The present disclosure provides an oil-resistant adhesive comprising a crosslinked copolymer of (meth)acrylic ester monomers, methyl (meth)acrylate monomers, vinyl ester monomers, and a functional monomer selected from one of (meth)acrylic acid, a (meth)acrylamide or a hydroxyalkyl (meth)acrylate monomers.

Disclosed is a composition comprising: a) an condensate of one or more aminohydrocarbyl alkoxy silanes and one or more alkenyl alkoxy silanes; b) one or more mercaptohydrocarbyl alkoxy silanes; and c) water; wherein the composition is useful as a primer useful with adhesives or coatings containing polymers having isocyanate functional groups, alkoxysilane functional groups or both. The composition may include one or more epoxyhydrocarbyl silanes. The composition may include one or more alkanols in sufficient amount to improve the volatilization of the liquid components away from substrate surface.

To provide an aqueous adhesive for an inorganic material with excellent adhesiveness to the inorganic material. An adhesive improver (J) for an aqueous adhesive for an inorganic material including a copolymer (A) containing an unsaturated (poly) carboxylic acid (anhydride) (a1) and a (meth) acrylic acid alkyl (2 to 30 alkyl carbon atoms) ester (a2) as a constituent monomer; and an aqueous adhesive for an inorganic material (X) including the adhesive improver (J), saccharide (B), a polycarboxylic acid (C) having 4 to 24 carbon atoms and water.

Disclosed are an anti-sticking adhesive tape for molding of a composite material and a manufacturing method therefor and the use thereof, the anti-sticking adhesive tape including the following sequentially laminated structures: a first layer being a fluorine-containing resin layer, a second layer being a first adhesive layer, a third layer being a reinforcing material layer, and a fourth layer being a second adhesive layer, wherein the bonding force between the first layer and a resin for molding of a composite material is smaller than the 180-degree peeling adhesion force of the fourth layer, and the intermolecular cohesive force of the first adhesive layer and the intermolecular cohesive force of the second adhesive layer are both larger than the 180-degree peeling adhesion force of the fourth layer. The anti-sticking adhesive tape can easily be separated from the resin for molding of a composite material when opening the mold.

A tempered glass protective film for ultrasonic fingerprint recognition function is configured to solve the problem that the echo energy received by the ultrasonic fingerprint sensor is low and the clear fingerprint image cannot be obtained after the tempered glass protective film is used on the electronic device. The tempered glass protective film includes a glass layer, a first glue layer and a second glue layer arranged in a top-to-bottom sequence, in which the first glue layer is an OCA glue layer, and the second glue layer is a silicone layer or a PU glue layer. The thickness of the OCA glue layer gradually decreases from the edge to the center, and correspondingly, the thickness of the tempered glass protective film gradually decreases from the edge to the center. The tempered glass protective film has better impact resistance while improving the echo energy received by the ultrasonic fingerprint sensor.

An anti-wear composite structure includes an anti-wear layer that has a wear surface opposite an adhesive receiving surface and a thermosetting resin applied to the adhesive receiving surface. The thermosetting resin includes a reactive adhesive configured to bond the anti-wear composite structure to a substrate at an ambient temperature band via pressure-sensitive adhesion. The thermosetting resin has an onset to cure in the ambient temperature band and has a peak cure temperature greater than the ambient temperature band to mechanically and chemically bond the anti-wear composite structure to a substrate.

The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

A self-disinfecting photocatalyst sheet includes a substrate material and a photocatalyst layer with a primary photocatalyst and a secondary photocatalyst. The primary photocatalyst is a metal oxide photocatalyst, whereas the secondary photocatalyst is a metallic photocatalyst. The substrate material binds the photocatalyst layer by either connecting a metal ion of the primary photocatalyst and/or the secondary photocatalyst through two oxygen atoms of a carboxyl group (COO), or by forming hydrogen bonds between a carbonyl group and a surface hydroxyl group (OH.sup.) of the primary photocatalyst. The self-disinfecting photocatalyst sheet is activatable by a visible light and can self-disinfect against bacteria and viruses.

A waterproof sheet which is for application to a site to be waterproofed in order to prevent rainwater infiltration thereinto and retard deteriorations which proceed with time, the waterproof sheet comprising: a base layer that comprises a silicone rubber composition reinforced with reinforcing fibers and that has physical properties including high strength; and a pressure-sensitive silicone adhesive layer that has been formed on one surface of the base layer and that has a low hardness and is highly tacky. The waterproof sheet provided by the present invention less breaks than conventional waterproof sheets because of the reinforcement layer, and can conform to cracks or dislocations occurring in the surfaces to which the waterproof sheet has been applied, due to the pressure-sensitive adhesive layer formed on one surface. Since the waterproof sheet includes silicones as main components and is hence excellent in terms of weatherability, heat resistance, and freeze resistance, this waterproof sheet can retain the function required of waterproof sheets, over a longer period.

An adhesive tape for application to a component of a motor vehicle, consisting of a primer layer having a self-adhesive lower side and a self-adhesive upper side, where the primer layer is embodied such that it is activatable for chemical reaction with an adhesive. The use of an adhesive tape, to an assembly, and to a method is also provided.
