JADEWIN BP-2: The Expert in Broad-Spectrum UV Protection, Building a Strong Defense Against Aging for Materials

In the polymer materials, optical products, and coatings industries, UV-induced yellowing, cracking, and performance degradation have long been major challenges. As a broad-spectrum benzophenone-based UV absorber, JADEWIN BP-2 offers highly efficient absorption across the entire 260 nm–400 nm spectrum, covering the core UV-B to UVA range. It precisely addresses material photoaging challenges, making it the preferred light-stabilizing additive for high-end products.

I. Core Advantages: Broad-Spectrum Absorption, Exceptional Performance

JADEWIN BP-2 (Chemical Name: 2,2’,4,4’-tetrahydroxybenzophenone, CAS: 131-55-5) leverages its unique molecular structure to offer three core advantages: broad absorption, high stability, and strong compatibility:

✅ High-efficiency absorption across the full spectrum: Absorption extends into the UVA range, providing full coverage of UV radiation from 260 nm to 400 nm. The absorption peak reaches 345 nm, with an extinction coefficient of ≥580 (1%, 1 cm), effectively blocking UV damage across the entire spectrum.

✅ Excellent thermal stability and durability: With a melting point of 195–202°C, it exhibits outstanding thermal stability and is resistant to decomposition and volatilization during processing; it features low migration and resistance to extraction, ensuring minimal leaching over long-term use and maintaining protective performance over an extended period.

✅ Broad compatibility: Highly compatible with various polymer matrices, including linear polyester, CR-39 resin, alkyd resin, phenolic resin, and PUR systems, without affecting the transparency or mechanical properties of the final product.

✅ High Purity, Low Impurities: Appears as a yellow crystalline powder with a purity of ≥99.0% and volatile content of ≤0.5%. Batch consistency ensures compliance with high-end product manufacturing standards.

II. Diverse Applications: Comprehensive Coverage for Demanding Requirements

Optical Products

Custom-formulated for CR-39 resin lenses and linear polyester optical materials, it precisely meets UV absorption requirements in the 400 nm and below wavelength range. It effectively prevents lens yellowing and reduced light transmittance, enhancing optical stability and service life, making it the preferred additive for high-end optical lenses.

2. Resins and Synthetic Materials Sector

Compatible with alkyd resins, phenolic resins, and PUR systems, it is stably incorporated during polymer processing to inhibit UV-induced molecular chain degradation. It prevents material cracking, chalking, and color darkening, significantly improving the product’s weather resistance and anti-aging performance.

3. Coatings and Pigments

Used in oil-based coatings and fluorescent pigment systems, it protects coating resins from UV damage and extends the weather resistance of the coating. It also prevents UV-induced fading and brightness loss in fluorescent pigments, ensuring color stability and long-lasting gloss.

4. Other Polymer Dispersion Systems

Widely compatible with various polymer dispersion systems, it delivers excellent protective effects at an addition rate of just 0.1%–0.5%. With low addition costs and high cost-effectiveness, it balances performance and economy.

III. Value-Added Benefits: Beyond Protection, Cost Reduction and Efficiency Improvement

Extended Product Lifespan: Effectively delays photo-oxidative aging of materials, reducing replacement and maintenance costs, and is suitable for long-term outdoor use.

Ensured Quality Stability: High purity and low impurity levels prevent product defects caused by additive leaching, improving product yield and market competitiveness.

Simplified Production Process: Excellent compatibility with substrates allows for direct addition without additional modification steps, making it compatible with existing production lines and reducing production complexity.

IV. Summary

With its core advantages of broad-spectrum UV absorption (260nm–400nm), high stability, strong compatibility, and adaptability to diverse applications, JADEWIN BP-2 serves as an efficient UV protection solution for optical products, resins, coatings, and other fields. Whether for high-end CR-39 lenses or weather-resistant outdoor coatings, JADEWIN BP-2 builds a robust defense against aging for materials, helping to upgrade product quality and enhance value.
