A composition includes methyl methacrylate MMA, at least one elastomer or a core-shell polymer, and at least one radical former, as an adhesive, sealant or coaling for gluing, sealing or coaling substrates containing plasticized PVC.

A reactive pressure sensitive adhesive composition is disclosed. A tape formed using the reactive pressure sensitive adhesive is also disclosed. In its cured state, the pressure sensitive adhesive shows superior mechanical and electrical properties compared to conventional, non-curable charge collection tapes. The tape has a cure profile pre-selected to correspond to that of a photovoltaic cell fabrication process, such that curing can take place during cell fabrication and may occur simultaneously with one or more other curing steps employed in cell fabrication.

An object of the present invention is that the migration of a plasticizer is suppressed while high bond strength is ensured. An adhesive composition of the present invention includes an acrylic polymer (A), a tackifier resin (B) and a crosslinking agent (C). The acrylic polymer (A) includes units derived from a (meth)acrylic acid alkyl ester (a1), a nitrogen-containing (meth)acrylic monomer (a2) and a carboxyl-containing (meth)acrylic monomer (a3). The content of the tackifier resin (B) is not less than 20 mass % of the content of nonvolatile components. Not less than 40 mass % of the tackifier resin (B) is represented by a rosin tackifier resin (b1).

A pressure-sensitive adhesive tape X of the present invention is a pressure-sensitive adhesive tape for a wire harness, for bundling or fixing a wire harness, and includes a substrate 10, and a pressure-sensitive adhesive layer 20 disposed at one side in a thickness direction of the substrate 10. The substrate 10 has a thickness of 85 μm or less. The pressure-sensitive adhesive layer 20 has a thickness of 55 μm or more.

The present invention relates to a corrosion prevention tape for wrapping an irregular pipe section, the tape comprising: (i) an adhesive component, the adhesive component comprising: from 10 to 50 wt % functionally modified elastomer, and from 0.1 to 20 wt % discrete reinforcing strands dispersed within the adhesive component; and (ii) a backing layer for the adhesive component.

Provided are a pressure-sensitive adhesive composition, a protective film, an optical device, and a display device. The pressure-sensitive adhesive composition may exhibit excellent storage stability, suitable low speed and high speed peel-off strengths after a crosslinking structure is formed, and have an excellent balance between them. Accordingly, the pressure-sensitive adhesive composition may exhibit an excellent protective effect when applied to a protective film, may be easily peeled in high speed peel-off and thus advantageous for a high speed process, and may exhibit an excellent antistatic property in the process.

A layered stack is created by placing webs of adhesive on opposite sides of web of cushioning layer and placing outer webs outside the webs of adhesive. An outer surface of a rotating drum is heated by heating oil inside the drum. An endless belt is heated by at least one heater. The layered stack is pulled between the heated endless belt and the heated rotating drum via a motorized drive assembly which rotates the endless belt. Both sides of the layered stack are heated enough to melt each web of adhesive when the layered stack passes between the heated moving endless belt and the heated rotating drum.

A pressure-sensitive adhesive composition, a protective film, an optical element and a display device are provided. The pressure-sensitive adhesive composition has excellent storage stability, exhibits proper low-speed and high-speed peel strengths after formation of a cross-linked structure, and also has an excellent balance between the low-speed and high-speed peel strengths. Therefore, when the pressure-sensitive adhesive composition is applied to a protective film, the pressure-sensitive adhesive composition can have an excellent protective effect, and can also be advantageous to perform a high-speed process since the pressure-sensitive adhesive composition is easily peeled during a high-speed peeling process. In the high-speed peeling process, the pressure-sensitive adhesive composition can exhibit excellent antistatic characteristics.

An adhesive film, an adhesive composition for the same, and a display member including the same are disclosed. The adhesive film includes a cured product of an adhesive composition, which includes a (meth)acrylic copolymer formed from a monomer mixture including (a1) an alkyl (meth)acrylate having a C.sub.1 to C.sub.17 alkyl group and (a2) an alkyl (meth)acrylate having an alkyl group having 18 or more carbon atoms. The adhesive film has a ratio (B/A) of 90 peel strength (B) after aging the adhesive film at 25 C. for 30 minutes and leaving the adhesive film at 90 C. for 40 seconds to 90 peel strength (A) after aging the adhesive film at 25 C. for 30 minutes of about 0.1 or less.
