ABSTRACT:
A composition suitable for the preparation of a surface protective coating composition e.g. a paint by admixture with an organic film-forming binder comprises (i) elemental zinc in particulate form and (ii) inorganic oxide particles such as silica having corrosion inhibiting cations e.g. calcium chemically bound to the surface by ion exchange. The amount of elemental zinc to inorganic oxide is preferably from 75:1 to 3:1 by weight. The binder can be organic e.g. an epoxy resin, epoxy ester, chlorinated rubber or polystyrene or may be inorganic e.g. silicates.
