ONE-COMPONENT THERMOSETTING EPOXY COMPOSITION WITH IMPROVED ADHESION
A one-component thermosetting epoxy resin composition includes at least one epoxy resin A having on average more than one epoxide group per molecule, at least one latent hardener B for epoxy resins, at least one impact modifier D, at least one physical or chemical blowing agent E and fibrous anhydrous magnesium oxysulfate MOS. Thermally expandable epoxy resin compositions have improved adhesion, especially on metal substrates.

Non-linear surfactant
A non-linear surfactant, and particularly a non-linear surfactant comprising bi-functionalized molecules or particles having both hydrophobic and hydrophilic groups. The non-linear surfactant includes a nanoparticle template of a rigid molecular structure, wherein the nanoparticle comprises a molecule or a particle that is bi-functionalized with both hydrophilic and hydrophobic groups to obtain an amphiphilic nanoparticle. The template nanoparticle can be used as a surfactant, wetting agent, emulsifier, detergent or other surface active agents or for the preparation of nanoemulsions or dispersions. The non-linear surfactant can provide smaller particle sizes for emulsion suspensions and foams.

THERMALLY CONDUCTIVE LIQUID COMPOSITION
Provided is a thermally conductive liquid composition containing a matrix resin (A) and thermally conductive inorganic particles (B). The matrix resin (A) accounts for 2 mass % or more and 8 mass % or less and the thermally conductive inorganic particles (B) account for 92 mass % or more and 98 mass % or less relative to 100 mass % of the thermally conductive liquid composition. The thermally conductive inorganic particles (B) include thermally conductive inorganic particles (B1) of 100 μm or more and 500 μm or less and thermally conductive inorganic particles (B2) of 0.01 μm or more and less than 100 μm. In the volume-based cumulative distribution curve, the thermally conductive inorganic particles (B1) account for 25 vol % or more and 50 vol % or less and the thermally conductive inorganic particles (B2) account for 50 vol % or more and 75 vol % or less relative to 100 vol % of the thermally conductive inorganic particles (B). Thus, the thermally conductive liquid composition has improved fluidity and is smoothly extruded from a discharge orifice of a small diameter while having high thermal conductivity.
