Micro-encapsulation of hydrophilic or water-sensitive solid particles, e.g. catalysts or other modifiers for use in paint, involves forming the capsule wall from amino resin precondensate in an aqueous-organic solvent mixture

摘要

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. 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.
