Features Of Clariant AddWorks ATR 945 B Light Stabilizer

  1. High-performance hindered amine light stabilizer (HALS) with low volatility and excellent thermal stability.

  2. Optimized for thin-section and outdoor applications requiring long-term UV resistance without surface blooming.

  3. Compatible with polyolefins, engineering plastics, and thermoplastic elastomers—enabling broad formulation flexibility.

  4. Low extractability and high migration resistance, supporting compliance with food-contact and automotive interior standards.

  5. Enhances retention of mechanical properties and color stability under intense UV and weathering exposure.

Typical Applications Of Clariant AddWorks ATR 945 B Light Stabilizer

  1. Automotive exterior trim and under-hood components exposed to sunlight and elevated temperatures.

  2. Outdoor consumer goods including garden furniture, playground equipment, and residential siding.

  3. Thin-gauge packaging films and agricultural mulch films requiring extended UV durability.

  4. Technical profiles and pipes used in infrastructure and irrigation systems.

  5. Recycled polyolefin compounds where stabilization must compensate for polymer degradation history.
