Evonik introduces a new structure modified silica type from the AEROSIL® product group.
Germany, Essen. VP 4200 is a new structure modified silica type with free OH-groups that enables formulating more ecofriendly, cuprous oxide containing Anti-Fouling coatings.
It is tailor made for both CDP and SPC coatings. (CDP = Controlled Depletion Polymer; SPC = Self-Polishing Coating).
VP 4200 forms a complex with Cu2O and is thus better able to control the release of the biocide.
Formulations with only 10 pbw% cuprous oxide and 4 -6 pbw% VP 4200 leads to the same performance as the standard type with up to 50 pbw% Cu2O.
VP 4200 has a relatively low thickening effect, so higher amounts can easily be incorporated into the systems, especially in combination with TEGO® Dispers 1010.
VP 4200 belongs to Evonik’s product line of silica-based AEROSIL® types.
