Description

Zinc 3,5-Di-tert-Butylsalicylate (97%) is a high-purity organometallic compound primarily used as a versatile stabilizer and catalyst component. This product is valued for its ability to impart thermal and light stability to polymers and other materials, enhancing product longevity and performance. It is an essential raw material for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to improve the durability of their formulations.

Application

• Polymer Stabilizer: Acts as a highly effective heat and light stabilizer for polyolefins (e.g., PP, PE), PVC, and other polymers to prevent degradation during processing and end-use.
• Lubricant & Grease Additive: Functions as an antioxidant and anti-wear agent in synthetic lubricants and industrial greases, extending service life under high-temperature conditions.
• Catalyst & Co-catalyst: Serves as a component in Ziegler-Natta and other coordination catalyst systems for olefin polymerization.
• Crosslinking Agent: Used in the production of specialty elastomers and silicone polymers to achieve specific mechanical properties.
• UV Absorber Synergist: Works in conjunction with primary UV absorbers (e.g., hindered amine light stabilizers) in coatings and plastics for enhanced weatherability.
• Antioxidant for Fuels & Oils: Provides oxidative stability to hydrocarbon-based fuels, transformer oils, and industrial fluids.
