Unchecked growth of microorganisms in metalworking fluids can cause fluid deterioration, resulting in damage to fluid handling systems, tools, and the work-piece. These problems can be controlled through the proper use of biocides. These problems may also be caused by other conditions. Therefore, we recommend making post treatment additions of Tiansland BNT Antimicrobial after testing the fluid for the presence of microorganisms.
Many of the antimicrobials commonly used in metalworking fluids are effective against bacteria, but provide only limited protection against fungi. In the absence of bacteria, the fungi – which no longer have to compete with the bacteria for food – proliferate and cause odors, clogged filters and fluid breakdowns. As a result, it is often necessary to use two or more products to obtain optimum protection.
Tiansland BNT Antimicrobial is a broad-spectrum antimicrobial designed to quickly combat both bacteria and fungi commonly found in contaminated metalworking fluid systems. It is a blend of two well-known metalworking preservatives, each with a long history of effective use. The first material is a highly effective fungicide; and the other a fast acting bactericide. The ratio of the two components has been carefully chosen to provide maximum post treatment protection to metalworking fluid systems. Tiansland BNT Antimicrobial use in metalworking, cutting, cooling, and lubricating fluids.
DIRECTIONS FOR TANKSIDE ADDITIONS
We offer the following advice when making post treatment additions of Tiansland BNT Antimicrobial.
1. Confirm the size of the system at the current operating level and determine the amount of Tiansland BNT Antimicrobial necessary to treat the system.
2. Carefully measure the biocide dose before adding it to the reservoir.
3. To ensure proper mixing, make post treatment additions of Tiansland BNT Antimicrobial into areas of the metalworking fluid reservoir where there is good circulation.
4. For this biocide to be most effective, the addition should be made after any other required chemical, metalworking fluid concentrate, or make-up water addition.
RECOMMENDED USE LEVELS
The amount of Tiansland BNT Antimicrobial used should never exceed the maximum dose of 2000 ppm (parts per million) product, as sold. Typical post treatment dose levels for this product are between 1000 and 1500 ppm product, as sold.
Gennerally: Concentrate: 2.0– 4.0%
Tankside: 0.1 – 0.2%
The need for a biocide addition should be based on the results of standard microbiological tests (i.e. commercially available dipsticks) or chemical analysis for the active ingredient. Tiansland can provide methods for determining the level of active ingredient in the dilute metalworking fluid. When bacterial levels reach 10 5 CFU (colony forming units) or fungi are detected (or other levels determined by your fluid supplier), an addition of Tiansland BNT Antimicrobial should be made. We recommended waiting 24 hours prior to conducting another microbial evaluation. If repeated doses are found to be necessary within a limited time frame contact should be made with the fluid or biocide supplier. This scenario is usually indicative of either an incompatibility of the biocide with the metalworking fluid or a more serious microbial problem.
THE IMPORTANCE OF RECORD KEEPING
Careful record keeping is essential for maintaining a clean system. The results of standard tests on a system (such as bacterial and fungal counts, pH and alkalinity) should be recorded regularly. A log of post treatment additions, biocide levels, and visual observations should also be kept. This type of record keeping can detect trends and serve to alert workers to a possible problem before the situation gets out of hand. In addition, data can be passed along to the fluid or biocide supplier when they are called upon to solve a problem.

Tiansland BNT Antimicrobial is compatible with the ingredients found in most metalworking fluids and is stable over the pH range (8.0-9.5) of most metalworking fluids and should not adversely affect the working pH of a metalworking fluid system.
