FLEXIBLE ABRASIVE ARTICLE RELEASING LOW AMOUNTS OF CONTAMINANTS

摘要

The present invention provides a flexible abrasive article comprising abrasi ve particles adhered to a foraminous substrate with at least one binder wherein the abrasive article comprises less than 300 ppb of selected extractable cation particles and less than 500 x 106 releaseable particles per square meter. The following method of making of such abrasive article is provided: coating the foraminous substrate (100) with a make coating to form a coated substrate; (20) coating the coated substrate (100) with abrasive particles t o form a particle coated substrate; (22) curing the particle coated substrate; coating the cured particle coated substrate with a size coating to form a sized-coated substrate; (28) curing the sized-coated substrate; converting t he cured, sized-coated substrate to form a shaped abrasive article; post-cleani ng the shaped abrasive article to remove undesired contaminants; and packaging the cleaned shaped abrasive article.
