Abstract: Abrasive material is provided in which a relatively thick, flexible, porous, abrasive layer is secured adhesively to a flexible backing member. In the manufacture of the abrasive material, abrasive grain is first coated with a liquid resinous binder composition after which the coated grain is then mixed with a solid, particulate, resinous binder composition, the latter binder being more resistant, after curing, to distortion when subjected to heat and pressure. The thus-formed free-flowing abrasive mixture is then coated continuously onto a flexible backing member. Afterwards, the layer of abrasive mixture is heated to cause fusion of the solid binder at the interface with the liquid binder. It is then compacted into a relatively dense abrasive layer, and is wound up into a jumbo roll in which condition the abrasive layer is subjected to further heat to cure the binder material.
