A simple, highly versatile method for fixing smooth materials that utilizes a water pasting method can be provided by interposing an ionic liquid between smooth materials such as glass or resin not impregnated with an ionic liquid and fixing these smooth materials.

A temporary sheet bonding method includes dip-coating temporary bonding layer 200 on a first sheet 100 by dipping the first sheet into a bonding solution comprising a surfactant and temporarily bonding the second sheet 300 to the first sheet via the temporary bonding layer. The surfactant includes cetyltrimethylammonium bromide or poly [(3-methyl-1-vinylimidazolium chloride)-co-(1-vinylpyrrolidone)]. A sheet dip coating apparatus includes a bonding solution bath 410 in which a bonding solution containing a surfactant is contained, a cassette 430 into which a plurality of first sheets are to be loaded, and a driver configured to move the cassette up/down. The driver sequentially moves the cassette down to immerse the first sheet in the bonding solution, the cassette up until the plurality of first sheets are removed from the bonding solution, and the cassette up and away from a surface of the bonding solution.

The present disclosure relates to laminated armor materials for enhanced ballistic protection. In particular, the present disclosure relates to laminated armor materials comprising first and second armor materials and a laminated adhesive layer comprising nanomaterial fillers.

An adhesive composition is provided that includes a block copolymer present at greater than or equal to 30 total weight percent of the adhesive system comprising a high glass transition temperature in subunits Y and Y, each of the subunits Y and Y having a high glass transition temperature of from 70 C. to 130 C. with a low glass transition temperature subunit Z having a low glass transition temperature of from 100 C. to 10 C. intermediate between said high glass transition temperature acrylate subunits to define a structure Y-Z-Y. The triblock copolymer is dissolved in a monomer curable under free radical. A free radical initiator of a peroxide or a hydroperoxide are present in combination with a sulfonyl chloride, dihydropyridine and copper or vanadium salt. By heating the cured adhesive at or above 70 C., the adhesive is amenable to being removed, repaired, or reworked.

The present invention is a method for peeling an adherend from a pressure-sensitive adhesive layer by irradiating a laminate in which the pressure-sensitive adhesive layer and the adherend are laminated with light, the peeling method includes a step of irradiating the pressure-sensitive adhesive layer with the light having a pulse width of 1 second or less and a light irradiation amount of 1,000 mJ/cm.sup.2 or more, and the pressure-sensitive adhesive layer satisfies predetermined conditions in terms of a minimum transmittance in a near-infrared region of a wavelength of 800 nm to 2,500 nm and a maximum transmittance in a visible light region of a wavelength of 380 nm to 780 nm.

An object of the present invention is to provide a sealing method using a cover film where a problem of odor is not likely to occur and quick drying properties and sealability are high. The sealing method according to the present invention is a sealing method that is performed using at least a cover film and a sealing solvent, the cover film including a polymer layer provided on a transparent support, in which the sealing solvent is a solvent including at least one kind selected from the group consisting of an ester, an alcohol, a ketone, an ether, and an aromatic hydrocarbon, in a case where the sealing solvent is an ester, an alcohol, a ketone, or an ether, a boiling point of the sealing solvent is 80 C. to 170 C., and in a case where the sealing solvent is an aromatic hydrocarbon, a boiling point of the sealing solvent is 150 C. to 170 C.

Composite materials that are especially recyclable, the composite materials having at least two material layers bonded by a layer of adhesive. For an easy and clean separation of the two material layers the adhesive consists of a material that loses its adhesive effect when introduced into a weakly acidic solution.

The present invention relates to a method of producing an ionomer resin particulate, comprising a step of extruding a mixture comprising a crude ionomer resin and a solvent, cooling the extruded mixture, and solidifying the crude ionomer resin in the mixture to obtain a porous particulate, wherein the crude ionomer resin comprises a (meth)acrylic acid unit (A), a neutralized (meth)acrylic acid unit (B) and an ethylene unit (C), a total amount of the unit (A) and the unit (B) is 6 to 10 mol % based on all monomeric units constituting the crude ionomer resin, and a porosity of the particulate is 60% or more.

An adhesive composition for a glass article includes polyvinyl butyral (PVB) and at least one expansion device. There is also provided an automotive laminated glazing including at least two glass sheets, and as lamination interlayer, a layer of such an adhesive composition, and a method for obtaining such a laminated glazing and for disassembling same, including heating the automotive laminated glazing at a temperature between 110 C. and 260 C. for a period of between 0.5 and 10 minutes.

A polyol composition suitable for making rigid polyurethane foam includes a combination of five polyols, a surfactant and a polyurethane gelling catalyst. The polyol composition contains at most a very small quantity of a blowing catalyst. The polyol composition surprisingly produces, upon reaction with a polyisocyanate in the presence of a physical blowing agent, a polyurethane foam that exhibits little or no loss of compressive strength when overpacked. The polyol composition is especially useful for making fiber-reinforced rigid foams useful in cryogenic applications.
