Instructions for Use

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.

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 13 ºC and 35 ºC (55 ºF to 95 ºF). The minimum temperature of the paint components should be 13 ºC (55 ºF) 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 13 to 20 microns (0.5 to 0.8 mils). This can be accomplished with one medium coat with a 50% overlap.

These application guidelines represent PPG's best advice in standard conditions. Some parameters will be influenced by environmental conditions, equipment settings, and other variables.
