SOLVAY CYASORB CYNERGY SOLUTIONS® B877 is a non-blooming composite UV stabilizer for construction, designed for polyolefins. It resists long-term UV degradation, prevents gloss loss, discoloration and microcracks, is compatible with pigments/fillers, enhances thermal stability with antioxidants, and extends outdoor service life of building materials.
Non-blooming formula design, no precipitation or whitening during use, ensuring long-term stability of building materials’ surface appearance and protective performance.
Excellent weather resistance, effectively inhibiting UV-induced microcracks, gloss reduction and discoloration, suitable for long-term outdoor exposure scenarios.
Superior compatibility with polyolefin substrates like PE, PP, TPO and various pigments/fillers, without interfering with subsequent coating, sealing and other processes.
Can be used synergistically with antioxidants to simultaneously enhance light and thermal stability, improving materials’ comprehensive anti-aging protection capability.
Compliant with building material environmental standards, suitable for high-end applications with strict weather resistance requirements such as BIPV roofing and exterior siding.
BIPV roofing tiles and solar backsheets, resistant to long-term sunlight and rain, ensuring stable mechanical properties and appearance of materials, meeting weather resistance requirements of more than 25 years.
Polyolefin exterior siding, shutters and window frames, preventing UV-induced aging and embrittlement, extending component service life and maintaining consistent building appearance.
Composite roofing tiles and outdoor stadium seats and other municipal building materials, withstanding extreme climates and frequent use, reducing maintenance costs and improving product cost-effectiveness.
TPO roofing membranes and geomembranes, suitable for building waterproofing and anti-seepage projects, balancing weather resistance and construction convenience, ensuring long-term engineering reliability.
Plastic decorative trims and door/window accessories, enhancing outdoor weather resistance, avoiding cracking and discoloration during use, and suitable for various architectural styles.
