Abstract: An isolator for protecting adjacently located dissimilar material substrates from galvanic corrosion. The isolator includes a backing layer having opposite major surfaces and a thickness, and an optional uncured adhesive layer having one major surface bonded to one of the major surfaces of the backing layer and another major exposed surface for being adhesively bondable to a surface of one of the dissimilar material substrates. In its cured state, the adhesive layer and the backing layer are each not permanently compressible. At least one or both of the cured adhesive layer and the backing layer is polar solvent resistant enough to prevent polar solvent transported metal ions from passing all the way through its thickness. In preferred embodiments the backing layer comprises a tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride (THV) material, and the adhesive layer comprises an epoxy resin.

Abstract: Core-sheath filaments are provided that comprise cores having diene-based rubbers that are crosslinked by multifunctional acrylates, resulting in superior high-temperature performance adhesives. The adhesive compositions have excellent durability against oxygen and moisture, low and stable dielectric properties, and superior high-temperature performance. Methods of making core-sheath filaments having cores including diene-based rubbers that are crosslinked by multifunctional acrylates and uses for such core-sheath filaments.

Abstract: Foam compositions are provided including a polylactic acid polymer; second (e.g., polyvinyl acetate) polymer having a glass transition temperature (Tg) of at least 25° C.; and plasticizer. Also described are articles comprising the foam compositions, such as a sheet or hearing protection article. Methods of making and using the foam compositions are further described herein.

Abstract: Provided is a composite film for attachment to an elastomeric substrate. The composite film comprises the following layers, in the order below: an elastomeric layer comprising a thermoplastic polyurethane; an ink layer; and a pressure sensitive adhesive layer comprising a styrenic block copolymer blended with a phenolic resin. Advantageously, the provided composite films can withstand harsh outdoor environments and stresses while providing high anchorage to elastomeric substrates, such as car tires, for a long service life.

Abstract: There is provided adhesive compositions comprising a styrenic block copolymer and at least one tackifier, where the at least one tackifier contains non-carbon hetero-atom functionality, and where the adhesive composition is wash durable when bonded to a substrate. There is also provided articles made using these adhesives.

Abstract: There is provided retroreflective articles comprising a binder layer comprising an adhesive composition comprising at least one tackifier and at least one elastomer selected from at least one of natural rubbers and synthetic rubbers, and a layer of optical elements at least partially embedded in a major surface of the binder layer. There are also provided articles of clothing using the presently disclosed retroreflective articles and methods for preparing the retroreflective articles.

Abstract: A pressure sensitive adhesive composition is described comprising a first block copolymer comprising polyvinyl aromatic end block and poly(vinyl aromatic/butadiene) copolymer block; at least 20 wt. % of a second polystyrene-polyisoprene-poly styrene block copolymer; and solid tackifying resin. The total amount of block copolymer typically ranges from 40-65 wt. % and plasticizing oil and liquid tackifying resin are present in a total amount of less than 20 wt.-% based on the total weight of organic components of the pressure sensitive adhesive composition. Also describe are adhesive articles and methods.

Abstract: An adhesive composition is described comprising a block copolymer comprising a polyvinyl aromatic block and a poly(vinyl aromatic/isoprene) copolymer block; and a tackifier. The block copolymer typically has the general structure: A?A/B or A?AB?B; wherein A is a polyvinyl aromatic block; B is a polyisoprene block; and A/B is a poly(vinyl aromatic/isoprene) copolymer block. Also described are adhesive articles, methods of bonding, and block copolymer blends.

Abstract: Foam compositions are provided including a polylactic acid polymer; second (e.g., polyvinyl acetate) polymer having a glass transition temperature (Tg) of at least 25° C.; and plasticizer. Also described are articles comprising the foam compositions, such as a sheet or hearing protection article. Methods of making and using the foam compositions are further described herein.

Abstract: The present disclosure generally relates to adhesive compositions, adhesive articles including the adhesive compositions, methods of making the adhesive compositions and articles, and methods of using the adhesive compositions and articles. The adhesive compositions of the present disclosure include a thermoplastic phenolic resin made from the reaction of (1) alkyl phenol (e.g., butyl- or octyl- or -nonyl) and formaldehyde; or (2) alkyl phenol (e.g., butyl- or octyl-) and acetaldehyde; or (3) alkyl phenol (e.g., butyl- or octyl-) and acetylene. The present disclosure also generally relates to adhesive articles including these adhesive compositions. The inventors of the present disclosure found that such adhesive articles exhibit excellent adhesion to architectural coatings with including low or no VOCs, deep base formulations, and/or formulations including primer in various conditions, including, for example, high humidity.
