  • Publication number: 20080292801
    Abstract: The present invention concerns adhesive compositions that provide corrosion-preventative properties and improved adhesive bonding on corrodible surfaces, such as may be found in electronic components. These compositions provide the substrates with greatly increased resistance to corrosion, especially during long term exposure to high temperatures and/or high humidity. When used on conductive substrates, the compositions also maintain good initial and ongoing electrical conductivity.

  • Patent number: 7422638
    Abstract: Sago-based gelling starches and the use thereof. Such modified starches exhibit exceptionally fast gelling properties, high gel strengths, and exceptional elasticity. These properties allow for significantly reduced processing times, including reduced hold times. Further, the higher gel strength allows for reduced starch levels without loss of final product gel strength integrity or texture. The instant gelling starches are particularly useful in food systems of the type that gel upon standing, such as pie and cream fillings, puddings, spreads, and jellies.

  • Publication number: 20080202380
    Abstract: A material for producing a conductive composition comprising polymer particles, conductive particles, and a liquid medium. The material is in a liquid/dispersion form until it is cured at which time it forms an electrically conductive composition. The composition contains larger sized polymer particles along with smaller metal conductive filler particles such as nanoparticle-sized filler particles. The larger polymer particles create excluded volume in the material matrix and reduce the percolation threshold of the conductive filler particles to provide a conductive material with a reduced volume fraction of electrically conductive filler. The electrical conductivity of the material is further increased after heat treatment which causes the conductive filler particles to sinter together to form a highly conductive network.
