Abstract

An anticorrosion material comprising colloidal particles and multivalent metal ions is disclosed. The particles are preferably silica. The metal ions may be Al, Ga, Ti, Zr, Hf, Zn, Mg, Ca, Nb, Ta, Fe, Cu, Sn, Co, W or Ce. The material can be added to a conversion coating liquid, mixed with a polymeric binder or used as such to form a coating.
