During the polymerization process, Coated abrasives products the binder precursor is polymerized or cured and converted into a solidified binder. The binder may be curable, Coated abrasives products and the resin may be provided as a monomer, oligomer, polymer, Coated abrasives products or a combination thereof. The binder precursor may be a condensation curable resin, an addition polymerizable resin, a radical curable resin, Coated abrasives products and/or a combination and blend of such resins. One type of binder precursor is a resin or resin mixture polymerized via a free radical mechanism. The polymerization process is initiated by exposing the binder precursor and a suitable catalyst to an energy source, Coated abrasives products such as thermal energy or radiant energy. Examples of radiant energy include electron beam, Coated abrasives products ultraviolet light, or visible light.
Examples of suitable binder precursors have aminoplast derivatives with α, β-unsaturated carbonyl side groups, isocyanurate derivatives with at least one acrylate side group, Coated abrasives products and those with at least one acrylate side group Isocyanate derivatives), vinyl ethers, epoxy resins, Coated abrasives products and mixtures and combinations thereof.
