Mikroverkapselungsverfahren und danach hergestellte mikroverkapselte partikulaere Feststoffe

DE1004004107 A UPAB: 20051104 NOVELTY - A method for the micro-encapsulation of hydrophilic and/or water-sensitive solid particles involves depositing a capsule wall on the particles (A) in a continuous phase comprising an aqueous-organic solvent mixture, starting from an amino resin precondensate (B) in the form of solid resin particles. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for micro-encapsulated solid particles with a hydrophilic and/or water-sensitive solid core and a capsule wall of hydrophobic amino resin. USE - For the production of initiators, catalysts, fire retardants, modifiers and/or crosslinkers, especially for use in paint or lacquer (claimed). ADVANTAGE - Enables the efficient micro-encapsulation of core materials which are partly water-soluble, water-swellable, ion-releasing and/or reactive towards water, or which undergo dissolution by salt formation during the encapsulation process, using an amino resin to form the capsule wall and without the formation of artefacts
