Pumice is a natural polishing media ideal for metal treatments. Due to its unique physical structure, our pumice has a smooth but effective abrasive action suitable for copper treatments. The microscopic action of the pumice particles creates a surface ideal for maximum adhesion of coatings in aluminium extrusions. Pumice leaves metal surfaces smooth with a satin-like finish.
Techfil Recommends its pumice for surface finishing prior to etching and engraving.
In the jewellery and silver trade, pumice is recommended as a buffing media.
Pumice is used in the first stage of polishing, where fine abrasive media is required. Without buffing, the final mirror finish cannot be achieved by polishing technicians.
