Mixing Instructions |
N/A
1-Step Mixing (mixed in base container): Slowly add the entire catalyst component to the base component. Fill the can to the chime with distilled or deionized water. Secure the can lid and shake on paint shaker in an inverted position for 10 - 15 minutes. Do not shake longer than 15 minutes. Primer is now ready for use. Touch-up kits available in 2TU and 4TU configuration: Touch-up kit configuration consists of an inner cup, which contains the 44GN072CAT catalyst (or catalyst/acetone blend) located inside an outer cup (bottle) that contains the 44GN072 base component. To mix, remove lid, pour contents of inner cup (catalyst or catalyst/acetone blend) into outer cup (base), add supplied water. Replace lid and shake well by hand, approximately 2 minutes. Material is now ready to apply. Note: It is important to condition the paint for 24 hours prior to mixing by placing all materials in the shop or hangar, with ambient temperatures between 13º and 35ºC (55º to 95ºF). The minimum temperature of the paint components should be 13ºC (55ºF) prior to mixing. |

Applications |
N/A Ground the aircraft and the application equipment before priming. Stir the primer slowly during the application. The suggested film thickness is 15 to 22.5 microns (0.5 to 0.9 mils). This can be accomplished with one medium coat with a 50% overlap. |
Touch-Up-Kit Application |
N/A
After mixing the touch up kit, use a brush, roller or Preval® Sprayer to apply. These application guidelines represent PPG's best advice in standard conditions. Some parameters will be influenced by environmental conditions, equipment settings, and other variables. |
