摘要:
This invention relates to a process for the co-encapsulation of biocidally active ingredients in a clay mineral, the process comprising the step of bringing the clay mineral into contact with a biocidally active nitrogen compound that contains at least one hydrocarbon group with 6 to 20 carbon atoms, and at the same time or subsequently with at least one biocidally active compound selected from the group consisting of 2-n-octyl-4-isothiazoline-3-one, 3-iodopropenylbutyl-carbamate and tetrahis(hydroxymethyl)phosphonium sulfate. And the use of such encapsulated product in water based paints, coatings and varnishes.
