Water Dilutable Metalworking Fluids A summation of well defined definitions on the more common terms used in the analysis of water diluted metalworking fluids. Dermal Study on Rats and Mice with Diethanolamine Etna Products, Inc. has long been committed to understanding the potential health issues associated with the raw material and finished products that it produces and to communicating those concerns to our associates and customers. The selection of elastomers for the metalworking industry requires balancing the elastomeric properties to suit the particular application. The key elastomer compounds to consider are the polymer type, the cure system, and the filter content. The primary metalworking fluid components to consider are the oil, water, and alkalinity level.
Many problems associated with elastomers in metalworking fluids are the results of contamination.
Simulated service testing can be a useful tool to judge the relative chemical compatibility of elastomers with the various types of metalworking fluids . Top of Page Formicary Corrosion of Copper Tube Formicary corrosion is a problem that has been known for years, although relatively little work has been done to research this phenomena. Yamanchi, Motoyo, and others have conducted the bulk of the work in the 1980s. The end result of this tunneling effect can be pin hole leaks in copper tube. Identifying formicary corrosion can in many instances be quite difficult.
