‘Formaldehyde donor biocides — what’s the future?’
With the impending reclassification of formaldehyde as a category 1B, presumed human carcinogen, the writing is on the wall for formaldehyde donor biocides. These compounds do not contain formaldehyde per se, but as their name suggests they release it, in very small amounts, in the process of killing bacteria. Formaldehyde donors are proven, stable and effective and for many years have been the preservatives of choice for the majority of metalworking fluid manufacturers. However, the new regulation may change that. According to Master Chemical, this reclassification emphasises why the research and development (R&D) of alternative metalworking fluids is so vital. Formulators who are completely reliant on old chemistry are certain to lose market share as those with a high commitment to R&D introduce next-generation products that are future proof.

This technical bulletin from Master Chemical explains how pH and alkalinity work hand-in-hand to dictate some metalworking fluid characteristics.
Because of the nature of metalworking fluids and the environment in which they are used, a certain amount of microbiological growth is inevitable. So the question is not ‘how do I run a system where there is no microbiological growth?’ (or growth below some arbitrary level) but rather ‘how do I control the microbiological growth below a level where it causes a problem?’ This technical article from Master Chemical addresses this question.
As this bulletin from Master Chemical explains, for a metalworking fluid to perform one of its key functions — to provide in-process corrosion prevention — it is critical that the fluid leaves a corrosion-resistant (residue) coating. Therefore, the question is not ‘does the fluid leave a residue?’ but rather ‘is the residue objectionable?’
After more than 50 years in the industry, Master Chemical has found that the cause of a corrosion problem can frequently be traced to a relatively short list of reasons
Electroshield, a Russian manufacturer, has improved cost efficiency by switching to Trim SC412, a semi-synthetic cutting and grinding fluid developed by Master Chemical.
