Description

2-Hydroxy-4-(2-Phenoxyethoxy)Benzophenone is a specialized organic compound belonging to the benzophenone class of chemicals. This product matters as a highly effective light stabilizer and UV absorber, protecting materials from photodegradation and extending their service life. Industries that need it include polymer manufacturing, coatings, adhesives, and specialty chemical production where long-term stability against ultraviolet radiation is critical.

Application

• Primary use as a light stabilizer and UV absorber in polymer systems, including polyolefins (PP, PE), PVC, and engineering plastics.
• Protective additive in industrial coatings, paints, and varnishes to prevent yellowing and loss of gloss.
• Enhancing the weatherability and colorfastness of adhesives, sealants, and elastomers.
• Stabilizer component in packaging materials to protect contents from UV light.
• Used in the formulation of sunscreen agents and personal care products (subject to specific regulatory approval and grade).
• Additive for specialty inks and dyes to improve fade resistance.
• Potential use in agricultural films to extend durability under sunlight.
