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.

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.

Subchronic Effects and Other Studies
Additional data is available on request from the Troy Chemical Corporation on active ingredient and other hazardous components.


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.
