Abstract
A cloth backing for an abrasive article is treated by combining a phenolic resin, a latex and a colloidal silicon oxide composition to prepare a colloidal formulation, which is then applied to the cloth backing and cured. Coated abrasive articles are formed by applying a make coat formulation to the treated cloth backing, applying an abrasive and then curing the make coat formulation.
