Methods of disassembling apparel products having shape memory adhesives
Embodiments provide methods of disassembling an apparel product. The methods include exposing an adhesive of the apparel product to heat or electromagnetic energy. The adhesive is disposed at least partially disposed between a major component and a minor component of the apparel product. The adhesive includes a shape memory material. The major component forms a base portion of the apparel product and is configured to be supported and worn at least partially over a portion of a wearer. The minor component forms a secondary portion configured to be coupled to the major component with the adhesive. The methods include separating the major component from the minor component adjoined by the adhesive.
PRESSURE-SENSITIVE ADHESIVE COMPOUNDS, AND SELF-ADHESIVE PRODUCTS AND COMPOSITES COMPRISING THE LATTER
The present invention relates to a foamed pressure-sensitive adhesive compound on the basis of aromatic polyvinyl-polydiene block copolymers, in particular for double-sided self-adhesive strips, containing a) 39.8 wt. % to 51.8 wt. % of an elastomer component, b) 35.0 wt. % to 58.0 wt % of an adhesive resin component, c) 2.0 wt. % to 15.0 wt. % of a plasticizer component, d) 0.0 wt. % to 18.0 wt. % of further additives and e) microballoons, the microballoons being at least partly expanded.
A FILM BACKING FOR RELEASABLE SECUREMENT
The disclosed film backing has a multilayer extensible substrate with a securing adhesive that can secure to a surface and a tab to stretch the extensible substrate to remove the securing adhesive from the underlying surface. Stretching the extensible substrate will easily release the adhesive from the underlying surface. Therefore, a strong adhesive can be used. The multilayer extensible substrate includes an elastic layer forming the core adjacent to a plastically-deforming layers forming the skin to minimize the elasticity of the overall construction.
FOAMED ADHESIVE MASS LAYER AND ADHESIVE TAPE COMPRISING THE FOAMED ADHESIVE MASS LAYER
The invention relates to a foamed adhesive mass layer comprising a) 41.7 to 62.0 wt. % of an elastomer component, b) 37.7 to 58.0 wt. % of an adhesive resin component, c) 0 to 15 wt. % of a soft resin component, d) 0 to 18 wt. % further additives, and e) microballoons with a proportion of preferably 0.3 to 2.5 wt. %, preferably 0.5 to 2.0 wt. % and particularly preferably 0.7 to 1.7 wt. %, wherein the microballoons are at least partially expanded, wherein the elastomer component (a) consists of up to at least 90 wt. % polyvinyl aromatic compound polydine block copolymer, wherein the adhesive resin component (b) contains up to 4 to 100 wt. % of at least one type K1 if a rosin oligomer with a softening temperature (Ring & Ball, Test VI) of at least 90° C., and wherein the density (Text IX) of the foamed adhesive mass layer is at least 600 kg/m.sup.3 and max. 920 kg/m.sup.3.
PRESSURE-SENSITIVE ADHESIVE TAPE
An adhesive tape with high repeelability from the state that a portion of the adhesive tape has already been peeled from an adherend is provided. The adhesive tape includes a substrate layer and an adhesive layer. The substrate layer has a breaking stress in a range of 1 to 90 MPa and an elongation at break in a range of 400% to 3000%. The adhesive tape satisfies the following relational expression (i): [Math. 1] P.sub.400/P.sub.0≤0.9 (i). P.sub.0 denotes an initial cleavage strength N/cm.sup.2 of the adhesive tape, and P.sub.400 denotes a cleavage strength N/cm.sup.2 when the adhesive tape is stretched by 400%.
Stretchable adhesive film and display device comprising same
The present disclosure relates to a stretchable adhesive film comprising a substrate layer comprising an elastomer; and a first adhesive layer provided on one surface of the substrate layer, wherein the stretchable adhesive film satisfies Equation 1, and a display device comprising the same.
REPOSITIONABLE ADHESIVE ARTICLES FOR STRETCH RELEASE REMOVAL
The present disclosure relates to adhesive article that include a first, stretch releasable adhesive and patterned adhesive elements on, within, or partially embedded in a surface of the adhesive. The adhesive elements can act as spacers between the adhesive surface and the mounting surface to prevent full contact and wet out of the first adhesive, whereby the article can be removed from the wall and placed at a new location without damage to the wall surface or the article. Once the final location is selected, the separation created by the engineered elements can be overcome by applying sufficient pressure; the first adhesive can contact and adhere more permanently to the wall. Thus, a stretch releasable adhesive articles of the present disclosure can move freely relative to the desired mounting surface, while developing additional tack and holding power after sufficient pressure is applied.
Stretch-Release Adhesive Articles with a Pattern of Slits
Stretch-release adhesive articles with tunable mechanical properties are provided. The articles include a stretchable carrier extending along a first direction and including a first major surface and a second major surface opposite the first major surface. At least one of the first and second major surfaces of the stretchable carrier is a stretch-releasable adhesive surface, and the stretchable carrier includes a pattern of slits distributed thereon and configured to deform upon a stretch on the stretchable carrier to elongate the stretchable carrier.
Conformable adhesive articles
The present disclosure generally relates to conformable adhesive articles that are capable of attaching or adhering to a substrate and that can be removed from the substrate without causing damage to the substrate. The present disclosure also generally relates to methods of making and using such adhesive articles. In some embodiments, the adhesive article includes (1) a releasable layer having a first major surface and a second major surface; the second major surfaces including a pressure sensitive adhesive capable of adhering the adhesive article to a surface; and (2) a compliant layer having a first major surface and a second major surface; the second major surface of the compliant layer adjacent to the first major surface of the releasable layer. In some embodiments, the releasable layer debonds from both the surface and the compliant layer when the adhesive article is stretch released at an angle of less than 35 degrees.
ADHESIVE TAPE WITH CROSSLINKED POLYURETHANE CARRIER
The present invention relates to a redetachable adhesive tape having a carrier based on a crosslinked polyurethane and an adhesive layer based on vinylaromatic block copolymer, to a method for producing the adhesive tape and the use of the adhesive tape in the production of electronic components.
