APPLICATION
Surface Preparation
Substrate should be free of grease, oil, dirt, fingerprints, drawing compounds, rust inhibitors (except Cortec® ap- proved), or any other surface contamination that could affect adhesion. Cortec® recommends a minimum of a SSPC-SP1 over painted surfaces. For bare metal applications, Cortec® recommends a NACE #3/ SSPC-SP6. Consult Cortec® Tech- nical Service and/or test system adhesion prior to full scale application.

Power agitate to a uniform consistency using a “squirrel cage” type mixer, hand-held drill mixer, or other equivalent meth- od. VpCI®-368 can be applied by spray, roll, brush, or dip.

Typical Equipment Setups

HVLP / Conventional Spray
•Tip 0.02”-0.11” (0.5-2.8 mm)* dependent upon pressures and viscosity
•Air Pressure 45-55 psi
•Fluid Pressure 10 psi
•Fluid hose should be ⅜” (0.95 cm) I.D. with a maximum length of 50 feet (15.2 m). ¼” (0.64 cm) I.D. fluid hose can be used but pressures may need to be adjusted. Pot should always have dual regulation and be kept at same elevation as spray gun.

Air Assisted Airless / Airless
•Tip 0.015”-0.035” (0.38-0.89 mm)* dependent upon pres- sures and viscosity
•Pressure 1800-2500 psi
•Hose should be ⅜” (0.95 cm) I.D. minimum, but a ¼” (0.64 cm) I.D. whip end section may be used for ease of applica- tion. A maximum length of 100 feet (30.5 m) is suggested.

*All tests performed after a 7 day cure at ambient temperature

Cleanup
Clean tools/equipment immediately after use with butyl acetate when coating is still wet. When dry, use butyl cellu- solve or MEK. Follow mfg’s safety recommendations when using any solvent.
