The present invention is directed to a method of making a three-dimensional fixed abrasive article, and a three dimensional fixed abrasive made thereby. The method comprises providing an abrasive composition comprising a plurality of abrasive particles and a binder precursor. The binder precursor comprises a polymerizable material consisting essentially of an ethylenically unsaturated material having one or more terminal functional groups of the same type of reactive functionality, a photoinitiator, and a thermal initiator. The abrasive composition is then applied onto a backing. The method then comprises at least partially curing the binder precursor by activating the photoinitiator, and further curing the binder precursor by activating the thermal initiator to provide a three-dimensional fixed abrasive.

Dual cured abrasive articles

An energy sensitive composition comprising a monomeric organometallic complex essentially free of nucleophilic groups and which, upon exposure to energy, bonds to basic reactive sites on a substrate via the metal center, leaving the polymerizable group of the complex unreacted and unrestricted; an energy sensitive composition at least one energy sensitive organometallic group is incorporated in or appended to the backbone of a polymer, such that the resulting coordinatively unsaturated organometallic group or groups bond to basic reactive sites on a substrate, thus forming permanent bonds, and further, the adherent compositions are useful in applications such as adhesion of polymers to substrates, protective coatings, printing plates, durable release coatings, primers, binders, and paints.

Organometallic monomers and polymers with improved adhesion

Abrasive article comprising organometallic coupling agent

A process for making an adhesive comprising allowing a carrier web coated with a thermal free-radically polymerizable mixture to remain in a heat exchange medium for a time sufficient to subdue the reaction exotherm and maintain a reaction temperature by thermal contact of the polymerizable mixture with the heat exchange medium and to affect conversion of the coating to an adhesive layer, preferably to a pressure sensitive adhesive layer, wherein the coating is a substantially solvent-free thermally initiated polymerizable mixture comprised of at least one free radical monomer, at least one thermal initiator, optionally, at least one cross-linker and optionally, at least one co-monomer.

Opaque adhesives and method therefor

Process of making thermal free-radical cure adhesives

A curable pressure sensitive adhesive having long shelf stability comprising (a) at least one free radically polymerized polymer; (2) at least one cationically-polymerizable monomer; (3) a photo-activatable catalyst system for the cationically-polymerizable monomer comprising either at least one organometallic complex salt or at least one onium salt; and (4) optionally, a monohydric or polyhydric alcohol, wherein there is essentially no conversion of the cationically-polymerizable monomer of the curable pressure sensitive adhesive when stored in a manner to exclude actinic radiation, and methods of making the same.

Stable, low cure-temperature semi-structural pressure sensitive adhesive

The present invention provides a pressure-sensitive adhesive composition and a method for producing the same. The pressure-sensitive adhesive composition is produced by the combination of at least one free-radically photopolymerizable monomer and at least one cationically polymerizable monomer and a suitable photoinitiation system consisting of at least one salt of a cationic organometallic complex, an optional additional free-radical initiator and the application of sufficient energy to photopolymerize same.

Energy curable cationcally and free-radically polymerizable

A process for polymerizing a free-radically polymerizable composition comprising the steps:

Polymerization of systems using a deoxygenated medium

The present invention provides a pressure-sensitive adhesive composition and a method for producing the same. The pressure-sensitive adhesive composition is produced by the combination of at least one free-radically photopolymerizable monomer and at least one set of polyurethane precursors, and a suitable photoinitiation system consisting of at least one salt of a cationic organometallic complex, an additional free-radical photo initiator and the application of sufficient energy to photopolymerize same by sequential exposure to visible electromagnetic radiation and then to ultraviolet electromagnetic radiation.

Energy curable pressure-sensitive adhesive compositions

A method for preparing a coated abrasive article wherein the a plurality of abrasive grains are applied to a make coat such that the abrasive grains are substantially a mono-layer. The make coat precursor is a pressure-sensitive adhesive-like or pressure-sensitive adhesive. The make coat precursor is partially cured to approximate a pressure-sensitive adhesive-like layer or when fully cured is a pressure-sensitive adhesive. The make coat precursor has sufficient 'tack' to hold the abrasive grains during the application and curing of the size coat, resulting in a substantially monolayer of abrasive grains.
