Product Description
Preventol CMK (p-Chloro-m-cresol, PCMC, CAS No. 59-50-7) is a premium antimicrobial and preservative designed for industrial applications requiring long-term microbial control. This phenolic biocide effectively inhibits bacteria, fungi, and yeast, ensuring extended product shelf life and maintaining performance even under harsh conditions such as high pH, elevated temperatures, and complex chemical systems.
As a crystalline solid with off-white to pale yellow appearance, Preventol CMK offers excellent chemical stability and broad compatibility. It is slightly soluble in water and soluble in alcohols, oils, and organic solvents, enabling uniform distribution in coatings, adhesives, emulsions, and metalworking fluids. Its robust antimicrobial activity protects products against microbial contamination during storage, transport, and use.
Applications
Industrial coatings, paints, and varnishes requiring mold and bacterial resistance
Adhesives, sealants, and polymer dispersions
Metalworking fluids and cutting oils for microbial control
Electronic materials and specialty chemicals requiring contamination prevention
Water-based and solvent-based industrial systems where long-term stability is critical
Packaging
Preventol CMK is available in 25 kg fiber drums or 25 kg cartons with PE inner lining to prevent moisture absorption. Customized packaging can be provided according to client specifications.
