The PSA layer has a light transmittance of 20% or lower and an L* value of 20 or higher and 70 or lower, defined in the L*a*b* color space.

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

The invention relates to a method for producing an electrical sheet pack using an anaerobically curing adhesive, to an electrical sheet pack produced or producible by such a method, and to a device for creating an electrical sheet pack of the invention.

Disclosed herein is a solvent-based bonding primer composition containing one or more organic solvents, one or more epoxy resins, one or more curing agents, a silane compound, and a low amount of core-shell rubber particles in nanometer size, submicron or micron size. Also disclosed is a method of applying the solvent-based bonding primer composition onto a metallic surface of a first substrate prior to bonding the metallic surface to a second substrate via a curable adhesive.

Provided is a pressure-sensitive adhesive sheet which has such light-transmitting properties that the pressure-sensitive adhesive sheet hides an adherend and the surface of the adherend can be inspected through the pressure-sensitive adhesive sheet. The pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer contains at least two colorants. The pressure-sensitive adhesive sheet has a total light transmittance of 5% or greater. The pressure-sensitive adhesive layer has a haze of 20 or greater.

To provide a composite laminate having excellent adhesiveness to a resin material imparted to a metal base material, such as an aluminum, and a method for producing the same, and a metal-resin bonded article using the composite laminate and a method for producing the same. A composite laminate 1 includes a metal base material 2 and one layer or plural layers of a resin coating layer 4 laminated on the metal base material 2, the resin coating layer 4 is laminated on a surface-treated surface of the metal base material 2, and at least one layer of the resin coating layer 4 is formed of a resin composition containing an in situ polymerizable phenoxy resin.

A B-stage thermoset adhesive composition comprises components a) and b) in respective amounts of 10 to 40 percent by weight to 60 to 90 percent by weight. Component a) comprises at least one thermoplastic elastomer comprising a styrenic block copolymer. Component b) comprises a polymerized reaction product of at least one capable of undergoing ring-opening metathesis polymerization and at least one ring-opening olefin metathesis catalyst. A composite article including the B-stage thermoset adhesive and methods of making the composite article are also disclosed.

The present disclosure provides a process for forming a laminate. The process includes (A) uniformly applying an isocyanate component to a first substrate, the isocyanate component containing an isocyanate compound; (B) uniformly applying an isocyanate-reactive component to a second substrate, the isocyanate-reactive component containing an amine-terminated compound; (C) bringing the first substrate and the second substrate together, thereby mixing and reacting the isocyanate component and the isocyanate-reactive component to form an adhesive composition between the first substrate and the second substrate; (D) curing the adhesive composition to bond the first substrate and the second substrate; and (E) forming the laminate.

A method of gluing a first metal part to a second part includes the steps of providing a first metal part such as a steel part, and the second part such as a second metal part, treating a surface portion of the first metal part intended for being glued to the second part with laser pulses so that a surface layer of the first metal part across the surface portion is removed, preferably by ablation, while applying laser pulses to the surface portion of the first metal part also applying a pressurized air or gas stream to the surface portion, applying an adhesive to at least the surface portion of the first metal part and/or to a surface of the second part, and gluing the first metal part and the second part together.

Liquid epoxy-based adhesive compositions are provided, which upon curing result in crash durable and stress resistant cured bonds on both steel and other materials, in particular metals such as aluminum; and in some embodiments are weldable in an uncured state; also provided are bonded assemblies comprising the cured epoxy-based adhesives, methods of making the liquid epoxy-based adhesives, methods of bonding assemblies and articles of manufacture comprising the bonded assemblies.
