Diamond pastes

Diamond pastes are used for the finishing and polishing of ferrous and nonferrous metals, steels and semiconductors, alloyed steels, cast irons, ceramics, metal ceramics, carbide, sapphire, glass, semiconductors, and drawing dies.

Paste made of synthetic diamond ACH micropowders, grit size M40, with normal diamond volume content and washable by water would be marked as follows: ACH M40 N W L.

Diamond pastes act on the workpiece surface chemically and mechanically. They form  fine-dispersion emulsions that allow for a smoother distribution of diamonds over the workpiece surface. The paste also contains active surface agents, which make washing easier and help to remove slightly  flammable liquids, chips and slag generated by the lapping process.

Pastes are produced with normal (N), higher (H) and extra-high concentration (E), depending on the volume content of diamonds and their grit size.
