COATING ADHESION: INSURE COATING RELIABILITY
60 mil Coating Thickness Sprayed at 45o spray angle
designed to simulate worst case field spray conditions
Denotes Coating Adhesion
Exceeds Glue Strength
Nicko-Shield 200 has the unsurpassed adhesion strength typically exceeding glue
adhesion strength (>10,000 psi) per ASTM C633
HVAS = High Velocity Air Spray, PC = Powder Combustion

CORROSION RESISTANCE
Accelerated Corrosion
Possible Substrate Attack,
Enlarged Surface Area Exposure
Decelerated Corrosion
Coating Integrity Maintained
Against Attack
Nicko-Shield 200 demonstrates low, decelerating corrosion rate
attributed to self-sealing capability. ASTM G31 350oF H2SO4
