Left untreated, metalworking fluids can become contaminated with microorganisms. Build-up of bacteria and fungi can cause foul odors, and lead to slime and biofilm that clogs filters and can cause corrosion. Microbial contamination can also lead to split emulsions, pH drift, and other reductions in fluid performance parameters such as lubricity or cooling.

An effective biocide treatment plan is essential to help prevent contamination of your metalworking fluids. We offer a broad range of highly effective products suitable for either tankside or concentrate application which will protect your products from microbial attack, biofilms formation mycobacteria growth and other issues.
