Abstract
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.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
63 words
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.
Claim 2
Dependent Claim
63 words
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.
Claim 3
Dependent Claim
17 words
The coated abrasive of claim 1 wherein the heat curable resin system is comprised of phenolic resin.
Claim 4
Dependent Claim
14 words
The coated abrasive of claim 2 wherein the phenolic resin is a resole resin.
Claim 5
Dependent Claim
19 words
The coated abrasive of claim 1 wherein the mixture contains up to about 50% by weight heat curable resin.
Claim 6
Dependent Claim
20 words
The coated abrasive of claim 1 wherein the mixture contains from about 25 to about 45% by weight phenolic resin.
Claim 7
Dependent Claim
13 words
The coated abrasive of claim 1 wherein the mixture further contains a surfactant.
Claim 8
Dependent Claim
13 words
The coated abrasive of claim 1 wherein said mixture further contains a colorant.
Claim 9
Dependent Claim
14 words
The coated abrasive of claim 1 wherein said diluent is an acrylic acid derivative.
Claim 10
Dependent Claim
13 words
The coated abrasive of claim 1 wherein said diluent is a pyrrolidone derivative.
Claim 11
Dependent Claim
19 words
The coated abrasive of claim 1 wherein the backing of said coated abrasive comprises cotton cloth or waterproof paper.

Claim 14
Independent Claim
59 words
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.
Claim 15
Independent Claim
59 words
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.
