Extender from Evonik
Structurally modified, hydrophilic AEROSIL® improves the antifouling properties and product life of antifouling coatings. It is used in formulations with cuprous oxide (Cu2O) to take advantage of the resulting synergies. VP 4200 is a development product that, as an active extender with cuprous oxide, exhibits effective antifouling properties while lowering the amount of Cu2O needed in the coating formulation.
