A membrane composite comprising a polymeric membrane panel, an adhesive layer, and a release member, where the adhesive layer is a pressure-sensitive adhesive that is at least partially cured, and where the adhesive layer has a thickness of at least 102 m

A sensor for emitting or receiving light rays includes a clear substrate having a first surface, and an applique attached to the first surface of the clear substrate. The applique includes a transparent fluoropolymer sheet of fluorinated ethylene propylene having a first surface facing the first surface of the clear substrate, and a pressure sensitive optically clear acrylic adhesive disposed on the first surface of the fluoropolymer sheet. The pressure sensitive acrylic adhesive adheres the transparent sheet to the first surface of the clear substrate, and exhibits a peel strength of between 1 and 3 lbs/in. The first surface of the fluoropolymer sheet is treated for adhesion prior to applying the pressure sensitive acrylic adhesive thereto.

C. and a density of from 945 to 960 kg/m3, composed of: B11) 65% to 85% by weight of ethylene homopolymer, and B12) 15% to 35% by weight of ethylene/C4-C12 alpha-olefin copolymer; B2) 11% to 30% by weight of propylene terpolymer; B3) 4% to 15% by weight of polyethylene elastomer (ethylene/C4-C12 alpha-olefin copolymer); c) a middle polymer layer (C) containing: C1) 61% to 80% by weight of propylene terpolymer; C2) 15% to 25% by weight of styrene block copolymer elastomer; C3) 5% to 19% by weight of polyethylene elastomer.

A membrane composite comprising a polymeric membrane panel, an adhesive layer, and a release member, where the adhesive layer is a pressure-sensitive adhesive that is at least partially cured, and where the adhesive layer has a thickness of at least 102 m.

A roof system comprising a roof substrate, a first membrane including first and second opposed planar surfaces, and a second membrane including opposed first and second planar surfaces, where said second membrane is adhered to said roof substrate through an adhesive disposed on said roof-substrate contacting portion of the first membrane, and where said second membrane is adhered to said first membrane through said adhesive disposed on a lap portion of said second membrane.

A composite comprises: at least one reinforcing element (10), an adhesive layer (14) made from an adhesive composition and coating the reinforcing element (10), an elastomeric bonding layer (16) made from an elastomeric bonding composition and directly coating the adhesive layer (14), and an elastomeric body made from an elastomeric matrix and embedded in which is the reinforcing element (10) coated with the adhesive layer (14) and with the elastomeric bonding layer (16). The adhesive composition comprises a phenol-aldehyde resin based: on an aromatic polyphenol comprising at least one aromatic ring bearing at least two hydroxyl functions in the meta position relative to one another, the two positions ortho to at least one of the hydroxyl functions being unsubstituted; and on an aromatic aldehyde bearing an aldehyde function, comprising at least one aromatic ring.

A method for treating substrates, including applying a composition, which includes at least one latent alkyl borane and is substantially free of decomplexing agents for the latent alkyl borane, to a substrate (1) that has a material having unsaturated units, applying a radically curable substance to the substrate (1) pretreated with the latent alkyl borane, and allowing the radically curable substance to cure in order to form a composite structure. The method is suitable in particular for applying paints, coatings, or sealing materials/filling materials to substrates, such as EPDM, NBR, and SBR, and for adhesively bonding such substrates. Composite materials adhesively bonded accordingly are distinguished by especially firm adhesion of the adhesive to the substrate, wherein conventional adhesives can be used, which have optimized properties with regard to the storage stability, open time, and cure time thereof.

A membrane composite comprising a polymeric membrane panel, an adhesive layer, and a release member, where the adhesive layer is a pressure-sensitive adhesive that is at least partially cured, and where the adhesive layer has a thickness of at least 102 m.
