Col-K Polishing Suspension

Colloidal silica suspension is able to produce the ultimate in high quality mirror polishes on polishing machine. A part abrasive, part chemical polishing action makes colloidal silica well suited to polishing difficult materials such as Stellite and Cobalt Chrome.

One of the disadvantages of colloidal silica is that it can crystallise out of solution. The crystals have a corrosive action and can attack material.

Kemet has developed the next generation of colloidal silica – a non crystallising version called Kemet Col-K (NC). This is available in 1, 5 and 20 litre containers.
