There are 3 types of water-based metalworking fluid concentrates. Each type is defined by the amount of mineral oil it contains. Soluble oil fluids contain the most mineral oil, while semi-synthetic or "micro-emulsion" fluids contain lower amounts of oil. Synthetic fluids contain no mineral oil. The synthetic fluids discussed in this report form a transparent solution containing water-soluble lubricants, in place of mineral oil. (Synthetics that use emulsifed water-insoluble lubricants are an exception that is not discussed here.) Each type of fluid also contains a variety of other chemicals that provide additional performance properties. Product Announcements
