Kathon 886-MW Biocide

Soluble, synthetic, and semi-synthetic metalworking fluids or coolants provide an excellent environment for the growth of various microorganisms, including bacteria, mold, and yeast. If allowed to grow, these organisms can have detrimental effects on the fluids. For example, bacteria, which can grow very quickly, can destroy the integrity of the fluid by discoloration destroying lubricity characteristics, and causing emulsions to split. Bacteria can also reduce the pH of the fluid, which can promote corrosion. Some forms of bacteria have objectionable odors. Fungi typically grow more slowly than bacteria, but can form large masses which clog filters and lines and in some cases lead to system shutdown; fungi also generate foul odors and can cause corrosion.

KATHON biocides have been used safely and effectively in a variety of industries around the world for more than 20 years. In 1977 Rohm and Haas Company was granted EPA registration for KATHON 886 MW microbicide for use in metalworking fluids, in 2 piece can manufacture, hot aluminum rolling, and general machinery of ferrous and aluminum materials. In 1986, this registration was expanded to include the use of KATHON 886 MW microbicide in metal cleaners and water-based hydraulic fluids.

The information in this brochure has been compiled to familiarize users of KATHON 886 MW microbicide with its chemistry, to communicate the tremendous benefits of this product as well as the potential hazards, to provide directions for safe and efficient use of the product, and to aid the user in the event of misuse. Particular attention should be paid to the Compatibility section of this brochure which provides insight on the stability of KATHON 886 MW microbicide with individual components and additives frequently used in metalworking fluid operations.

KATHON 886 MW microbicide can be used safely and effectively by following the instructions and precautions outlined in this brochure, on the product label, and on the Rohm and Haas Material Safety Data Sheet.
