Description

Zinc Cinnamate is an organometallic salt derived from cinnamic acid, serving as a versatile functional additive. Its primary value lies in its role as a highly effective and stable ultraviolet (UV) light absorber and corrosion inhibitor. This compound is essential for formulators in the polymer, coatings, and personal care industries seeking to enhance product durability and longevity. Zinc Cinnamate CAS NO 18957-59-0 offers a synergistic combination of UV stabilization and metal passivation properties.

Application

• Polymer Stabilizer: Used as a UV absorber and light stabilizer in plastics (e.g., PVC, polyolefins) and synthetic rubbers to prevent photodegradation and yellowing.
• Coatings & Paints: Incorporated into industrial and automotive coatings to improve weatherability, gloss retention, and protect against UV-induced film breakdown.
• Corrosion Inhibition: Functions as a corrosion inhibitor in metal pretreatment formulations, protective primers, and anti-corrosive pigments.
• Personal Care Products: Acts as a broad-spectrum UV filter and stabilizer in sunscreen formulations and cosmetic products requiring photostability.
• Adhesives & Sealants: Enhances the long-term performance and resistance to environmental aging of high-performance adhesives and sealants.
• Wood Preservatives: Used in coatings and treatments for wood to protect against UV damage and fungal growth.
