Abstract:
The present invention is an assembly layer for a flexible device. The assembly layer is derived from precursors that include about 0 to about 50 wt% C 1 -C 9 alkyl(meth)acrylate, about 40 to about 99 wt% C 10 -C 24 (meth)acrylate, about 0 to about 30 wt% hydroxyl (meth)acrylate, about 0 to about 10 wt% of a non-hydroxy functional polar monomer, and about 0 to about 5 wt% crosslinker.
Abstract:
Crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions, which include two (meth)acrylate copolymers plus a tackifier, are used to form the crosslinked compositions upon exposure to ultraviolet radiation. The crosslinked compositions can function as pressure-sensitive adhesives. The crosslinkable compositions are well suited for use with hot melt processing methods.
Abstract:
The present invention is directed to a multilayer pressure sensitive adhesive (PSA) film, having a first pressure sensitive adhesive layer and at least an opposing layer, wherein the first pressure sensitive adhesive layer comprises a pressure-sensitive adhesive composition with a (meth)acrylic-based elastomeric material comprising a reaction product of polymerizable material comprising: (a) a first monomer which is an alkyl (meth)acrylate ester of a primary alcohol R 1 -OH, the alkyl (meth)acrylate ester being of Formula (I) CH 2 =C(R 2 )-(CO)-OR 1 (I) wherein R 1 is an alkyl having 14 to 25 carbon atoms and the primary alcohol R 1 -OH has an iso index equal to at least 2 but no greater than 4; R 2 is hydrogen or methyl; and (b) a second monomer having an ethylenically unsaturated group; wherein the at least one opposing layer comprises at least one filler material. The invention is also directed to a method for the manufacturing of such a multilayer PSA film and its use.
Abstract:
Described herein is a paper-based backing and a tape that may be used in extreme high temperature applications. In one embodiment, the tape comprises (a) a backing comprising a paper and a saturant, wherein the saturant comprises a C2 to C6 (meth)acrylic ester; and (b) an adhesive disposed on the backing, wherein the adhesive comprises a crosslinkable (meth)acrylate polymer and a heat-activatable crosslinking agent, wherein the heat-activatable crosslinking agent is activated at a temperature of at least 80°C. In another embodiment, the backing comprises: (a) a paper and (b) a saturant, wherein the saturant comprises a butyl (meth)acrylic ester wherein the butyl (meth)acrylic ester permeates the paper and wherein the saturant is essentially free of a crosslinker, and the backing has an autoignition temperature of greater than 425°F (218°C).
Abstract:
The present disclosure provides an ionically crosslinkable composition comprising a (meth)acrylate copolymer component having pendant acid functional groups and pendant photobase functional groups. On exposure to light, the pendant photobase group photolyzes to provide a pendant amine group, that ionically crosslinks the copolymer.
Abstract:
This disclosure relates to viscoelastic damping materials and constructions which may demonstrate low temperature performance and adhesion and which may be used in making vibration damping composites. Viscoelastic damping materials and constructions may include polymers or copolymers of monomers according to formula I: CH 2 =CHR 1 -COOR 2 [I] wherein R 1 is H, CH 3 or CH 2 CH 3 and R 2 is a branched alkyl group containing 12 to 32 carbon atoms.
