The present invention relates to a moisture curable hotmelt adhesive composition comprising at least one polyurethane prepolymer obtained from the reaction of a) at least one polyether; b) at least one (meth)acrylic resin; c) at least one crystalline polyester; d) at least one amorphous polyester; e) at least one isocyanate compound; in a presence of a catalyst, wherein at least one of said polyether, crystalline polyester and amorphous polyester is partially or completely bio-based material.

A protective textile sleeve for providing protection to an elongate member contained therein; a method of construction thereof, and a method of bonding at least a portion of the sleeve to at least one of itself and an elongate member extending through a cavity thereof is provided. The sleeve has a wall of interlaced yarn, with the wall having an outermost surface and an innermost surface. The innermost surface is configured to bound a cavity extending between opposite open ends. The sleeve further includes an adhesive coating bonded to at least a portion of at least one of the outermost and innermost surfaces. The adhesive coating has a first, dried non-adhesive state and a second, wetted adhesive state, wherein the second adhesive state is activated via application of a water-based liquid thereto.

The present invention provides a joining structure with a joining strength higher than that of a conventional rubber core cord joining structure of a rubber ring. The invention also provides a solidifying agent for joining a rubber core cord that provides such a joining structure. A joining structure 2 of a rubber core cord 11 according to the present invention is a rubber core cord joining structure of which opposite end portions of the rubber core cord 11 or end portions of two rubber core cords are joined to each other with an adhesive. A solidified portion 23 formed by a solidifying agent 25 that has solidified is formed at each of the opposite end portions of the rubber core cord 11 or each of the end portions of the two rubber core cords, and the solidified portion 23 contains porous particles. The solidifying agent 25 according to the present invention is a solidifying agent that is applied to the rubber core cord 11, and contains a solvent containing a solidification component and porous particles contained in the solvent.

A method of applying a linerless label to an article wherein a web of joined labels is die cut from a web of label material in which the adhesive is protected by a water-soluble coating which provides a cushion between an anvil and die cutting means. The water-soluble coating is at least partially removed by exposure to water in a press following die-cutting, in a label applicator, or in an off-line unit. The web of joined labels may be wound and unwound between each of the above options. The web of joined labels may be separated in a label applicator by breaking a weakened boundary between adjoining labels or by cutting at a boundary between the label and the adjoining label. The linerless label may contain anti-counterfeit means that may be subsequently identified overtly and/or covertly.

An autohesive polymer material that includes: at least one polymer having at least two terminal silyl groups of the Formula (1) given by:

Si(R.sup.1).sub.a(R.sup.2).sub.b(1).

Each of the radicals R.sup.1 comprises an alkyl, alkenyl or aryl group or a hydrogen atom. Each of the radicals R.sup.2 comprises a group that can be eliminated with water, b is 1, 2 or 3, and a is 3b. The polymer material further includes at least one condensation catalyst. Further, the polymer material is chemically precrosslinked and further crosslinkable with moisture. In addition, the polymer material is configured for use as a layer body that can be applied to a substrate. The polymer material of this kind can also be used for producing permanent bonds.

Provided herein is a water-activated adhesive comprising an aqueous emulsion of vinyl acetate, polyvinyl alcohol, and glycerin. The adhesive has no significant tack prior to being activated, can be repositionable for at least 1 minute after activation, and can form a strong bond less than two hours after activation. Also provided are labels comprising the water-activated adhesive, methods for producing and using the water-activated adhesive, and systems for labeling articles with the water-activated adhesive.

A method of configuring tape for securement to a substrate. The tape has a face ply comprising an upper side and a lower side. The method comprises formulating a liner coating by: (a) creating a mixture comprising a non-toxic remoistenable adhesive and activated coconut carbon filtered water; and (b) adding gypsum to the mixture. The method comprises situating an adhesive on the lower side and covering the hot-melt adhesive on the lower side with the liner coating. The method includes using moisture to dispel the liner coating before the tape is applied to the substrate.

Provided are an adhesive composition which can give high adhesive force to a wet surface and also ensures storage stability of a moisture-curable component, an adhesive layer made from the adhesive composition, and an adhesive sheet including the adhesive layer. An adhesive composition including a base polymer and a moisture-curable component, wherein the base polymer contains a polymer having a functional group that becomes a functional group capable of reacting with the moisture-curable component through a reaction with water, and the moisture-curable component is contained in an unreacted state.

Described is an adhesive coating that can be applied, for example, to a surface of the insulation product. The adhesive coating includes between about 15-40% by weight of the adhesive coating of at least one of polystyrene-maleic anhydride (SMA) and polyacrylic acid (PAA), between about 15 and 50% by weight of the adhesive coating of a polyvinyl alcohol, between about 0.05% and 1.0% by weight of a homogenizer, and between about 20 and 40% by weight of the adhesive coating of a starch paste. The adhesive is activated with the application of liquid water.
