The disclosed thermally bondable adhesive tape backing has a pressure-sensitive adhesive at a surface and a thermoplastic polyurethane adhesive at an opposite surface for thermal bonding to a device. The thermoplastic polyurethane adhesive softens and melts at a relatively low temperature. Therefore, melting of thermoplastic polyurethane adhesive is achieved while the pressure-sensitive adhesive remains in place and is not pressed away at the region of the thermal bonding.

A multilayer film and a decorative film, each of which is excellent in chipping resistance, exhibits favorable adhesive properties to a variety of resin materials, such as polypropylene and ABS, and a molded body provided with such a film. The multilayer film includes three layers of an impact absorption layer (a), a base material layer (b), and a pressure sensitive adhesive layer (c) disposed in this order, wherein a thermoplastic polymer composition constituting the impact absorption layer (a) is composed of at least one block copolymer containing a polymer block (X) containing a structural unit derived from an aromatic vinyl compound and a polymer block (Y) containing a structural unit derived from a conjugated diene compound, or a hydrogenated product thereof; and has a loss tangent (tan δ) at 11 Hz in a range of −50 to −20° C. of 3×10.sup.−2 or more.

The present disclosure is directed to a formulations of cements and methods for bonding dissimilar materials. The formulations and methods can bond a Non-polyvinyl chloride (PVC) containing first polyolefin that is amorphous or has low crystallinity to a second material that is a rigid material or a hard PVC. The methods and formulations can work by co-dissolution at an interface, or activation of a one of the materials prior to bonding.

A roll and a method for producing a roll which are capable of effectively preventing tunneling are provided. A roll includes a core having a tubular shape and a laminate wound around the core. The laminate includes a process film, a surface coat layer, a substrate layer, an adhesive layer, and a release liner, in this order, in a laminating direction. The process film is formed from at least one member selected from polyethylene terephthalate (PET), polyolefins, and polyvinyl chloride (PVC). The surface coat layer is formed from a fluorine resin. The release liner is formed from polyethylene terephthalate (PET). The core is formed from an acrylonitrile-butadiene-styrene copolymer resin (ABS) or polypropylene (PP).

The composition includes an acrylic monomer having a carboxylic acid group, an acrylic monomer having a hydroxyl group, at least one of an alkyl acrylate or alkyl methacrylate, and from 20 to 35 percent by weight of a compound composed of divalent segments L and at least two X groups. The divalent segments L are represented by formula L. Each segment L is respectively directly bonded to two secondary N atoms, two tertiary N atoms, or a secondary and a tertiary N atom. Each R.sup.1 represents an alkylene group having from 1 to 4 carbon atoms, and at least some of the R.sup.1 groups are CH.sub.2CH.sub.2CH.sub.2CH.sub.2. Each X group is independently represented by the formula CH.sub.2C(R)C(O)OVWC(O).

The present disclosure relates to a two-component polyurethane adhesive, based on a polyol component A and a polyisocyanate component B. The two-component polyurethane adhesive exhibits fast cure speed, good adhesion properties and good durability. The two-component polyurethane adhesive is developed for the adhesion adhesion of substrates, wherein the substrates are preferably selected from the group comprising sheet molding compounds (SMCs) and plastic substrates.

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 provides a vacuum thermoforming adhesive composition containing a polyurethane polymer and an acrylic polymer and having a difference in melting temperature and cross-linking temperature of 30-60 C. In addition, provided is a vacuum thermoforming decoration sheet comprising: an adhesive layer, a substrate layer formed on the adhesive layer; a printing layer formed on the substrate layer, and a transparent substrate layer formed on the printing layer, wherein the adhesive layer is formed from the defroster vacuum thermoforming adhesive composition.

The present disclosure provides adhesive mounting articles that can be removed from surfaces without damage by having reduced contribution of a hardgood to the peel force generated by the adhesive article during removal. In some instances, this can be accomplished by a hardgood that is flexible in a peel direction and rigid in a weight hanging direction. Such hardgoods may include a plurality of minimally connected body segments arranged about the transverse axis of the hardgood body.
