Specifications
TYPE: Single pack, premixed, ready-to-apply liquid organic zinc compound
GENERAL PROPERTIES: ZRC-221 is a advanced-technology cold galvanizing compound based on a trade secret organic binder which affords true galvanic anti-corrosion protection to metals. The dried film of ZRC-221 is 92% metallic zinc. Because of the uniqueness of the formulation, ZRC is the only coating of its type to be recognized under the Component Program of Underwriter's Laboratories, Inc.
RECOMMENDED USES: ZRC-221may be used without topcoat in place of hot-dip galvanizing. Also used as a high-performance base coat with a variety of topcoats. Used for repair of damaged hot-dip galvanizing, Galvalume® and zinc metallizing, regalvanizing worn hot-dip galvanizing, repair of weldments, and repair of damaged inorganic zinc coatings. Excellent for long-term protection of structural steel, water and waste facilities, power plants, transmission towers and antennae, steel decking and bridges, and numerous OEM uses.
SUBSTRATES: Apply to properly prepared carbon steel, cast iron, hot-dip galvanized, and aluminum surfaces.
