CYASORB CYNERGY SOLUTIONS® B877 is an additive designed to protect polymers against UV light degradation in building and construction applications such as composite roofing tiles and shakes, polymer siding, solar shingles (BIPV), plastic trim, doors, shutters, window frames and stadium seats. B877 provides long-term UV light protection to polymers such as polyethylene (PE), polypropylene (PP) and thermoplastic olefin (TPO). The product is a non-blooming stabilizer that extends the lifespan of polymeric applications by preserving their physical and surface properties. For example, it helps prevent microcrack formation and provides excellent color and gloss retention. Additionally, B877 does not interfere with other system components, such as pigments and fillers, and can be combined with antioxidants to increase thermal stability.
