VpCI-396Moisture Cure Urethane Primer
PRODUCT DESCRIPTION:
VpCI®-396 is a fast drying, solvent-based moisture cure urethane one coat system (primer & 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. Can be matched to most custom colors.
PACKAGING & STORAGE
VpCI®-396 is available in 5 gallon (19 liter) pails. Partially used containers must be purged with nitrogen.
Product shelf life is 1 year.

APPLICATION
Surface Preparation
Substrate should be free of grease, oil, dirt, fingerprints, drawing compounds, rust inhibitors, or any other surface contam- ination 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® Technical Service 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®- 396 to aluminum, galvanized or plated substrates. When solvent based topcoats are applied over VpCI-396, compatibility must be checked. Cortec® recommended topcoats include VpCI®-280, 380, 381, 386, 387, 390, 392, 382, and 384.
Note: Make sure dew point is more than 5°F (2°C) less than air temperature for application. Humidity must be min. 20%, max. 80%. Power agitate to a uniform consistency using a “squirrel cage” type mixer, hand-held drill mixer, or other equivalent method. VpCI®-396 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 Butyl Acetate when paint is still wet. When dry, use Butyl Cellusolve or MEK. Follow mfg’s safety recommendations when using any solvent.
