Abstract:

Ten zinc inorganic silicate coatings were exposed for 5 years at the three atmospheric environmental test sites of the Naval Civil Engineering Laboratory. These test sites are Kwajalein, Marshall Islands Kaneohe, Hawaii both tropical environments and Port Hueneme, California. The zinc inorganic silicate coatings were exposed with and without topcoats. It was found, that in general, postcuring and superior self-curing zinc inorganic silicate coatings without topcoats will give long-term protection to steel. A compatible topcoat will improve the protective properties, especially of an inferior zinc inorganic silicate coating. Compatible vinyl, epoxy, or alkyd coatings are effective topcoats for the zinc inorganic silicate coatings.
