Abstract: Pressure-sensitive adhesive compositions and articles that include a layer of the pressure-sensitive adhesive compositions are provided. The pressure-sensitive adhesive compositions are particularly well suited for use with substrates that have been considered to have difficult to bond to surfaces such as those routinely encountered in the automotive industry. For example, the pressure-sensitive adhesive can be adhered to clear coat compositions, painted surfaces, and various polymeric materials having low energy surfaces (e.g., surfaces having a surface energy no greater than 35 dynes per centimeter).

Abstract: Thermally de-bondable adhesives are formed from curable compositions that have a two-stage curing mechanism. The first stage of curing forms a pressure sensitive adhesive and the second stage of curing, reduces the adhesion of the adhesive. The curable composition includes a curable composition and a thermally de-bonding composition. The curable composition includes a first alkyl (meth)acrylate monomer with 4-12 carbon atoms, a second hydroxyl-functional (meth)acrylate monomer, a crosslinker, and an initiator. The thermally de-bonding composition includes a blocked multi-functional isocyanate, and a metal salt catalyst. The Peel Adhesion of the cured adhesive upon heating to at least 180° C. for 1 hour is reduced by at least 15%.

Abstract: The present invention relates to a pressure-sensitive adhesive composition comprising an acrylate copolymer having a side carboxyl that is formed by a first monomer mixture containing a carboxyl-containing monomer, wherein, the content of the carboxyl-containing monomer is 0.1-10 wt. % based on the total weight of the first monomer mixture for forming the acrylate copolymer having the side carboxyl, the glass transition temperature Tg of the acrylate copolymer having the side carboxyl is larger than or equal to −55° C. and less than or equal to −30° C. The pressure-sensitive adhesive composition further comprises 1-25 wt. % of an acrylate oligomer with a weight-average molecular weight greater than or equal to 20,000 Da and a glass transition temperature Tg greater than or equal to 25° C., and 1-20 wt. % of a terpene tackifying resin based on the total weight of the acrylate copolymer having the side carboxyl and the acrylate oligomer. The pressure-sensitive adhesive composition also has a high peel force at room temperature and a high cohesive force at high temperature and has excellent anti-warping and anti-bubbling properties
