Description

2-Hydroxy-4-[2-Hydroxy-3-(Octoxy)Propoxy]Phenyl Phenyl Ketone is a specialized organic compound belonging to the class of benzophenone derivatives, functioning as a highly effective light stabilizer. Its core value lies in its ability to absorb and dissipate harmful ultraviolet (UV) radiation, thereby preventing photodegradation and extending the service life of sensitive materials. This product is essential for formulators and manufacturers in the polymer, coatings, and specialty chemical industries who require reliable UV protection for their end products.

Application

• Primary use as a UV absorber and light stabilizer in polymer systems including polyolefins (PP, PE), PVC, and engineering plastics.
• Protective additive in industrial and automotive coatings, paints, and varnishes to prevent color fading and surface cracking.
• Enhancement of lightfastness in adhesives, sealants, and elastomers exposed to outdoor conditions.
• Stabilizing component in packaging materials to protect contents from UV-induced damage.
• Used in the formulation of personal care products such as sunscreens, where it acts as a UV filter (subject to regional regulatory approval).
• Application in agricultural films to improve durability and performance under sunlight.
