Description

10,10-Oxybisphenoxarsine is an organoarsenic compound primarily valued for its potent antimicrobial and preservative properties. This chemical is critical for preventing the growth of bacteria, fungi, and algae in a wide range of industrial materials. It is essential for manufacturers in the polymer, paint, adhesive, and textile industries seeking long-term product protection against biodeterioration.

Application

• As a biocide and preservative in PVC, polyurethane, and other polymer systems.
• For the protection of adhesives, sealants, and caulks from microbial degradation.
• In the formulation of paints, coatings, and marine antifouling paints to inhibit mold and algae.
• As an antimicrobial agent in textile finishes and industrial fabrics.
• For the preservation of construction materials like wood composites and insulation.
• In paper and paperboard coatings to provide wet-state microbial resistance.
• As a component in cooling water treatment programs to control biofouling.
