Sunny Chemical UV-326
UV-326 is a benzotriazole type UV absorber. It offers superior light protection of polyolefin substrates against the deterioration of UV radiation. It is also efficient for the light stabilization of polyvinyl chloride, unsaturated polyurethane, styrenic polymers, coatings and lacquers.
Advantage:
- Very high photostability for its strong ability to absorb light especially in UV region (290-400 nm)
- Odorless, does not bring smells to the polymers
- High resistance to thermal degradation
- Low vapor pressure, very little or no loss during processing.
Applications:
- Styrenic polymers: 0.2-0.5 wt% for PS based on polymer weight.
- Polyvinyl chloride: 0.2-0.5 wt% for PVC based on polymer wt.
- Polypropylene: 0.3-0.6 wt% for PS based on polymer weight.
- Coatings and lacquers: 0.5-1.0% for nitrocellulose based on polymer weight.
- Unsaturated polyester: 0.2-0.4 wt% for PS based on polymer wt.
