triazine UV absorber and low-molecular-weight HALS, engineered for the weathering requirements of high-performance paints and clear coatings. It combines broad-spectrum UV protection and free radical scavenging capabilities, and exhibits excellent compatibility in both solvent-based and waterborne coating systems.

Features Of Clariant AddWorks LXR 313 Light Stabilizer

  1. The triazine UV absorber covers a wide UV spectrum, efficiently shielding UV-A and UV-B rays, and reducing UV-induced coating damage from the source.

  2. Blended with low-molecular-weight HALS, it can scavenge free radicals generated by UV light, block the chain reaction of coating aging, and form a synergistic protection effect with UV absorbers.

  3. It has broad compatibility with both solvent-based and waterborne coating systems, without causing defects such as pinholes, haze or delamination, and is suitable for multi-formulation systems.

  4. Optimized for clear coatings, it does not affect the light transmittance and clarity of coatings after addition, ensuring the appearance quality of high-gloss and high-transparency coatings.

  5. It has good extraction resistance and migration resistance; protective components are not easy to be lost with rainwater or cleaning agents, maintaining long-term coating weathering performance

Typical Applications Of Clariant AddWorks LXR 313 Light Stabilizer

  1. Suitable for solvent-based high-performance industrial topcoats, such as coatings for construction machinery and containers, improving the anti-aging ability of coatings for outdoor service.

  2. Compatible with waterborne architectural exterior wall clear topcoats, providing dual protection against UV rays and acid rain for wall decorative layers, extending the renovation cycle.

  3. Applicable to automotive refinish clear coats, ensuring that the weather resistance of repaired areas is consistent with that of original factory paint surfaces, avoiding color difference and gloss loss.

  4. Used in high-gloss clear coatings for wooden furniture, preventing fading of wood substrates caused by UV radiation and protecting coatings from yellowing.

  5. Suitable for coatings dedicated to plastic substrates, such as coatings for ABS and PC casings, improving the synergistic weathering stability of coatings and substrates.
