Description

Potassium Sodium 2,2'-Methylenebis[3,4,6-Trichlorophenolate] is a specialized organochlorine compound primarily utilized as a high-performance preservative and biocide. This chemical matters for its potent antimicrobial efficacy, offering reliable protection against a broad spectrum of microorganisms in demanding industrial formulations. It is needed by manufacturers in the paints and coatings, adhesives, polymer, and wood preservation industries where long-term product stability and resistance to biological degradation are critical.

Application

• Paints and Coatings: Acts as a powerful in-can preservative and dry-film fungicide to prevent spoilage and surface mold growth.
• Adhesives and Sealants: Provides essential protection against microbial degradation, extending shelf life and maintaining performance.
• Polymer Emulsions and Dispersions: Used as a biocide to prevent bacterial and fungal contamination during storage and application.
• Wood Preservation: Serves as a key component in formulations designed to protect timber from rot, fungi, and insect damage.
• Construction Materials: Incorporated into caulks, grouts, and other building materials to inhibit mold and mildew formation.
• Industrial Fluids: Used in metalworking fluids and other process waters as a microbicide to control biofouling.
