VpCI®-386 is a fast drying, water-based acrylic one coat system (topcoat) that can be applied DTM (Direct to Metal) and provides protection in harsh, outdoor, unsheltered applications. The complex mixture of non-toxic, organic inhibitors offers protection that competes with most paints and zinc-rich primers. Provides multi-metal protection. Excellent UV resistance. VpCI®- 386 is weldable and can be used to keep surfaces corrosionfree prior to welding. Can be matched to most custom colors. NSN 8030-01-481-8897 (clear only).

APPLICATION
Surface Preparation
Substrate should be free of grease, oil, dirt, fingerprints, drawing compounds, rust inhibitors, or any other surface contamination that could affect adhesion. For production line applications, use VpCI®-440 or similar phosphatizing pre-treatment.
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.
A wash primer such as VpCI®-373 green applied at 0.5-1.0 mils (12.5-25 microns) is recommended before applying the VpCI®-386 to aluminum, galvanized or plated substrates. Other recommended primers include VpCI®-375, 395 and 396 depending on coating requirements. When solvent based topcoats are applied over VpCI®-386, compatibility must be checked.
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®-386 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 regulation 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 paint is still wet. When dry, use Butyl Cellusolve or MEK. Follow mfg’s safety recommendations when using any solvent.
