Description

10-(p-Chlorophenoxy)-10H-Phenoxarsine is a specialized organoarsenic compound primarily utilized as a high-performance biocide and preservative. Its value lies in its potent antimicrobial and antifungal properties, which are effective at low concentrations against a broad spectrum of microorganisms. This makes it a critical additive for manufacturers in the polymer, paint, adhesive, and sealant industries seeking long-term protection against microbial degradation.

Application

• Polymer and Plastic Stabilization: Incorporated into PVC, polyurethanes, and other polymers to prevent fungal and bacterial growth that can cause discoloration, odor, and structural weakening.
• Industrial Preservative for Coatings: Used in paint, varnish, and industrial coating formulations to protect the wet state in the can and provide in-film protection against mold and mildew.
• Adhesive and Sealant Protection: Added to water-based and solvent-based adhesives, caulks, and sealants to extend shelf life and maintain performance in humid environments.
• Textile and Fiber Treatment: Applied as a biocide in technical textiles, fabrics, and fibers to impart antimicrobial properties for specialized applications.
• Wood Preservation: Acts as a fungicidal component in treatments for lumber and composite wood materials to prevent rot and decay.
• Cooling Water Treatment: Utilized as a slimicide in industrial cooling water systems to control microbial fouling.
