Description
PACKAGING & STORAGE
VpCI®-369 is available in 5 gallon (19 L) pails, 55 gallon (208 L) metal drums, liquid totes, and bulk.
VpCI®-369 is also available in 11 oz. (312 g) aerosol cans. To ensure best product performance, store in original packaging, indoors, and out of direct sunlight at 40-100 °F (4-38 °C).
Shelf life: 2 years
APPLICATION
Surface Preparation
Substrate should be free of grease, oil, dirt, fingerprints, drawing compounds, rust inhibitors (except Cortec® approved), 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® Technical 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 method. VpCI®-369 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 pressures 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 application. A maximum length of 100 feet (30.5 m) is suggested.
Cleanup
Clean tools/equipment immediately after use with Butyl Acetate when coating is still wet. For removal of VpCI®-369 applied to a metal surface, use a VpCI®-41x Series alkaline cleaner/degreaser. Follow mfg’s safety recommendations when using any solvent.
