摘要:
A production method of a laminate including a substrate and a light-transmitting support plate that are laminated each other via an adhesive layer and a release layer that is altered through absorption of light, the method including a release layer forming step of coating a reactive polysilsesquioxane on a surface of the support plate, the surface being opposed to the substrate, and heating the reactive polysilsesquioxane to perform polymerization, thereby forming the release layer.
摘要:
Reworkable adhesive that has a high shear strength through a range of use temperatures but which has a low strength and is reworkable at a suitable processing temperature.
摘要:
Adhesives suitable for preparing laminates of polyvinyl chloride or polyvinyl chloride copolymers with wood or metal are prepared from a three component polymer mixture of polyvinyl chloride or its copolymers itself, a direct ethylene copolymer and another direct ethylene copolymer containing units derived from a monomer containing glycidyl units. The adhesive is especially useful for preparing PVC/wood laminates which are subject to outdoor weathering.

摘要:
Thermosetting adhesive compositions formed from an epoxy resin containing nano-sized core-shell particles, one or more thermoplastic toughening agent containing an amine-terminated polyethersulfone, and at least one multi-functional epoxy resin, together with at least one amine curing agent to allow full cure of the adhesive composition up to 400° F. are provided herein. Such compositions are useful for forming adhesive films that can bond composite/metal/honeycomb structures for aerospace including bonding of aircraft leading or trailing edges, acoustic nacelle structures, horizontal and vertical tail, and various other structures, as well as for other high performance industrial applications.
摘要:
A solid surface is coated with, or bonded to another surface by means of, an adhesive composition comprising an aromatic polysulphone which has a reduced viscosity of at least 0.3 and which contains at least 0.2 (desirably 0.5 to 3.5) hydroxyl groups per 100 polymer repeat units.
摘要:
The invention provides an aromatic polysulfone including an aromatic polysulfone having at least one highly polar functional group at its terminus, wherein in the aromatic polysulfone, an area of a signal attributed to the aromatic polysulfone having a highly polar functional group with respect to a total area of all signals attributed to the aromatic polysulfone in a chromatogram obtained by measurement through a gel permeation chromatography method under the following conditions is 19% or more and 100% or less, wherein sample injection volume is 5 μL, column is “Shodex KF-803” manufactured by Showa Denko K.K., column temperature is 40° C., eluent is N,N-dimethylformamide, eluent flow rate is 0.5 mL/min, and detector is ultraviolet-visible spectrophotometer (UV).
摘要:
Provided are a thermosetting adhesive composition excellent in storage stability, reliability, and low-temperature adhesion properties; and a curl-resistant heat-resistant film and a wiring film obtained using the composition. The thermosetting adhesive composition includes 100 parts by weight of a phenoxy resin having a bisphenol S skeleton in the structure thereof; 5 to 30 parts by weight of a maleimide compound containing a plurality of maleimide groups in the structure thereof; and 3 to 20 vol % of an inorganic needle-like filler. The heat resistant adhesive film is obtained by applying the thermosetting adhesive composition onto a polyimide film, followed by drying. The wiring film is obtained by placing a conductor wiring layer on the heat resistant adhesive film.
