Compounds are added to the disc finishing machines during the grinding process in order to produce clean, bright and non-corroded workpiece surfaces. With impact-sensitive workpieces, the compound creates a foam buffer betweem the workpieces and the abrasive media. The compounds supplied by OTEC not only provide the best possible finishing results, but are also easy to break down in the waste water treatement system because they do not contain strong complexing agents.

UC 12 Ultrasonic Cleaning Compound

The special composition of the new UC12 ultrasonic cleaning compound from OTEC makes it especially suitable for a wide range of applications.Due to its degreasing properties, oils, fats and waxes are easily removed from the surface. Oxidation, oxide scale and solder residues are efficiently removed to facilitate subsequent processes. Of course, UC 12 also cleans tarnished surfaces and has an additional brightening effect. Many metals and metal alloys can be cleaned, including gold, silver, copper, brass, tombac, bronze, aluminium and stainless steel. UC 12 is preferably used at a working temperature of 50°C - 80°C. Even at temperatures above 80°C the surface of parts will not tarnish.The product itself can easily be treated in a waste water processing unit or a micro filtration unit unless the process involves oils, fats and waxes.
