Part of the Interzinc 22 Series of products. A two component, rapid recoat, fast curing solvent based inorganic zinc rich ethyl silicate primer, containing 85% zinc by weight in the dry film. Conforms to SSPC Paint 20 Level 1. Available in ASTM D520, Type II (low lead) zinc dust version as standard PRODUCT DESCRIPTION A zinc rich primer suitable for use with a wide range of high performance systems and topcoats in both maintenance and new construction of bridges, tanks, pipework, offshore structures and structural steelwork. Interzinc 22 can also be used as tank coating suitable for the carriage of different chemical cargoes (e.g. styrene) according to International Paint’s chemical resistance guide. Provides excellent corrosion protection for correctly prepared steel substrates, up to temperatures of 1004°F (540°C) when suitably topcoated. Fast curing primer capable of application in a wide range of climatic conditions.
