MICROENCAPSULAMENTO À presente invenção refere-se a um processo para produzir microcápsulas compreendo i) formar uma solução de um reticulante em líquido, ii) formar uma pasta fluida de um material inorgânico particulado modificado por superfície em meio aquoso; iii) dispersar a solução da etapai) na pasta fluida da etapaii) e fazer com que ou permitir ao reticulante reagir com o material inorgânico particulado modificado por superfície de maneira a formar uma parede de microcápsula reticulada A process for making microcapsules may include i) forming a solution of a cross-linker in a liquid; ii) forming a slurry of a surface-modified particulate inorganic material in an aqueous medium; and iii) dispersing the solution of step i) in the slurry of step ii) and causing or allowing the cross-linker to react with the surface-modified particulate inorganic material so as to form a cross-linked microcapsule wall.
