Sherwin-Williams JETFlex Single Component Water Reducible Polyurethane Dispersion
Sherwin-Williams Jet Glo® Express Conventional Paint With actual performance similar to solvent-based polyurethanes, JETFlex? Water-Reducible Polyurethane Dispersion is particularly reliable for plastic, metal and composite finishes. It offers outstanding solvent and chemical resistance. This low VOC, one-component coating is ideal for cabin interior reworks where solvent emissions can be an issue.
Application InstructionsSurface Preparation
General: Surface should be free of grease, dirt, fingerprints, rust and other foreign matter to insure optimum adhesion.
Plastic: Clean thoroughly to remove contaminants and mold release agents. Use isopropyl alcohol or other suitable solvent cleaner. If necessary, prime with JetFlex™ Primer CM0480930 to obtain adhesion. JetFlex® WR Spray Fil CM0481505 may be used for adhesion and filling on plastic substrates. Test system integrity before use or consult your Sherwin-Williams aerospace representative for additional information.
Metals: Chemical treatment such as Zinc or iron phosphate is recommended. Prime with JetFlex® Primer CM0480930 if required.
JetFlex® WR is a single component product. No mixing is required. Material should be stirred prior to using. Do not shake.
Water reducible coatings should be applied at high viscosity. They atomize very easily at higher viscosity. Do not use a viscosity cup to measure viscosity. ONLY USE DI WATER FOR REDUCING VISCOSITY.
Basecoat / smooth coats may be applied by conventional, airless, air assisted airless, HVLP or electrostatic methods. Texture coats must be applied using conventional or HVLP spray. Please consult your Sherwin-Williams representative for specific equipment settings.
Dry times are based on the dry film thickness of 1.2 mils (30 microns).
Air Dry Times (75°F / 25°C and 50% RH)
Force Dry (140°F/ 60°C)
For optimum hardness and cure, allow 2-4 weeks of air-drying for 1.5 –2.0 miles (38-50 microns) dry film. Heavier mils may require 6-8 weeks. Full cure is attained after 48 hours of additional air-drying.
NOTE: Good air movement and humidity control is necessary for proper drying of water reducible coatings. Cure test is 100 double rubs with MEK, slight burnishing.
Clean equipment and lines immediately with water. If dried, clean with a blend of water and ammonia as soon as possible. Only use after cleaning, Ketone grade solvents to clean equipment to prevent rusting.
NOTE: Because of the many types and compositions of plastic available, each user should test the coating on each substrate before production use. Customers must also verify FAR/JAR 25.853 regulation compliance on their substrate and system.
Eighteen month shelf life is applicable only for materials stored in unopened and undamaged original factory filled containers.
