Estimating the term…
A coated abrasive product comprising abrasive granules adherently bonded to at least one major surface of a backing sheet by a radiation curable resinous binder material. The binder material can be used to form the make coat, size coat, or both coats. Alternatively, the binder material can be used in embodiments where only a single binder coat is employed. The radiation curable resinous binder material comprises a copolymer formed from a mixture comprising (1) at least one monomer selected from the group consisting of isocyanurate derivatives having at least one terminal or pendant acrylate group and isocyanate derivatives having at least one terminal or pendant acrylate group, and (2) at least one aliphatic or cycloaliphatic monomer having at least one terminal or pendant acrylate group.
A coated abrasive product comprising abrasive granules which are supported on and adherently bonded to at least one major surface of a backing sheet by a make coat of a first resinous binder material and a size coat of a second resinous binder material, at least one of said first resinous binder material or said second resinous binder material comprising a copolymer formed from a mixture comprising (1) at least one monomer selected from the group consisting of isocyanurate derivatives having at least one terminal or pendant acrylate group and isocyanate derivatives having at least one terminal or pendant acrylate group, and (2) at least one aliphatic or cycloaliphatic monomer having at least one terminal or pendant acrylate group.
The method of claim 20 wherein said ionizing radiation is electron beam radiation.
A coated abrasive product comprising abrasive granules which are supported on and adherently bonded to at least one major surface of a backing sheet by a resinous binder material, said resinous binder material comprising a copolymer formed from a mixture comprising (1) at least one monomer selected from the group consisting of isocyanurate derivatives having at least one terminal or pendant acrylate group and isocyanate derivatives having at least one terminal or pendant acrylate group, and (2) at least one aliphatic or cycloaliphatic monomer having at least one terminal or pendant acrylate group.
