GENERAL INFORMATION
APPLICATION RATE: Mergal BIT20 is an effective preservative for most aqueous applications.
Mergal BIT20 is used in aqueous or water-containing products and systems to control growth of bacteria and fungi.
Use rates are in percentage by weight and refer to the product Mergal BIT20.
In order to determine the most cost effective use level for Mergal BIT20 in a given use, field trials are suggested.
GENERAL RECOMMENDATIONS: For protection against bacterial attack, a concentration within the range of 0.02 – 0.35% of this product is almost invariably sufficient.

The use rate is 0.05 – 0.25% wt/wt in the following products: Adhesives, Building and Construction Compositions, Emulsion Paint and Coatings, Inks, Lattices, Leather Processing Solutions, Metalworking Fluids, Mineral Slurries and Dispersions, Paper Coatings, Pesticide Formulations, Polymer Emulsions, Textile Spin-Finish and Coatings.
Mergal BIT20 is approved for adhesives used in food packaging and food contact paper and paperboard coatings.
Use of Mergal BIT 20 must not exceed 0.21 mg/in2 (0.0326 mg/cm2) of finished paper and paperboard intended for contact with dry foods and 0.11 mg/in2 (0.0168 mg/cm2) of finished paper and paperboard intended for contact with aqueous and fatty foods.
Oil Recovery Systems: Drilling fluids, packer fluids, completion fluids: Polysaccharide fluid loss control agents and thickeners such as starch, guar, and xanthan gum at a use rate of 0.05 – 0.15% on fluid weight or 1.5 – 4.5% on the dry polysaccharide eight.
Subsurface injection waters such as polymer and micellar/polymer waterfloods: Thickeners such as polysaccharides and xanthan gum at a use rate of 0.05 – 0.15% on the solution weight. .

Description
Application/ Use
Highlights
Physical Properties
Antimicrobial Activity
Water dilutable soluble oil, semi-synthetic and synthetic metalworking fluid systems are highly susceptible to the growth of microorganisms.
Microbial contamination can result in slime generation, gas formation, malodors and the reduction or drift of pH in the fluid concentrate and the working dilution.
This contamination can diminish fluid performance and system efficiency, which can increase costs, decrease tool life, reduce productivity and cause machine shut-down.
The use of Mergal BIT20, a proven high quality preservative to control biodeterioration, will help maintain product functionality and increase the life of the metalworking fluid.
For use in concentrates during manufacturing and in post addition applications.
• Cost effective
• Excellent pH stability
• Formaldehyde free
• Broad spectrum of activity
• Outstanding stability in the presence of amines or high heat
• Ease of incorporation
• Excellent freeze-thaw stability, low freezing point
• Long-term efficacy

Environmental Effects
Mergal BIT20 is a liquid, organic broad spectrum preservative designed for use in both the concentrate and working dilutions of soluble oil, semi-synthetic and synthetic metalworking fluid systems which may be subject to microbial degradation.
Mergal BIT20, at appropriate use levels in both laboratory and field evaluations, inhibits the growth of microorganisms.
Products protected with Mergal BIT20 can generally resist the long-term, repeated challenge of microorganisms.
When used in metalworking fluid concentrates and working dilutions at application use levels of up to 0.15% (max.), based on the weight of the working dilution, Mergal BIT20 will protect against a broad range of gram positive and gram negative bacteria and other microorganisms.
The level of Mergal BIT20 required for optimum effectiveness is dependant on the composition and end use application of your specific product formulation.
Mergal BIT20 may be used in systems with commonly used fungicides such as Troyshield LA33, Troyshield FX20 and Troyshield FX40.
Customers are encouraged to check for compatibility and stability in their formulated systems.

Ecotoxicity
This product is moderately toxic to fish. Do not apply directly to water or wetlands. Do not contaminate water when disposing of equipment washwaters.
Data on the active ingredient, 1,2,-Benzisothiazolin-3-one (BIT), is as follows: LC50 (rainbow trout, 96 hr flow-through): 1.3-1.6 mg/kg.
LC50 (water flea, 48 hr flow-through): 1.5-3.3 mg/kg.
Environmental Fate
1,2,-Benzisothiazolin-3-one (BIT) is hydrolytically stable (half-life >30 days), but breaks down fairly quickly in aerobic soils (half-life <24 hours in sandy loam soil).
Its low Kow (20 at 25°C) indicates that it is unlikely to bioaccumulate in aquatic organisms.
