Abstract
Abrasive products and methods of producing such products are described. The resin systems utilized are particularly suited to use in the manufacture of coated adhesive products. The coated abrasive products have a plurality of resin layers. The products have at least one layer comprised of an electron curable resin and at least one layer comprised of a heat curable resin. The products may include both electron and heat curable resins combined in a single layer.
Claims19
A coated abrasive wherein at least one layer is comprised of a mixture of an electron radiation curable resin system comprising an oligomer, filler and a diluent wherein the electron-curable resin is selected from urethane-acrylates or epoxy acrylates and a heat curable resin system wherein the heat curable resin is selected from phenolic resins, melamine resins, amino resins, alkyd resins and furan resins.
The method of forming a coated abrasive product comprising the steps of:
- (a) coating a fibrous substrate with a plurality of successive layers of resin, at least one layer comprised of an electron beam curable resin, and at least one layer comprised of a heat curable resin;
- and
- (b) applying at least one intermediate layer of particulate abrasive material.
