Description

Octadecyltrimethylammonium Pentachlorophenate is a quaternary ammonium salt of pentachlorophenol, functioning as a potent antimicrobial and preservative agent. This compound is valued for its dual-action efficacy, combining the surfactant properties of the ammonium cation with the biocidal activity of the pentachlorophenate anion. It is primarily utilized in industrial sectors requiring robust material protection, such as wood treatment, textile processing, and as a component in specialized biocidal formulations. Our supply ensures high purity and consistent quality to meet stringent industrial application standards.

Application

• Wood Preservative: Acts as a powerful fungicide and insecticide for pressure-treated lumber, utility poles, and railway sleepers.
• Industrial Biocide: Used in cooling water systems, pulp and paper mills, and oilfield operations to control microbial growth and biofilm formation.
• Textile Protectant: Imparts mildew and rot resistance to fabrics, canvas, and technical textiles.
• Antifouling Agent: A key component in marine paints and coatings to prevent the growth of barnacles, algae, and other organisms on ship hulls.
• Leather Processing: Employed as a preservative during the tanning and storage of hides to prevent bacterial degradation.
• Adhesive & Polymer Additive: Serves as a preservative in glue, latex, and polymer emulsions to extend shelf life.
• Research & Development: Used as a reference standard or active ingredient in the development of new antimicrobial formulations.
