Surface Preparation and Pretreatments

N/A 03 Series flat polyurethane military topcoats can be applied over clean, dry, and intact Desoprime™ epoxy and Koroflex® primers. 03 Series polyurethane military 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

N/A Thoroughly stir or shake the base component (Part A) before combining to ensure all solids are completely dispersed. Add one volume of catalyst component (Part B) to the three parts of base component (Part A). Do not use the catalyst component (Part B) from another color. Mix by hand stirring, paint shaker or mechanical mixing to ensure the base/catalyst mixture is homogeneous. Do not shake or mechanically mix material for longer than 10 minutes. Thinners are not required for the mixed material. Available thinners for polyurethanes are MIL-T-81772B Type I* (IS-213), VOC Exempt Reducer (IS-256) and Low HAPS thinner (IS-260). Do not add thinners to attempt to compensate for coatings beyond its useful pot life

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 Coating may be applied over properly cleaned composite surfaces, epoxy primer coatings or polyurethane coatings. Apply the topcoat using two coats to a total dry film thickness of 1.7 - 2.3 mils. Apply the first coat as a light (mist) coat. Allow the coat to set for 30 - 60 minutes (depending on airflow, temperature and humidity) before applying the second coat to permit solvent evaporation. Apply the second coat in a full wet coat to achieve the desired film thickness. Conventional, Air, Air Assisted Airless, HVLP, Electrostatic spray equipment may be used to apply this material. For your application, please contact the equipment manufacturer for more specific information on Conventional, HVLP or Electrostatic spray applications, and recommendations on hose diameter and lengths.

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