Polishing compound Vetropol

Vetropol is a special aluminium oxide-based polishing agent for the chemical-mechanical polishing and cleaning of flat glass (also before sputtering).
It is used to remove strongly adhering impurities, swirls and haze, small and minute scratches as well as an initial state of glass corrosion. Unlike cerium oxide-based polishes, Vetropol is very easy to wash off and has a chemically defined composition. It reduces the roughness of the glass surface as well as the sodium content, which leads to the minimisation of coating defects. To optimise the removal and polishing performance, an aluminium oxide with a grain size that is as uniform as possible, i.e. a narrow grain distribution, was selected. 84% of the polishing particles are between 1 μm and 10 μm. The proportion of particles below 1 μm, which therefore have no influence on removal, was minimised. Particles larger than 25 μm, which could cause recognisable scratches, are not included. Vetropol is used on flat glass polishing machines equipped with disc brushes or polishing pads, among other things. The concentration of the solution used depends on the degree of soiling and the equipment used and is between 30 - 80 g/litre. The product must be stirred or shaken well before use. It is then diluted with the appropriate amount of water in the polishing agent container. To prevent sedimentation, it is recommended not to stop the stirrer. Even after long breaks, the polishing agent can be slightly suspended when the agitator is switched on again.
