Digunakan untuk menyemprotkan tabung Chromoly untuk lebih tahan 3x dibandingkan coating asli. Dapat digunakan juga aplikasi lain yang disemprotkan pada besi/bahan metal lain-nya tanpa mengakibatkan perubahan struktur material asli yang disemprotkan. • Protect steel cylinders and other steel products from rust • THE original cold galvanizing compound with fifty years of proven success • True galvanic protection. Equivalent to hot-dip galvanizing • Color: matte gray. Single-component – Battleship gray finish • Apply by brush, roller or spray • Meets VOC standards in all 50 states • Available in clog-free aerosol form • Cold galvanizing zinc compound • 12 ounce aerosol can GENERAL PROPERTIES: ZRC® is a high-quality cold galvanizing compound based on a trade secret organic binder which affords true galvanic anti-corrosion protection to metals. The dried film of ZRC is 95% 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 is widely 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 alkalis TEMPERATURE RESISTANCE (non-immersion): Continuous: 350°F max/177°C max Non-Continuous: 750°F max/399°C max SALT FOG EXPOSURE: 2,852 Hours (ASTM B117) PROHESION/QUV EXPOSURE: 2,000 Hours (ASTM D5894) VOC: 3.3 Lbs/gal (385 gms/Ltr) (ASTM D3960) SOLIDS CONTENT: % Solids of Liquid Coating — 86% (by weight)/52% (by volume) METALLIC ZINC CONTENT: 95% by weight in dry film.
