The invention relates to an aqueous polymer dispersion comprising: a) an aqueous polymer dispersion comprising grafted rubber polymeric particles from rubber polymer being selected from natural or synthetic rubber, b) an aqueous polymer dispersion with polymeric particles of a second polymer comprising monomeric units derived front a monomeric composition b) comprising: b1) a (meth)acrylate of a linear or branched alcohol in C.sub.4 to C.sub.10 or a mixture of such (meth)acrylates, said (meth)acrylate having Tg.sub.b1 lower than −30° C., b2) optionally, at least one comonomer having Tg.sub.b2 higher than −30° C.,
with said grafted rubber polymeric particles being grafted in an aqueous dispersion by a part of said monomeric composition b) as defined above. The invention covers a process of preparation of said dispersion, an adhesive composition comprising said dispersion, the use of said dispersion in pressure sensitive adhesives, and the resulting adhesive.

Vibration damping viscoelastic damping material laminates are described. The tapes generally include at least two viscoelastic damping material layers and at least one substrate. The tapes may optionally include one or more release liners. Also described are constrained layer systems formed by adhering the tape to a first substrate and/or second substrate undergoing vibration.

The present invention relates to an inflation film and a method for manufacturing the inflation film, wherein the inflation film includes a base film, including: a polyamide-based resin; a copolymer containing polyamide-based segments and poly-ether-based segments; and an olefin-based polymer compound, and has a small variation in physical properties between a machine direction (MD) and a transverse direction (TD) of the film.

A method for manufacturing an optical connecting component includes the steps of inserting an optical fiber into one through hole of a plurality of through holes of a connector, rotating the optical fiber around an axis of the optical fiber in the one through hole and aligning and holding the optical fiber at a predetermined position, blocking the end part of a through hole adjacent to the one through hole into which the optical fiber is inserted with a jig on an end face of the connector provided with the plurality of through holes, and fixing the optical fiber to the connector in a state in which the end part of the adjacent through hole is blocked.

An adhesive composition may be applied to a surface, such as plastic, metal, wood, stucco, plaster, brick, concrete, glass, rubber, tile, fiberglass, ceramic, porcelain, canvas, stone, or drywall. The adhesive-containing surface is then pressed into contact with a second surface to create a strong, watertight bond. The methods disclosed herein may be used to assemble and/or repair a variety of articles and structures, such as roofs, gutters, boats, kayaks, personal watercraft, canoes, rafts, inflatable articles such as toys, sporting equipment, and air mattresses, outdoor equipment, mobile homes, recreational vehicles, campers, garden hoses, low-pressure PVC and plumbing pipes, tents, vinyl awnings, covers and tarps, swimming pools, windows, doors, walls, seams, vents, air ducts, HVAC systems, and the like. Also disclosed herein are methods of testing the bonding strength of an adhesive, methods of affecting underwater repairs, and methods of assembling an all-terrain vehicle.

An adhesive compositions containing at least one first styrene-isoprene-styrene block copolymer having a diblock content of not less than 45%, at least one second styrene-isoprene-styrene block copolymer having a styrene content of not more than 30 wt.-%, at least one first tackifying resin having a softening point of equal to or higher than 100° C., and at least one second tackifying resin having a softening point of equal to or higher than 120° C. Further, a method for bonding substrates together using the adhesive composition.

Adhesion-promoting compositions containing organic titanates and/or organic zirconates and the use of the adhesion-promoting compositions to provide adhesion-promoting layers to enhance adhesion between metal substrates and an overlying free radical-polymerized sealant are disclosed.

A gap finishing tape for use with drywall applications includes a trim strip body extending along a central body axis, a hot melt adhesive extending along the central body axis, and a backing paper. The trim strip body includes a first surface, a second surface opposite the first surface, a first side, and a second side opposite the first side, and is at least partially constructed from a metallic material. The backing paper is at least partially secured to the second surface of the trim strip body. The trim strip body is at least partially embedded in the hot melt adhesive.

Provided are adhesive compositions that include an acrylate component and a charcoal component. The adhesive compositions are useful for adhering articles, for example, lashes or lash extensions to surfaces such as skin.

A silicone-based adhesive protective film and an optical member including the same are provided. A silicone-based adhesive protective film is formed of a composition including a silicone resin, a crosslinking agent, and a curing catalyst, and the silicone-based adhesive protective film has a peel strength of about 3 gf/inch or less with respect to a glass plate at 25 C., and a modulus of about 0.5 MPa to about 7 MPa at 25 C.
