‘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.

In this technical bulletin, Master Chemical highlights the visible part of the Hazardous Materials Index System or HMIS. This system is used by the industry to quickly communicate health and safety information in a uniform visual manner to the end user of the product. This voluntary system was created to provide a quick reference to critical health and safety information.
The Hazard Communication Standard requires that companies using hazardous materials maintain a file of the current material safety data sheets (MSDSs) for all the materials listed in their hazardous material inventories. It is the user’s responsibility to request that the organisation supplying the product delivers the current MSDS to them. Master Chemical maintains pdf copies of the most current MSDSs on its website for customers.
The Hazard Communications Standard is a federal regulation that sets forth what minimum levels of information to provide to employees and how that information is to be delivered. This bulletin from Master Chemical presents the responsibilities of the standard.
Master Chemical looks at the issues associated with glass and plastic when used as glazing materials in windows on modern machine tools.
At its most basic, a coalescer is a very large (relative to the flow rate) tank where the free and mechanically dispersed oil contained in the fluid is allowed to raise to the surface and be removed. In this bulletin, Master Chemical offers thoughts about using coalescers in the metalworking fluids market that are based on extensive field experience with a variety of different units.
