Description

Silver, Octadecanoate is the silver salt of stearic acid, a compound of significant industrial interest. This material is valued for its unique combination of silver's biocidal properties and the hydrophobic, lubricating characteristics of the stearate anion. It serves as a critical functional additive and active ingredient for manufacturers in the polymer, coating, and specialty chemical sectors seeking antimicrobial efficacy and processing aids.

Application

• Antimicrobial Masterbatches & Polymers: Incorporated into polyolefins, PVC, and other polymers to impart long-lasting antibacterial and antifungal properties for medical devices, food packaging, and consumer goods.
• Specialty Coatings & Paints: Used as a functional additive to provide surface antimicrobial protection in architectural paints, marine coatings, and industrial finishes.
• Catalyst & Reagent: Serves as a precursor or catalyst in specific organic synthesis and polymerization reactions within fine chemical manufacturing.
• Lubricant & Stabilizer: Acts as a metal soap lubricant and heat stabilizer in the processing of rigid PVC and other halogenated polymers.
• Conductive Inks & Pastes: Utilized as a silver source in the formulation of specialty conductive inks for printed electronics.
• Textile Finishing: Applied to confer durable antimicrobial functionality to synthetic and natural fibers for medical textiles and activewear.

Quality Control

Our Silver, Octadecanoate is manufactured under a stringent quality management system. Each batch is analyzed to ensure consistent purity, particle size distribution, and functional performance. Comprehensive testing includes assay (silver content), identification, and control of key impurities. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee compliance with your specifications.

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 product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed after opening to minimize exposure to atmospheric moisture and light.
