  • Patent number: 6686008
    Abstract: The invention is a composition made by mixing a multifunctional acrylate with an aminofunctional silane and an ethylenically unsaturated acid to form a reaction product, optionally dissolved in a solvent, characterized in that the multifunctional acrylate has a molecular weight of from about 100 to about 3000. The composition can be coated on a substrate, then optionally exposed to moisture and treated to initiate a free radical reaction. The invention can be applied to a variety of substrates used in packaging applications. The reaction mixture can further be cured by heating in the presence of moisture. The free radical reaction can be initiated by electron beam irradiation, ultraviolet radiation, gamma radiation, and/or heat and chemical free radical initiators.

  • Patent number: 6300390
    Abstract: The present invention provides a resin-based dental restorative that exhibits low volumetric shrinkage, high filler loading and the high strength required for load bearing restorations, yet maintains a glossy appearance, even after substantial wear. To this end, a dispersant is mixed with a methacrylate resin and a structural filler having a mean particle size between about 0.05 &mgr;m and about 0.50 &mgr;m. The composite is useful in stress bearing restorations and in cosmetic restorations. The structural filler used is typically ground to a mean particle size of less than 0.5 &mgr;m and also includes a microfill having a mean particle size less than 0.05 &mgr;m to improve handling and mechanical characteristics. The preferred dental composites maintain their surface finish even after substantial use and also have the strength properties of hybrid composite resins.
