Abstract
1340598 Abrasive tools NORTON CO 4 May 1971 [4 May 1970] 12993/71 Heading B3D [Also in Divisions C3 and B4-B5] Coated abrasive material comprises a backing member having abrasive grain adhered thereto by a maker adhesive, the ends thereof being joined together in overlapped position and having disposed therebetween an adhesive composition formed by curing an adhesive film which comprises the reaction product of a hydroxyl terminated polyurethane-polyester with a component having available isocyacate groups, the reaction product containing available isocyanate groups and being only partially cured (see Division C3). The coated abrasive sheet material is of conventional manufacture and may comprise a backing member of paper, cloth or vulcanized fibres sized with various materials, a bonding layer of, e.g. a resinous material such as a phenol-aldehyde or epoxy resin or a glue maker adhesive composition, optionally a sand size coat over the bonding layer and abrasive grains adhered thereto, the abrasive grains including those of flint, emery, garnet, silicon, carbide, aluminium oxide and zirconia-alumina grains.
