Preservation for metalworking fluids

Microbiological spoilage of water-mixed metalworking fluids is one of the biggest threats to quality, work and process safety of metalworking processes and for the health of employees.


Our task

When choosing a suitable preservative for a metalworking fluid there are various factors to consider – different ingredients, pH value, compatibility, legal approvals and climate conditions – to name a few. The large number of possible microorganisms cannot be covered by just one microbial active.


Our solution

schülke offers the metalworking industry a complete range of tailor-made biocides for all possible applications; such as preservation of metalworking fluid concentrates, post treatment of water mixed metalworking fluids and microbiocidal system cleaners.
