SC200 is a mildly alkaline granular compound, designed for heavy-duty immersion and electro-cleaning. SC200 soaks away oils, grease, dirt, mill markings, buffing compounds and even finger prints in your immersion tank. SC200 is safe on steel, stainless steel, nickel, copper alloys and plastics. The economical powder quickly goes into solution to provide a longlived solution for use at moderate temperatures. SC200 will put a protective film on metal surface to protect it from corrosion and is easily removed by rinsing.
