Title:
ABRASIVE GRAIN AGGLOMERATES, PROCESS FOR THE PRODUCTION THEREOF AND THE USE THEREOF FOR PRODUCING ABRASIVES
Document Type and Number:
WIPO Patent Application WO/2010/040472
Kind Code:
A3
Abstract:
The present invention relates to abrasive grain agglomerates composed of fine-particle primary abrasive grains which are held together by means of a binder based on an aluminosilicate having a molar ratio of Al2O3 to SiO2 of from 1:2 to 1:20. The particular advantage of these abrasive grain agglomerates is that the binder cures fully at below 450°C, preferably below 400°C, to form abrasive grain agglomerates having an extraordinarily high strength.
