1. Product Overview

UV Absorber UV-3030 is a high-molecular-weight cyanoacrylate UV light stabilizer. It features top-tier thermal stability and ultra-low volatility in the industry, and strongly absorbs UV light in the 280–320 nm range. Boasting excellent high-temperature resistance, it is suitable for polymer materials processed at high temperatures. It offers outstanding light transmittance and pale base color; its addition will not compromise the transparency or appearance color of finished products. The product resists migration and precipitation and delivers long-lasting weather resistance. It complies with food-contact systems. It is often compounded with hindered amine light stabilizers and antioxidants to synergistically improve UV aging resistance and yellowing resistance of high-temperature engineering plastics and high-end coatings. It is the preferred specialty additive for transparent articles processed at high temperatures.

4. Physical Properties and Solubility

This product is high-purity white crystalline powder. Its high-molecular-weight structure brings extremely low volatility and migration resistance, with high-temperature performance far superior to conventional benzotriazole UV absorbers. It has ultra-high light transmittance without base color contamination, ideal for high-end transparent products. At room temperature, it is readily soluble in organic solvents such as esters, ketones and aromatic hydrocarbons, slightly soluble in water. It can be uniformly dispersed in various high-temperature resin and coating systems. It has excellent chemical stability, acid and alkali resistance and aging resistance, and its performance does not degrade over long-term service.

5. Key Product Features

• Ultra-high temperature resistance & low volatility: Extremely good heat resistance, compatible with extrusion and injection molding above 300 ℃. Almost no volatilization or loss during processing, a dedicated additive for high-temperature processing. • Ultra-high light transmission & no discoloration: Visible light transmittance close to 100%, extremely pale base color, no adverse impact on the appearance texture of transparent and high-end light-colored products. • Migration & precipitation resistance: High-molecular-weight structure inhibits migration, prevents blooming and precipitation, ensuring long-term weather resistance and service life of finished parts. • High-end compliance: Meets FDA and EU food-contact requirements, applicable to food packaging and polymer articles in direct food contact. • Excellent compounding synergy: Works very well when blended with antioxidants and hindered amine light stabilizers, markedly improving yellowing resistance and outdoor exposure resistance of high-temperature materials.

6. Application Fields

Mainly used for high-temperature processed engineering plastics and high-end compliant products. Primarily compatible with high-temperature resins including PC, PET, PES, PA, ABS and PMMA. Widely applied in transparent engineering plastic components, food packaging materials, optical products, high-end transparent home appliance parts, high-temperature resistant automotive plastic components. Also suitable for high-end industrial baking varnishes, high-temperature resistant transparent coatings and functional coating systems. It effectively solves material yellowing, aging and loss of gloss caused by high-temperature processing and outdoor exposure.

7. Recommended Dosage

For general high-temperature plastics and coatings: 0.1%–0.4% (based on total weight of substrate). For high-transparency, food-contact and high-end articles under long-term outdoor exposure: 0.4%–0.6%. When compounded with hindered amine light stabilizers and composite antioxidants, the dosage may be appropriately reduced to balance protection performance and cost. Fine-tuning can be made according to formulation systems.

8. Application Method

It can be added at all processing stages including resin compounding, feeding for extrusion, injection molding and paint preparation. It supports direct feeding of dry powder or pre-dissolution and dispersion in organic solvents. Suitable for processing temperature ≤320 ℃ with stable performance under high-temperature conditions. Uniform dispersion can be achieved by normal stirring and compounding; no special modification process required.
