Abstract:
A bonded structure has a first substrate composed of aluminum or an aluminum alloy, a first thin film layer formed on the surface of the first substrate, and a resin adhesive layer bonded to the surface of the first thin film layer. The first thin film layer is composed of silicate glass that has a metal element with different valency from Si as a solid solution. The resin adhesive layer includes a resin including a structural site derived from ionic polymerization or a resin capable of dehydration condensation.
Abstract:
A pressure-sensitive adhesive film which is a pressure-sensitive adhesive film comprising a thermoplastic resin, wherein a maximum peak temperature of tan δ is 0° C. or more and 52° C. or less, a shear storage elastic modulus at 20° C. is 3×105 Pa or more, and a proportion of an undissolved component in dissolution of 1.0 g of the pressure-sensitive adhesive film in 10 g of isopropyl alcohol is 35% by mass or more and 100% by mass or less.
Abstract:
The present invention relates to a reinforcement mesh (1) for use in construction, the mesh (1) comprising a plurality of longitudinally and transversely extending reinforcing members (2), wherein either of the longitudinal or the transverse reinforcing members (2), each comprises a rebar comprising strands (3) of material twisted together, the strands being parted at spaced locations along their length by the other of the longitudinal or transverse rebars which extend through, and are secured at, the spaced locations of the parted strands (4). The present invention also relates to a method for producing a reinforcement mesh (1) for use in construction
Abstract:
The invention relates to a method for adhering two substrates, namely a first substrate A and a second substrate B, to each other using a latent-reactive adhesive film with at least one latent-reactive adhesive film layer which has a thermoplastic component with a melting temperature T(melt), where 35° C.≦T(melt)≦90° C., said thermoplastic component containing functional groups that can react to isocyanate, and an isocyanate-containing component that is dispersed into the thermoplastic component in a particulate form and is blocked, microencapsulated, or substantially deactivated in the region of the particle surface. The particles have a start temperature T(start) of 40° C.≦T(start)≦120° C., wherein T(start)≧T(melt). A surface of the first substrate A is brought into contact with a first surface of the latent-reactive adhesive film, and a surface of the second substrate B is brought into contact with the second surface of the latent-reactive adhesive film. The adhesion is caused by heating the latent-reactive adhesive film to a temperature which corresponds to or is higher than at least the start temperature T(start). The invention is characterized in that at least the surface of the first substrate A which is brought into contact with the latent-reactive adhesive film is treated with a primer before the first substrate A is brought into contact with the latent-reactive adhesive film, and/or at least the first surface of the latent-reactive adhesive film which is brought into contact with the first substrate A is treated with a primer before the first substrate A is brought into contact with the latent-reactive adhesive film.
Abstract:
Aqueous adhesion promoter compositions include at least one aminosilane and/or aminosiloxane and also at least one mercaptosilane. The adhesion promoter compositions are suitable more particularly as primers or adhesion-promoter undercoats for adhesives and sealants. They are especially suitable for the adhesive bonding of vehicle glazing. Exceptionally high adhesion has been found more particularly with glazing featuring applied silver prints.
Abstract:
A bonding method of silicon base members is provided. The bonding method of silicon base members comprises: applying an energy to a first silicon base member including Si—H bonds to selectively cut the Si—H bonds so that the first silicon base member is cleaved and divided to one silicon base member and the other silicon base member, and the one silicon base member having a cleavage surface and dangling bonds of silicon obtained by cutting the Si—H bonds; and bonding the cleavage surface of the one silicon base member and a surface of a second silicon base member on which dangling bonds of silicon are exposed to thereby bond the cleavage surface and the surface together through their dangling bonds.

Abstract:
A method of sealing lenses includes the steps of grinding the edges of at least two lenses, cleansing the lenses, positioning the lenses next to one another, applying an adhesive to the ground edges of the lenses and placing the lenses in an oven to cure the adhesive to produce a laminated, hermetically-sealed, lens.
Abstract:
The present invention is directed to an aqueous adhesive composition comprising a functionalized polyolefin, a cross-linking agent, and a cross-linkable resin as well as to a process for adhering a thermoplastic elastomer composition to a substrate comprising the steps of applying said aqueous adhesive composition to a polar substrate and applying the thermoplastic elastomer, for instance, by extrusion, in particular, by robotic extrusion.
