Blasocut BC20SW water soluble metalworking fluid contains mineral oil-based micro emulsions for extended tool life. It has been developed specifically for usage with soft water, and it achieves extended sump life through Blaser's biological concept that eliminates the need for tank-side additives or biocides. The fluid is designed for machining and grinding of ferrous and non-ferrous materials and difficult operations. It is recommended for use for foam control in soft water that contains less than 180-ppm calcium.
