CONVERSELY POT LIFE AND CURE SLOWS AS TEMPERATURE COOLS. USE ACC 1030 ACCELERATOR BELOW 70 F TO ENSURE PROPER CURE. PROCEDURE: 1. To ensure primer attains the maximum wetting and adhesion the entire fabric covering must be cleaned with Air-Tech Fabric Wash (RF 4020 Rev. 3). Allow it to dry 30 minutes before application of the primer. 2. Although it is possible to spray all three coats in succession, color coats stand up better if one applies two coats of primer then wait overnight, lightly sand and then apply the third coat of primer. Spray good wet coats but don’t attempt to load up the primer; this will only retard cure.
If additional coats are applied to fill weave or hide tapes wait until previous coats are fully cured! Apply coats as wet as possible to ensure good soakage into the fabric weave. It is permissible to apply the first coat with a brush, usually on fine weaves; thin this coat to avoid brush marks! Notes: a. Primer base should be mixed in paint shaker prior to use. b. RT 4070 Rev. 4 thinner used at temp. below 85F; RT 4085 Rev. 4 above 85F. c. Set air pressure at 35 psi at the gun. 3. If any areas require sanding let primer cure for 12 hours. Use 320 – 380 wet sandpaper and use Scotchbrite pad #7447 over rib stitches, rivets etc. 4.
Recoating can be done anytime after 12 hours up to one week without sanding. 5. Ventilate all cavities to remove solvent vapors. Remember on fabric evaporation takes place inside the part as well as outside. These vapors must be removed. 6. Primed surfaces are ready for Air-Tech color coat. Don’t topcoat unless these undercoats are cured; in other words don’t rush it. SPECIFICATIONS: DRY FILM – 1.5-2 MILS % SOLIDS (SPRAYABLE) – 46%+ WT/GAL – 11.3 LB.
