KATHON™ 886 MW

• Highly effective microbicide. Extends metalworking fluid life, resulting in cost reductions due to less use of makeup fluid and lower waste disposals.
• Broad spectrum activity. Provides long lasting and effective contamination prevention versus bacteria and fungi.
• Efficacious versus specific problem-causing microorganisms. Effective against Mycobacterium and endotoxin-producing bacteria (based on controlled laboratory studies).
• Good temperature and pH stability. Works well in a variety of metalworking conditions up to 60°C (140°F) and up to pH 9.2.
• Easy to dose. Highly soluble in water and does not foam.
• Provides long-lasting microbial control. Cost effective versus competitive tankside treatments.
• Fast acting. Quickly controls microbial activity and odor-causing bacteria and fungi.
• Effective at low use rates (10 to 17 ppm active ingredient).
• Does not contain or release formaldehyde.

Metalworking Fluid Preservation:

• For maintenance of a non-fouled system, use KATHON™ 886 MW at 2.7 fluid ounces (0.23 pounds) per 1,000 gallons of emulsion every 4 weeks or 2.7-12.8 fluid ounces (0.23-1.1 pounds) per 1,000 gallon of emulsion every 4-12 weeks to provide 26-125 ppm product (4-17.5 ppm active isothiazolones). For a noticeable fouled system use an initial dose of 5.4-12.8 fluid ounces (0.46-1.1 pounds) per 1,000 gallons of emulsion followed by subsequent maintenance dosages depending upon the treatment interval noted above.

Metal Cleaning Fluid Preservation:

• KATHON™ 886 MW is recommended as a preservative for the manufacture and use of alkaline, acid, and emulsion-based metal cleaning fluids typically used in electroplating, phosphatizing, galvanizing, and general metal cleaning operations.
• For addition to a metal cleaning concentrate add KATHON™ 886 MW at a level to ensure that the final use-dilution fluid contains 44 to 147 ppm as supplied (6.25 - 25 ppm active isothiazolones).
• When direct addition to a fouled system, add 5.6-22.6 fl. oz (0.48-1.9 lbs) of microbicide to each 1,000 gallons of use-diluted metal cleaning fluid every 3 to 4 weeks to provide 44 to 177 ppm as supplied (6.25 to 25 ppm active isothiazolones).

Water Based Hydraulic Fluid Preservation:

• KATHON™ 886 MW is recommended as a preservative for use in the manufacture and use of high water-based hydraulic fluids and invert emulsion hydraulic fluids.
• For the maintenance of a nonfouled system, use KATHON™ 886 MW at 9-13 fluid ounces (0.76-1.1 lbs) per 1,000 gallons of fluid every 8 weeks. For a noticeably fouled system use an initial dose of 13 to 20 fluid ounces (1.1-1.7 lbs) per 1,000 gallons fluid followed by subsequent maintenance doses.
• Add KATHON™ 886 MW to the fluid at a temperature below 60°C (140°F) to reduce degradation of the active ingredient.
• For all three applications, increased frequency of treatment may be required depending upon rate of dilution of the preservative with makeup fluid, the nature and severity of contamination, level of control required, filtration effectiveness, and system design, etc. Based on laboratory studies, repeated doses of KATHON™ 886 MW are not expected to cause corrosion.

Compatibility:

• KATHON™ 886 MW is compatible with most additives used in metalworking fluids.
• The level of compatibility may vary.

Solubility:

• KATHON™ 886 MW is soluble in water, methanol, ethanol, isopropyl alcohol, acetic acid, and 3.5 parts n-butanol. KATHON™ 886 MW is insoluble in acetone.

Stability:

• KATHON™ 886 MW is stable over a wide pH range (3.0 - 9.2) in water and metalworking fluid systems.
• Its stability and performance are improved at lower pH. Whenever possible the pH of a system should be maintained below pH 9.2.

• In general, avoid eye and skin contact, wear safety goggles, gloves and protective clothing.
• In case of eye or skin contact despite precautionary measures, wash immediately and thoroughly with plenty of warm water and obtain medical attention. 
• The legal requirements prevailing in your country, especially on working hygiene and in the avoidance of accidents, must be observed.
