A method for surfacing a polymeric composite article and/or for joining (for example, by bonding or by co-curing) the article and an adherend (for example, a second polymeric composite article) comprises

Surfacing and/or joining method

Fibers comprising a first thermoplastic composition having a softening temperature up to 120&#xb0; C and a curable resin. Also disclosed are compositions comprising a plurality of fibers, with some of the fibers comprising a first thermoplastic composition having a softening temperature up to 120&#xb0; C and some of the fibers comprising a curable resin. The fibers have an aspect ratio of at least 2:1 and a maximum cross-sectional dimension up to 60 micrometers. Fluid compositions containing the fibers and methods of contacting a subterranean formation using the fibers are also disclosed.

Curable fiber

Methods of preparing silicone materials using electron beam curing are described. The materials are hot melt processed and cured in the absence of an effective amount of catalysts and initiators. Both functional and nonfunctionalized silicone materials may be used. Exemplary cured materials include silicone pressure sensitive adhesives, silicone foams, and non-tacky silicon films.

Electron beam cured silicone materials

Electron beam and gamma radiation crosslinked, silicone gel adhesives are described. Both nonfunctional and functional poly diorganosiloxanes are used. Methods of forming the adhesives, and medical articles incorporating such adhesives are also described.

Gentle to skin adhesive

Methods of electron beam curing nonfunctional polysiloxanes and silanol terminated polysiloxanes are described. The resulting release materials are also described.

Electron beam cured silicone release materials

The invention provides a method for imparting topographical or protective features to a substrate by contacting a sheet material comprising a thermosettable layer with a substrate and heating the sheet material to an elevated temperature.

Melt-flowable materials and method of sealing surfaces

Curable mechanical fasteners of the invention comprise a fastening surface comprising a curable material, wherein the fastening surface is capable of being repeatedly attached and unattached to a complementary fastening surface, and when attached to the complementary fastening surface and cured, the curable mechanical fastener is capable of becoming permanently attached to the complementary fastening surface. The curable mechanical fastener may also further comprise the complementary fastening surface.

Curable mechanical fasteners

A multi-layered article for establishing a seal between two substrates. The multi-layered article includes a bulk layer and an adhesive layer. The layers of the article are generally epoxy-containing, photo-activated materials. Upon photo activation, the bulk layer and the adhesive layer have different curing rates. The article is suitable for adhering and sealing two substrates together. The article is particularly useful when at least one of the substrates is glass.

Multi-layered sealant

The invention provides polyepoxide-based adhesives containing cycloaliphatic-containing polyepoxide resin, aromatic polyepoxide resin, and 9,9-bis(3-methyl-4-aminophenyl)fluorene. The adhesives provide improved peel and shear strength.

High temperature epoxy adhesive films

The invention provides a method for imparting topographical or protective features to a substrate by contacting a sheet material comprising a thermoplastic layer with a substrate and heating the sheet material to an elevated temperature. The invention also provides a sheet material which comprises at least one layer consisting essentially of one or more thermoplastic, melt-flowable polymers that are semi-crystalline at room temperature.

A multi-layer article which may be provided in the form of a tape comprises a conformable, compressible, melt flow-resistant core layer having first and second major surfaces, a sealant layer on the first major surface of the core layer, and optionally a bonding layer on the second major surface of the core layer. The sealant layer and the bonding layer each have a surface available for contacting a separate substrate. Various thermoset and foam core layers are disclosed as are thermosettable and thermoplastic sealant layers. The articles are useful for sealing two substrates together, particularly where one of the substrates is glass. Thus, the articles are especially adapted for sealing motor vehicle windshields to a frame. Various assemblies and methods for producing the same are also described.

Sealant composition, article including same, and method of using same

A coated abrasive article comprises a backing, a first binder on the backing, and a plurality of abrasive particles in the first binder. The first binder precursor is an energy-curable preferably, melt-processable resin containing an epoxy resin, an ethylene-vinyl acetate copolymer, and a curing agent for crosslinking the epoxy resin that is cured to provide a crosslinked make coating. The above binder precursors of the invention are preferably free of homopolymers and copolymers of olefinic monomers. In another aspect, the invention also describes an energy curable first binder precursor containing an epoxy resin, an ethylene-vinyl acetate copolymer, a polyfunctional acrylate component and a curing agent for crosslinking the epoxy resin that is cured to provide a crosslinked make coating. The invention also relates to a method of producing such coated abrasive articles and a surface-treated backing material.
