Habicor® High performance corrosion inhibitors Corrosion

Metals tend to their most thermodynamically stable state (e.g. iron oxide). Corrosion is an electrochemically driven process where the metal degrades due to reaction with its environment.

Their Corrosion inhibitors protect your values activity varies depending on the selected coating system, the film thickness, the pigment loading and the substrate. Optimal performance depends on Anodic inhibitors selecting the ideal combination of pigments and Anodic inhibitors act by a reducing their concentration. anodic reaction.

Habicor® pastes Habicor® pastes are easy to use, pre-milled, binder- free pigment slurries. They can often be added to the formulation without additional grinding. Habicor® pastes reduce manufacturing costs and improve the flexibility of customers‘ production. These products do not form dust and therefore contribute to cleaner work places.
