Provided herein is a composition for use as a thermal interface material in a heat-generating device. The composition comprises a first part and a second part, the first part comprising polyisobutylene, a reactive diluent mixture, a catalyst, and one or more thermally conductive fillers, and the second part comprising polyisobutylene, the reactive diluent mixture, a silicone based cross-linker, an inhibitor and one or more thermally conductive fillers.

Thermal interface material

Provided herein are stretchable conductive inks consisting of a continuous polymer phase with dispersed silver flakes and a low melting metal or alloy, wherein initial resistivity is measured before elongation and the resistivity of the stretchable conductive ink composition is less than 10 times the initial resistivity at 50% elongation.

Stretchable electrically conductive ink compositions

Disclosed herein are stretchable conductive ink compositions comprising a polymer, conductive flake, an additive, and optionally conductive beads, wherein the initial resistivity is measured before elongation, and wherein the resistivity at 50% elongation is about 10 times or less of the initial resistivity.

The present invention provides fast fixturing two part adhesive compositions which include a first part containing a (meth)acrylic component and a cure system for an epoxy resin component of the second part and a second part containing an epoxy resin component and a cure accelerator for the (meth)acrylic component of the first part.

Adhesive compositions

Two part curable compositions are provided, which include a cure accelerator defined with reference to compounds shown in structure I where A is CHor benzyl, R is Calkyl, R' is H or Calkyl, or R and R&#x2032; taken together may form a four to seven membered ring fused to the benzene ring, R&#x2033; is optional, but when R&#x2033; is present, R&#x2033; is halogen, alkyl, alkenyl, cycloalkyl, hydroxyalkyl, hydroxyalkenyl, alkoxy, amino, alkylene- or alkenylene-ether, alkylene (meth)acrylate, carbonyl, carboxyl, nitroso, sulfonate, hydroxyl or haloalkyl, and EWG is as shown, an electron withdrawing group, such as nitro, nitrile, carboxylate or trihaloalkyl.

Two part curable composition

Benzoylthiourea or benzoylthiourethane derivatives as cure accelerators for two part curable compositions are provided.

Accelerators for two part curable compositions

Benzoylthiourea or benzoylthiourethane derivatives as cure accelerators in primers for two step adhesive systems are provided.

Accelerators for two step adhesive systems

Benzoylthiourea or benzoylthiourethane derivatives as cure accelerators for curable compositions are provided.

Accelerators for curable compositions

Benzoylthiourea or benzoylthiourethane derivatives, together with oxidants and a source of protons, acting as cure accelerators for two part curable compositions are provided.
