Description

Potassium 3,5-Bis(tert-Butyl)-4-Hydroxybenzoate is a high-performance antioxidant salt derived from a hindered phenolic acid. This compound is valued for its excellent stability and effectiveness in protecting materials from oxidative degradation. It is primarily utilized in the polymer, lubricant, and specialty chemical industries where long-term thermal and oxidative stability is critical for product performance and longevity.

Application

• Primary antioxidant and stabilizer in polyolefins (e.g., polyethylene, polypropylene) and engineering plastics.
• Additive in synthetic lubricants, greases, and industrial oils to prevent oxidation and extend service life.
• Stabilizing component in adhesives, sealants, and elastomers to enhance durability.
• Intermediate in the synthesis of more complex polymer additives and specialty chemicals.
• Stabilizer for hydrocarbon-based fluids and fuels.
• Potential use in coatings and paints requiring UV and thermal resistance.

Quality Control

Our production of Potassium 3,5-Bis(tert-Butyl)-4-Hydroxybenzoate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency meet the high standards required for industrial applications. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; containers must be kept tightly sealed after opening to minimize exposure to air and moisture. For long-term storage, consider using an inert atmosphere.
