Description

2-Hydroxy-4-[(3-Methylheptyl)Oxy]Phenyl Phenyl Ketone is a specialized organic compound belonging to the class of benzophenone derivatives. This chemical is valued for its role as a highly effective ultraviolet (UV) light absorber and stabilizer in polymer formulations. It is primarily required by manufacturers in the plastics, coatings, and specialty chemical industries seeking to enhance the durability and longevity of their products against photodegradation.

Application

• As a primary UV light stabilizer in polyolefins such as polyethylene (PE) and polypropylene (PP).
• To provide photostability in automotive coatings, industrial paints, and wood varnishes.
• As an additive in adhesives and sealants to prevent yellowing and embrittlement from sunlight exposure.
• For the stabilization of plastic films and packaging materials against UV-induced degradation.
• In the formulation of masterbatches and polymer concentrates for easy dispersion in final products.
• As a protective agent in synthetic fibers and textiles to improve colorfastness and material integrity.
