Description

Fatty Acids, C8-18 And C18-Unsatd., Zinc Salts is a versatile metallic soap compound, primarily valued for its role as a hydrophobic stabilizer and lubricant in polymer systems. This product offers a synergistic combination of zinc's reactivity and the hydrophobic, film-forming properties of medium to long-chain fatty acids. It is essential for manufacturers in the plastics, rubber, and coatings industries seeking to improve product performance and processing characteristics.

Application

• Polymer Stabilizer: Acts as a cost-effective acid scavenger and lubricant in polyvinyl chloride (PVC) and other halogenated polymer processing.
• Rubber Industry: Used as an activator in the vulcanization process and as a release agent in rubber compound manufacturing.
• Coatings & Paints: Functions as a flatting agent, dispersant, and water repellent additive in various coating formulations.
• Grease & Lubricant Thickener: Serves as a component in the production of complex soap-based greases, providing structure and thermal stability.
• Personal Care & Cosmetics: Employed as an opacifying agent and texture modifier in creams, lotions, and makeup products.
• Wood Preservative: Used in formulations to impart water resistance and fungistatic properties to treated wood.

Quality Control

Our production of Fatty Acids, C8-18 And C18-Unsatd., Zinc Salts adheres to stringent quality management protocols. Each batch is analyzed to ensure consistent composition, purity, and performance characteristics. Certificates of Analysis (COA) detailing zinc content, moisture, acid value, and particle size distribution are available upon request to support your quality assurance and regulatory compliance needs.

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); the container must be kept tightly sealed to prevent caking and degradation due to atmospheric moisture.
