摘要:
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.

摘要:
Organic compounds having at least one ethylenically-unsaturated group are described, the organic compounds being suitable for use in coatable compositions as reactive diluents; compounds of the invention preferably have a divalent organic linking moiety devoid of reactive groups other than optional ethylenically-unsaturated groups, and a polar organic moiety and are particularly adept in solubilizing aminoplast resins having radiation-curable pendant groups.

摘要:
Abrasive articles made using a coatable, addition polymerizable binder precursor composition are described, as well as methods of making same. The compositions comprise a reactive diluent compound and preferably an addition polymerizable resin, the reactive diluent being an organic compound selected to be especially effective in solubilizing aminoplast resins.
