APPLICATION
Surface Preparation
Substrate should be free of grease, oil, dirt, fingerprints, drawing compounds, rust inhibitors, or any other surface con- tamination that could affect adhesion. For structural steel applications, Cortec® recommends a minimum of a NACE #3/ SSPC-SP6 commercial blast clean. Consult Cortec® and/or test system adhesion prior to full scale application.

Note: Make sure dew point is more than 5°F (2°C) less than air temperature for application. Power agitate to a uniform consistency using a “squirrel cage” type mixer, hand-held drill mixer, or other equivalent method. VpCI®-391 can be applied by spray, roll, brush, or dip.

Typical Equipment Setups
HVLP / Conventional Spray
•Tip .009”-.021” *dependent upon pressures and viscosity
•Air Pressure 45-55 psi
•Fluid Pressure 10 psi
•Fluid hose should be 3/8” (0.95 cm) I.D. with a maximum length of 50 feet (15.2 m). Pot should always have dual regula- tion and be kept at same elevation as spray gun.

Air Assisted Airless / Airless
•Tip .015”-.035” *dependent upon pressures and viscosity
•Pressure 1800-2500 psi
•Hose should be 3/8” (0.95 cm) I.D. minimum, but a ¼”
•(0.64 cm) I.D. whip end section may be used for ease of application. A maximum length of 100 feet (30.5 m) is suggested.
Cleanup

Clean tools/equipment immediately after use with water when coating is still wet. When dry, use Butyl Cellusolve or MIBK. Follow mfg’s safety recommendations when using any solvent.
