  • Patent number: 11773247
    Abstract: The present invention relates to an impregnation process for a fibrous substrate, a liquid composition for implementing this process and the obtained impregnated fibrous substrate. The impregnated fibrous substrate is suitable for manufacturing mechanical or structured parts or articles. In particular the present invention deals with an industrial process for impregnating a fibrous substrate or long fibers with a viscous liquid composition containing mainly methacrylic or acrylic components. This viscous composition is called hereafter liquid (meth) acrylic syrup. The invention concerns also a fibrous substrate pre-impregnated with said syrup which is useful for manufacturing mechanical or structured parts or articles. More particular the impregnation of fibrous substrate with the (meth) acrylic syrup is achieved in a closed mould.

  • Patent number: 10519351
    Abstract: A method includes preparing a solvent, adding the solvent into a mixture to dissolve the mixture and to form a mixing solution, adding a filler and an additive into the mixing solution, and using a three-shaft mixer to stir and blend the solvent, the filler, the mixing solution and the additive to form a sticky quick drying adhesive. The temperature is controlled under 40° C. in the above steps. The solvent includes heptane, acetone, N-hexane and toluene which are mixed in a predetermined weight proportion. The mixture includes C9 hydrocarbon resin, C5 and C9 co-polymer hydrocarbon resin and styrene-butadiene. The filler includes calcined kaolin, calcium carbonate, anti-oxidant and fumed silica. The additive includes monoethylene glycol. Thus, the quick drying adhesive is extruded outward at a low temperature state (?15° C.).

  • Patent number: 9988509
    Abstract: Cellulose cyanoacrylate is employed either to bond two surfaces or to duplicate the shape of a three-dimensional object. The method is carried out by applying a release material to the object to be duplicated, applying a sheet of cellulosic material formed of wood fibers onto the three dimensional object, then saturating the sheet of cellulosic material with a cyanoacrylate glue and permitting the saturated sheet to cure. The resulting product duplicates the shape of the object. Two surfaces may be bonded by placing a sheet of cellulosic material between the two surfaces and applying the cyanoacrylate glue to edges of the sheet until saturated and allowing it to cure. Paper toweling may favorably be employed as the cellulosic material. This material may also be employed in bone or tooth repair. A break or fracture in an article can be repaired by positioning a sheet of cellulosic material over the break, saturating it with cyanoacrylate glue, and holding the saturated sheet in place with a releasable film.

Embodiments the closures indicate that vessel contents have reached at least a predetermined temperature. The proof of treatment closures can show that vessel contents a distance within the vessel interior have reached the threshold conditions, rather than reflecting conditions of the vessel itself, or of vessel contents in close proximity to a vessel peripheral boundary. Embodiments include proof of treatment closures resistant to status tampering, such that it is difficult to activate the indicator without reaching the specified conditions. The proof of treatment closures can also be seal tamper evident, such that loosening or removing the closure from the vessel, or otherwise breaking a seal between the closure and the vessel, leaves conspicuous evidence of such.

The aqueous-based adhesive compositions are particularly effective at preventing the buildup of static charge and at reducing electrostatic discharge events. In certain aspects, the aqueous-based adhesive compositions can be mixed with propellants and applied to substrates using an aerosol delivery system. The aqueous-based adhesive compositions described herein can readily be adhered to any substrate such as, for example, floors, walls, ceilings, and the like.

  • Patent number: 8734939
    Abstract: The invention relates to a thermally reversible hot melt adhesive that is isocyanate-free, moisture independent, crosslinkable and thermally reversible. The thermally reversible hot melt adhesive may be repeatedly heated and cooled without negatively affecting the performance of the adhesive. The thermally reversible composition may also be used as a primer layer. The thermally reversible hot melt adhesive and primer are particularly well suited for end use applications such as packaging, graphic arts, construction, footwear, textiles, general assembly, automotive and consumer goods.

  • Publication number: 20140133030
    Abstract: Attachment methods for daylighting sheets and a resulting optical construction enable daylighting microstructures to be secured to a light incident surface, such as a glazing. Applying an adhesive to selected portions of the daylighting microstructures creates a transparent, optical adhesive surface that enables the daylighting microstructures to be oriented outward, facing the incident light, and effectively seals the microstructures against the glazing to prevent ingress of dust and contaminants that would degrade optical efficiency.

  • Publication number: 20140134439
    Abstract: A method for solvent-less adhesive bonding is provided comprising depositing thin, functional, polymeric films on one or more substrates and bonding the substrates to each other or to other substrates. Depositing the polymeric films, including, for example, chemically reactive polymers and thermoplastics with adhesive qualities, may be accomplished using an initiated chemical vapor deposition technique compatible with a variety of monomers, including monomers with chemically functional moieties such as amine and epoxy groups. The technique allows for deposition of polymeric films on a wide variety of substrates/devices and provides an alternative for other coating/deposition methods that are incompatible with certain substrates/devices and/or do not provide adequate control over the resulting polymeric film. The provided method is advantageous in that it is applicable to fabrication of hybrid devices and is compatible with microfabrication technology, including that in clean-room settings.
