Product Compatibility:

CA8200 topcoats are compatible with the following primers:

• DMS 1786 • MIL-PRF-85582

• MIL-P-53022 • MMS-423

Surface Preparation and Pretreatments

CA8200 high solids topcoats can be applied over clean, dry, and intact Desoprime™ epoxy and Koroflex® primers. Desothane® HS topcoats may be applied over the primer with no abrasion if the primer was applied between 4 and 48 hours before top coating.

If it is longer, then abrade the primer surface and clean the surface with Desoclean™ 110 mild solvent cleaner. For further information, refer to the Technical Data Sheet for the above mentioned primers.

Instructions for Use

Mixing Instructions:

Prior to mixing, thoroughly shake the base component. Add the activator to the base component and stir well. Maintain constant agitation for 10 minutes to ensure proper mixing.

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° and 35°C (55° to 95°F). The minimum temperature of the paint components should be 13°C (55°F) prior to mixing.

Induction Time:

Application Guidelines

Recommended Application Conditions:

Temperature 15 - 30°C (59 - 86°F) Relative Humidity 20 - 90%

Application:

Ground the aircraft and the application equipment before top coating. Stir the topcoat slowly during the application. The suggested film thickness is 50 to 100 microns (2.0 to

4.0 mils). For gloss and semi-gloss topcoats this can be accomplished by two or three medium coats with a 50% overlap. With the flat and gunship/matte coatings it may be applied with a heavy cross coat or 2 coats. Note the first coat should be allowed to tack up before applying the second coat. If the second is applied before the first coat has tacked up, sagging may occur. If the first coat is dry hard, a heavy orange peel in the second coat may occur.

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

Note: The cure rates of CA8200 topcoats are not affected by humidity.

Note: The times listed above are dependent upon film thickness, airflow, and spray technique. Lower film thickness, better airflow, spraying “dry” will decrease the dry-to-tape, and time between coats.
