  • Use of microcapsules for making paints and lacquers
    Patent number: 8758790
    Abstract: The invention provides microcapsules having an average diameter of 0.1 to 25 ?m, obtained by a process (a) or (b), wherein, (a1) preparing an aqueous emulsion comprising actives and optionally oil components and/or emulsifiers; (a2) treating the emulsifier with an aqueous solution of anionic polymers to form a matrix; (a3) contacting the matrix with an aqueous solution of cationic polymers to form a capsule and optionally (a4) separating the aqueous phase from the capsules, or (b1) preparing an aqueous emulsion containing actives and optionally oil components and/or emulsifiers; (b2) treating the aqueous emulsion with an aqueous solution of cationic polymers to form a matrix; (b3) contacting the matrix with an aqueous solution of an anionic polymer to form a capsule and optionally (b4) separating the aqueous phase from the capsule. The microcapsules are useful in paint and lacquer formulations.

  • Process for obtaining aqueous compositions comprising curing epoxy agents
    Patent number: 7781499
    Abstract: A process for obtaining aqueous compositions including curing epoxy agents includes providing an aqueous mixture comprising at least one polymercaptan, at least one di- or poly(amido)amine, and water, and reacting the aqueous mixture with an uncured epoxy resin to form a final cured epoxy resin is provided. A process for obtaining aqueous compositions including curing epoxy agents includes providing an aqueous mixture of at least one waterpoxy treated with at least one polymercaptan, and reacting the aqueous mixture with an uncured epoxy resin to form the final cured epoxy resin is also provided.
