Abstract
The present invention involves the use of powder coating methods to form coated abrasives. In one embodiment, the powder is in the form of a multiplicity of binder precursor particles comprising a radiation curable component. In other embodiments, the powder comprises at least one metal salt of a fatty acid and optionally an organic component that may be a thermoplastic macromolecule, a radiation curable component, and/or a thermally curable macromolecule. In either embodiment, the powder exists as a solid under the desired dry coating conditions, but is easily melted at relatively low temperatures and then solidified also at reasonably low processing temperatures. The principles of the present invention can be applied to form make coats, size coats, and/or supersize coats, as desired.
