摘要： Silicone-based pressure-sensitive adhesives, reaction mixtures used to form the pressure-sensitive adhesives, methods of making the silicone-based pressure-sensitive adhesives, and articles containing the silicone-based pressure-sensitive adhesives are described. More particularly, the silicone-based pressure-sensitive adhesives include silicone-based elastomeric materials that are prepared by polymerizing a silicone compound having at least two ethylenically unsaturated groups in the presence of actinic radiation (e.g., ultraviolet radiation) and a controlled radical initiator. The controlled radical initiator is a bis-dithiocarbamate or bis-dithiocarbonate compound having a single carbon between the two dithiocarbamate or dithiocarbonate groups.

摘要： Silicone polyoxamide and silicone polyoxamide-hydrazide copolymers comprise at least two repeating units of formula (I). In this formula, each R1 is independently an alkyl, haloalkyl, aralkyl, alkenyl, aryl, or aryl substituted with an alkyl, alkoxy, or halo; each Y is independently an alkylene, aralkylene, or a combination thereof; each G is independently a bond or a divalent residue equal to a diamine of formula R3HN—G—HR3 minus the two —NHR3 groups; each R3 is independently hydrogen or alkyl or R3 taken together with G and with the nitrogen to which they are both attached form a heterocyclic group; each n is independently an integer of 0 to 300; each p is independently an integer of 1 to 25, and the average of p is 1.3 or greater; and each q is independently an integer of 1 to 2, and the average of q is no greater than 1.05.

摘要： 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.

摘要： The present disclosure generally relates to adhesive compositions and articles including at least one of polydiorganosiloxane polyoxamide copolymer and/or silicone polyurea block copolymer and a silicate tackifying resin. Some embodiments of the adhesive composition include at least one of a polydiorganosiloxane polyoxamide copolymer and a silicate tackifying resin in an amount of between about 0.1 wt % and about 20 wt %; or a silicone polyurea block copolymer and a silicate tackifying resin in an amount of between about 0.1 wt % and about 30 wt %.

摘要： According to various embodiments of the present disclosure, a composition includes about 5 to about 40 parts by weight of a solute copolymer component. The solute component optionally has one Tg or Tm of at least 25° C. The composition further includes about 60 to about 95 parts by weight of a solvent monomer. The solvent monomer component includes (meth)acrylate monomers and a multifunctional acrylate. The sum of the solute copolymer component and the solvent monomer component is 100 parts by weight. The composition further includes about 5 to about 100 parts of a plasticizer, relative to the 100 parts. The plasticizer component comprises at least one plasticizer comprising an acid group.

摘要： 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.
