An object of the present invention is to provide a hot melt adhesive being environmentally-friendly, having excellent adhesion property to various substrates such as paper substrate and polyolefin substrate, as well having excellent thermal stability. The present invention relates to a hot melt adhesive comprising: (A) a polar functional group-modified polymer, (B) an aliphatic polyester-based resin, (C) an olefin-based polymer, and (D) a tackifier resin.

The present invention provides hot melt adhesives for disposable products. The hot melt adhesives may be applied at high-speed and at low temperature ranges. The hot melt adhesives also provide excellent adhesion to polyethylene and a nonwoven fabric. The hot melt adhesive comprises (A) a thermoplastic block copolymer, which is a copolymer of a vinyl-based aromatic hydrocarbon with a conjugated diene compound; and (B) a propylene homopolymer having a melting point of 100° C. or lower, which is obtainable by polymerizing propylene using a metallocene catalyst. The disposable products are produced at high-speeds and low temperature with the inventive hot melt, and therefore, the disposal products are produced efficiently and safely, and a nonwoven fabric and a polyethylene film of the disposable products are less likely to peel.

A cellulosic fiber-based adhesive tape substrate, at least one side of which is coated with an aqueous mixture of: a) at least one organic polymer having pendant groups with at least one vinyl function; b) at least one polysiloxane comprising at least one hydrogenosiloxane monomer —(O—SiR.sup.1H)—, wherein R.sup.1 is a linear or branched and/or cyclic hydrocarbon chain which may contain heteroatoms; c) at least one hydrosilylation catalyst.

A cellulose fiber-based substrate, at least one side of which is coated with an aqueous mixture composed of: a) at least one water-soluble polymer (WSP) containing hydroxyl groups, b) at least one lactone substituted with at least one linear or branched and/or cyclic C.sub.8-C.sub.30 hydrocarbon chain which may contain heteroatoms, c)at least one crosslinking agent. A method of production and use thereof.

The invention is directed to a joint tape for finishing a joint between boards comprising a nonwoven substrate that does not swell substantially in the presence of water. The invention further provides a method of finishing a joint between boards comprising (i) applying a joint tape of the invention to a joint between boards by embedding the joint tape in a first coat of joint compound, (ii) applying a second coat of joint compound over the tape, wherein step (ii) is carried out before the joint tape and joint compound applied in step (i) have substantially dried, and optionally (iii) applying a third fill or finish coat of joint compound over the tape, wherein step (iii) is carried out before the joint tape and second coat have substantially dried.

An adhesive tape (1), including a substrate (6) including a stitched fleece (2) and an adhesive layer (7) applied on one side to the substrate (6), wherein the stitched fleece (2) is formed at least 80% of long fibers (3) that have a fiber length (L.sub.1) of 80 mm to 120 mm. The adhesive tape having improved abrasion properties while maintaining a high noise damping.

A pressure-sensitive adhesive is provided including an emulsion polymer containing a (meth)acrylate copolymer and nanocrystalline cellulose. The inclusion of the nanocrystalline cellulose results in an increase in the overlap shear properties of the adhesive while maintaining the peel adhesion. Articles and emulsions including the pressure-sensitive adhesive are also provided.

Articles and methods of making articles are described. In one embodiment, an electrode is described, comprising an ionically-conductive hydrogel layer comprising a first major surface and opposing major surface. The electrode further comprises a discontinuous primer layer disposed on the first major surface ionically-conducting hydrogel layer and an electrically conductive member or a connector component thereof, in contact with the first major surface of the ionically-conducting hydrogel layer. In another embodiment, an article is described comprising a hydrogel layer comprising a first major surface and opposing major surface; a discontinuous hydrophobic primer layer disposed on the first hydrogel layer; and a hydrophobic adhesive or hydrophobic backing bonded to the primer and discontinuous hydrophobic primer layer of the hydrogel.

Various carton sealing tapes are disclosed that have a plurality of security features, at least two of which include nanomarker particles having identification indicia visible under about 100 to about 400 times magnification and taggants visible upon exposure to a pre-selected wavelength outside the visible spectrum included in the same or different layers of the tape structure depending upon the selection of the backing material for the substrate of the tape. The carton sealing tapes are also printable for inclusion of a consecutive sequence of coded identification information in the form of a barcode or a 2D code.

A multilayer tape assembly is described which can be used with insulation jacketing and particularly for self sealing lap (SSL) applications. The tape assembly includes two adhesive layers with associated carrier and release layers in conjunction with a differential release system. Various methods of use are also described.
