Description

4-(2-Ethylhexyloxy)-2-Hydroxybenzophenone is a specialized organic compound belonging to the benzophenone class, functioning as a highly effective ultraviolet (UV) light absorber. This compound matters for its critical role in protecting materials from photodegradation, thereby extending their service life and maintaining their physical and aesthetic properties. Industries requiring durable, light-stable products, such as plastics, coatings, and adhesives, need this additive to ensure long-term performance and color stability under UV exposure.

Application

• Primary UV stabilizer in polyolefins (PP, PE), PVC, and engineering plastics to prevent yellowing and embrittlement.
• Key additive in protective coatings, paints, and varnishes for automotive, industrial, and architectural applications.
• Enhances the lightfastness of adhesives, sealants, and synthetic fibers.
• Used in the formulation of personal care products like sunscreens and cosmetics for UV filtering (subject to regional regulatory approval).
• Stabilizer for packaging materials to protect contents from light-induced degradation.
• Additive in rubber and elastomer products to improve weathering resistance.
