Abstract

Abstract The invention provides resin compositions which are particularly suitable for utilization in electron cured coated abrasives. The resin systems of the instant invention have been devised to be particularly suitable for the backing fill of a cloth which is to form the base of a coated abrasive. The formation of a treated base cloth for coated abrasive formation by electron beam curing resins creates a product which in addition to being suitable for immediate formation into a coated abrasive by application of grain is further a product which may be stored for later use or sold to other parties that have need for a waterproof stretch-resistant cloth or that make coated abrasives without doing cloth finishing. The invention also encompasses the formation of electron curing resin systems which are particularly desirable for the make coat and size coat utilized in forming coated abrasives. It is within the system of the invention to utilize the electron radiation curing resins in combination with the conventional heat curing resins.
