BLS® 5411 is a benzotriazole type ultraviolet light absorber (UVA), imparting good light stability for plastics and other organic polymers. BLS® 5411 protects polymers as well as organic pigments from UV radiation helping to preserve the original appearance and physical integrity of polymeric systems; particularly in polyesters, polyvinyl chlorides, styrenics, acrylics, polycarbonates and polyvinyl butyral during outdoor weathering.

Applications: BLS® 5411 light stabilizer is effective for a broad range of UV absorption. In addition, it is also noted for its low color contribution, low volatility and excellent solubility. BLS® 5411 also provides ultraviolet protection in a wide variety of polymeric systems; particularly in polyesters, polyvinyl chlorides, styrenics, acrylics, polycarbonates and polyvinyl butyral during outdoor weathering. Typical end use applications include molded items, extruded sheets, glazing materials for window lighting, signs, marine and auto applications. Specialty applications for BLS® 5411 include coatings (particularly thermo sets where low volatility is a concern), photographic products, sealants, and elastomeric materials.

Advantages:

• Strong absorption of ultraviolet radiation in the 300-400 nm region

• High degree of photostability

• Low volatility

• Low color contribution

• Excellent solubility
