Abrasive Composites Having A Controlled Rate Of Erosion, Articles Incorporating Same, And Methods Of Making And Using Same

View page
US Patent:
55185126, May 21, 1996
Filed:
Jun 1, 1994
Appl. No.:
8/252418
Inventors:
Louis D. Hibbard - Eagan MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
B24D 302
US Classification:
51308
Abstract:
An abrasive composite is presented having a controller rate of erosion, the composite comprising abrasive particles dispersed in the binder, wherein the binder comprises an addition polymerized resin having clay particles dispersed therein. The abrasive composite may be adhered to various substrates, including paper, cloth, polymeric films, and nonwovens. The clay particles allow the binder, and thus the composite, to controllably erode upon abrasion of a workpiece, thus exposing fresh abrasive particles to the workpiece. Coatable compositions comprising clay particles dispersed in a binder precursor composition, and optionally containing abrasive particles, are also described, as well as methods of making and using the composites and articles.

US Patent:
54548446, Oct 3, 1995
Filed:
Oct 29, 1993
Appl. No.:
8/145404
Inventors:
Louis D. Hibbard - Eagan MN
Stanley B. Collins - White Bear Lake MN
John D. Haas - Woodbury MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
B24D 300
B24D 1100
US Classification:
51295
Abstract:
An abrasive article having a sheet-like structure having a major surface and having deployed in a fixed position thereon a plurality of abutting abrasive composites in an area spacing of at least 1,200 composites/cm. sup. 2, each of the composites comprising a plurality of abrasive particles dispersed in a binder. The invention also relates to a method for reducing a surface finish of a workpiece surface using the abrasive article and a process for making the abrasive article of the invention.

US Patent:
56675410, Sep 16, 1997
Filed:
Nov 21, 1996
Appl. No.:
8/753208
Inventors:
Thomas P. Klun - Lakeland Township, Washington County MN
Louis D. Hibbard - Eagan MN
Kathryn M. Spurgeon - River Falls MN
Scott R. Culler - Burnsville MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
C09K 314
US Classification:
51298
Abstract:
Coatable compositions suitable for use in producing abrasive articles are presented. The inventive coatable compositions comprise a free radically polymerizable composition, abrasive particles, and a photoinitiator system. The photoinitiator system consists essentially of a compound which cleaves via. alpha. -cleavage and has a molar absorptivity in dilute methanol solution ranging from about 4 to about 400 liter/mole-cm in at least some portion of the UV/visible spectrum ranging from about 395 and about 500 nanometers. Abrasive articles incorporating cured versions of the compositions are presented, as well as methods of making and using the articles.
