Abstract

A homogenous non-tacky thermosetting plastic powder mixture formed by mixing component A comprising a solid phenol novolac resin powder and a hardener containing a small amount of an oil-like substance liquid at room temperature with component B comprising a liquid resol, fillers and optionally additives which when containing an abrasive are useful for the production of filler-containing shaped elements or resin-bonded grinding elements.
