  • Epoxy resin compositions
    Patent number: 8779034
    Abstract: A low color epoxy resin composition comprising (a) an epoxy resin and (b) at least one an inorganic phosphorous-containing compound stabilizing agent, for example an additive such as sodium pyrophosphate dibasic (SPD) compound; wherein the resulting epoxy resin composition is storage stable and the epoxy resin composition exhibits a low color. The low color epoxy resin composition is used to prepare an epoxy encapsulant which is useful in light emitting diodes (LEDs).

  • Universal tint paste having high solids
    Patent number: 8753443
    Abstract: The invention relates to a high solids tint paste that is preferably substantially free of solvents that are volatile organic compounds. Preferably the universal tint paste is 100% solids and substantially free of any solvents. The universal tint paste is formed using a functional silicone resin intermediate that is end-capped with an alcohol, catalyzed to form a silicone resin product and combined with one or more desired pigments. The universal tint paste preferably can be used in a wide variety of solvent-borne and high solids coatings.
