Micro-Tec diamond polishing pastes

Micro-Tec diamond polishing pastes are designed for polishing and cleaning of metals, alloys, glass, ceramics, semiconductors and other hard materials. They are also suitable for polishing metallographic and petrographic samples and use an oil-based formula which can be applied using polishing cloths. The Micro-Tec diamond polishing compound is made from mono-crystalline synthetic, diamonds mixed with a mineral and vegetable oil-based compound. The diamond powder is micron graded and mixed into the colour-coded paste to distinguish between sizes. Oil soluble carrier compounds bind the paste together very well, even when high speed polishing discs are used. Use lubricants or extenders which are compatible with oil based (oil soluble) diamond paste. Available in 12 sizes from 0.5µm to 40µm and a set containing one of each size - supplied in five syringes for easy application.

Using diamond polishing pastes

Most grinding, lapping and polishing using diamond paste is done progressively - starting with a coarser grade and finishing with a finer grade. Make sure the sample or work piece is thoroughly cleaned/rinsed before using a finer grade diamond paste. Apply the diamond paste on a billiard table-type cloth and spread evenly - a lubricant or extender (mixture of glycol / alcohol / water / detergent) can be used to thin the paste.
The grade to start with depends on the conditions of the surface. If a micro-finish grinding or lapping paper is used prior to the polishing step, then one could start with the 10µm or 6µm grade and step down to 3µm and 0.5µm. For coarser surfaces consider starting with 20-40µm grade and then gradually step down to 0.5µm.
Warning: diamond powder is a hard material and can easily be pressed into the surface of soft materials (e.g. aluminium, copper, tin etc.) so use of light pressure is recommended.
