Applications of 131-56-6
| Industry | Application | Processing |
|---|---|---|
| Plastics Industry | UV absorber for polypropylene, polyethylene, polyvinyl chloride, and other plastic products to prevent photodegradation | Blended with the resin prior to polymer melt extrusion or injection molding at a dosage of 0.1–0.5 wt% |
| Coatings & Inks | Photostabilizer to enhance weather resistance and anti-yellowing performance of automotive coatings, wood coatings, and industrial protective coatings | Incorporated during the grinding and dispersion stage of coating formulation, used synergistically with titanium dioxide and resin systems |
| Cosmetics | Sunscreen agent (UV-B absorber) for personal care products including sunscreens, lipsticks, and lotions | Dissolved in the oil phase, then homogenized into the emulsification system; final concentration typically ranges from 0.5–5.0% (w/w), compliant with cosmetic regulatory limits in respective jurisdictions |
| Adhesives | Enhances UV stability to prevent aging and embrittlement of adhesive layers | Added during adhesive compounding into acrylic or polyurethane adhesive systems at a dosage of 0.2–1.0% |
| Synthetic Fibers | Spinning additive for synthetic fibers such as polyester and nylon to impart UV resistance | Introduced as masterbatch (10–20% concentration) into chips, followed by melt spinning to produce functional fibers |
