Abstract
Corrugated abrasive discs such as grinding wheels are treated by applying a water-resistant coating to the interiors of the corrugations before the corrugations are plugged. Discs having water-sensitive matrices such as magnesium oxychloride cement are thus protected against water or water vapor seepage from aqueous-based plug fill material.
