摘要：
process for coencapsulation of biocidically active compounds in clay minerals functionalized by nitrogen compounds. This invention relates to a process for co-encapsulating biocidically active ingredients in a clay mineral, the process comprising the step of bringing the clay mineral into contact with a biocidically active nitrogen compound that contains at least one hydrocarbon group having a 6-membered hydrocarbon group. at 20 carbons, and at the same time or subsequently with at least one biocidically active compound selected from the group consisting of 2-n-octyl-4isothiazoline-3-one, 3-iodopropenylbutyl carbamate and retracis (hydroxymethyl) phosphonium sulfate . and the use of such an encapsulated product in water-based paints, coatings and varnishes.processo para coencapsulamento de composto biocidicamente ativos em minerais de argila funcionalizados por compostos de nitrogênio. esta invenção refere-se a um processo para o coencapsulamento de ingredientes biocidicamente ativos em um mineral de argila, o processo compreendendo a etapa de colocar o mineral de argila em contato com um composto de nitrogênio biocidicamente ativo que contém pelo menos um grupo hidrocarboneto com 6 a 20 carbonos átomos, e ao mesmo tempo ou subsequentemente com pelo menos um composto biocidicamente ativo selecionado a partir do grupo consistindo em 2-n-octil-4isotiazolina-3-ona, carbamato de 3-iodopropenilbutila e sulfato de retracis (hidroximetil) fosfõnio. e o uso de tal produto encapsulado em tintas, revestimentos e vernizes à base de água.
