Purgitol® TMB is used as a sump cleaner and/or additive to soluble oil (or synthetic coolant) systems in machine shops as an emulsifier of “tramp” oils and a system cleaner. Purgitol® TMB loosens sludge and metallic buildup in lines, settles heavy particles, and kills bacteria and fungus while it protects against stains and rust on ground or polished surfaces. Purgitol® TMB can be used on steel, cast and malleable iron, and on non-ferrous metals, however, a darkening of aluminum will occur upon prolonged contact.
