An abrasive article, for example, a coated, bonded, or nonwoven abrasive article comprising a binder, a plurality of abrasive particles, and an antiloading component.
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:
Novel compounds which are 2,6-di-tertiary-butylphenols substituted in the 4 position by an acylaminophenyl group, which acylaminophenyl group is substituted by a moiety which includes a carboxyl group, are useful as inhibitors of leukotriene biosynthesis and as antiallergic agents.
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:
An abrasive article is provided that includes at least one binder system formed from a polymeric additive and a thermosetting resin. The polymeric additive includes a polymeric backbone having substituents attached thereto, wherein the substituents include at least one urethane linked nitrogen bonded side chain having about 5 carbon atoms or more and a terminal methyl group and at least one oxygen linked water solubilizing group. An abrasive article that includes the binder system exhibits an increase of workpiece surface abraded in a Woodsanding Normal Force Test as compared to an abrasive article including a binder system formed from a composition containing substantially no polymeric additive.
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.
