Clariant Hostavin ARO 8 P Light Stabilizer

Clariant Hostavin® ARO 8 P is a hydroxy-benzophenone UV absorber in the form of pale yellow crystalline powder. It is suitable for coatings and various plastics, capable of converting UV radiation into heat, featuring high cost-effectiveness and being certified for food-contact plastics in multiple countries.

Features Of Clariant Hostavin ARO 8 P Light Stabilizer

  1. Based on hydroxy-benzophenone, it achieves protection by physically converting UV radiation into heat, effectively delaying substrate aging and degradation.

  2. In pale yellow crystalline powder form, it has good solubility in most organic solvents, insoluble in water, compatible with solvent-based coating formulations.

  3. Excellent thermal stability, not easy to decompose during processing, adaptable to conventional production processes of plastics and coatings.

  4. High cost-effectiveness, suitable for scenarios with low to medium weathering stability requirements, and can enhance protection when used synergistically with HALS.

  5. Widely certified for food-contact plastics, applicable to food-related plastic packaging and other applications with high compliance requirements.

Typical Applications Of Clariant Hostavin ARO 8 P Light Stabilizer

  1. Suitable for solvent-based wood coatings, providing UV fading and aging resistance protection for indoor and outdoor wood coatings, ensuring long-lasting coating gloss and appearance.

  2. Compatible with general plastics such as polyethylene, polypropylene, and polyvinyl chloride, improving the outdoor weather resistance of plastic films, injection-molded parts, and sheets.

  3. Applicable to engineering plastics like ABS, SAN, PET, and PBT, enhancing their anti-yellowing and anti-cracking properties in outdoor environments.

  4. Used in solvent-based industrial coatings, providing UV protection for coatings on metal surfaces and plastic components, extending the service life of coatings.

  5. Suitable for food-contact plastic materials, such as food packaging films and containers, providing long-term UV protection under compliance premises.
