TYPE:
Single pack, premixed, ready-to-apply, liquid organic zinc compoundGENERAL PROPERTIES: ZRC®221 is a high-quality metallic zinc coating 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®221 may 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.
NOT RECOMMENDED FOR: Contact with potable water, strong acids or strong alkalies
