  1. NICKO-SHIELD 100 PRODUCT INFORMATION Justin Cheney, PhD CTO April 28, 2011

  2. PRODUCT OVERVIEW • NICKO-SHIELD 100: • Exceptional Coating Adhesion Insures Reliable Corrosion Protection and Resistance to Spalling, Coating Failure • Designed to Protect Refinery Vessels in Liquid Phase Condensing Acid Environments • Extremely Low Porosity for Extremely Low Permeability • Austenitic Nickel As-Sprayed Coating Matches Thermal Expansion Coefficient of Carbon Steels • Twin Wire Arc Spray Product Available in 0.045” and 1/16” diameter

  3. COATING ADHESION: INSURE COATING RELIABILITY Nicko-Shield 100 has the exceptional adhesion strength surpassing conventional and advanced corrosion resistant TWAS coatings per ASTM C633 HVAS = High Velocity Air Spray, PC = Powder Combustion

  4. CORROSION RESISTANCE Simulated Refinery Vessel Testing Nicko-Shield 100 coating surface after exposure Nicko-Shield 100 corrosion performance exceeds more costly High Velocity Air Fuel Alloy C276 Coatings per ASTM G31 2 wk. exposure to 96% H2SO4 at 350oF

  5. COATING INTEGRITY .03” .03” Nicko-Shield 100 Coating Alloy C276 100 Coating Nicko-Shield 100 has reduced porosity and oxide content providing an effective non-permeable barrier to corrosion

  6. TECHNICAL DATASHEET Applications: Refinery Vessels, (Condensing Acids, Weld Seam Protection) Adhesion: 10,000 psi (ASTM C633) Melting Temperature: 2150oF (1175 oC) Porosity: < 3% Oxide Content: <3% Corrosion Resistance: Excellent Similar or Superior to Alloy C276 Particle CTE: 13 x 10-6 Permeability: Very Low Chemical Composition: Ni Bal Si <5% B<5% Cr <35% Mo<20% Other<5% Recommended Parameters: TAFA 8830/8835 Atomizing Air Pressure: 50-75 psi Nozzle Cap: Green Nozzle Positioner: Long C Arc Load: 29-32 V Current: 175-250 A Coating Thickness Per Pass: 1.2-1.3 mil Coating Texture: < 300 μ-inch Spray Rate: 16 lbs/hr.
