In the abrasive sector, phenolic resins are mainly used for metal finishing e.g. for grinding wheels, cut-off wheels and as binders for sandpaper. Mainly our high-quality kaolins and calcium carbonates are used in this applications. In addition, the use of calcium carbonate improves the spacing between the individual grains. Kaolin, on the other hand, can also be used in urea-bonded abrasives.
