ABSTRACT:
Loading resistant coated abrasives can be made without the need for a supersize coating of metal stearates or any other material by incorporating phosphoric acids, partial esters of such acids, amine salts of such acids and partial esters, and/or quarternary ammonium salts with at least one long substituent group into amino resin or glue sizing adhesives used during the manufacture of the coated abrasives. Loading resistance equal or superior to that achieved with conventional zinc stearate supersized products can be achieved in this way.
