(odour) or in 4 weeks. No maintenance was required, and the packet was safe to handle and dispose. In expanding the fluid maintenance market to include small machine applications, it was estimated that the potential existed for $20 million in added sales volume. In 2004, there were an estimated 150,000 potential customers for SuperBio. Biochemical users worked with either nonferrous metals such as aluminum, copper, tungsten, and titanium or ferrous metals such as iron and steel. Nonferrous metals- Nonferrous operations required the metalworking fluid to be kept completely free of bacteria because of the sensitivity of the metal to staining, and microbiologists and chemists were often employed to develop biochemical treatments and monitor systems closely. Central systems were prevalent in these industries and used metalworking fluid in reservoirs as large as 150,000 gallons. With 70%-80% share of this $3 to $% million market, Biochem + was the favored biochemical of many of these companies
