TURBINE ENGINE CLEANER

PT-402 Acid Etching Primer, when properly reduced with PT-1045 Reducer, meets and exceeds MIL-C-8514C.PT-402 is a polyvinyl butyral zinc chromate formulation that may be used to prime all plain or plated metallic surfaces. Priming surfaces with PT-402 Acid Etching Primer prior to priming with epoxy primer MIL-PRF23377or by itself will ensure maximum adhesion and protection of all bake or air-dry finish coats (including lacquerfinish coats). The finely ground emulsions of zinc chromate pigments, resins and phosphoric acid hardeners are virtually non-settling. Once applied, the Acid Etching Primer requires no sanding and has a pot life of 8 hours. Extreme humidity can affect the bonding of the coating.

SURFACE PREPARATION INSTRUCTIONS

• Scuff the surface with scotch bright pads.
• Dust off the surface with an air hose and wand.
• Wipe of the substrate with IPA or Acetone to remove grime and oils
• Remove all remaining dust and debris by lightly wiping the substrate with a tack or “cheese” cloth

MIXING INSTRUCTIONS

• Shake component A in a paint shaker for 5 – 10 minutes for optimal results.
  ‍
• Admix by volume:
  ‍
• 1. Stir or shake both component “A” and “B” well before mixing
  ‍
• 2. Add 4 parts of Component “A” to 1 part of Component “B” by volume and stir thoroughly. Stir each well before mixing.

• 3. Reduce with PT-1045. Dilution ratio is 1 part admixed primer to 2 – 3 parts PT-1045.4. Mix only an amount that can be used in one day.

APPLICATION

This product can be applied using conventional air spray equipment, HVLP spray system. Please consult with a PTI representative for specific equipment recommendations and settings.

• 1. Make sure pots, guns, and lines are purged and cleaned.
• 2. Mix both base and catalyst thoroughly and filter/strain before spray application.
• 3. HVLP Spray Pressure: 7-10psi. Convention spray equipment 15-30psi
• 4. Always air-blow and tack wipe the surfaces to be painted. Aircraft should be grounded to prevent static.
• 5. Best application results: apply 1 fog/tack coat at 0.2 mil thickness.
• 6. Recommended Dry Film Thickness is 0.2 mils.

NOTE: Application of PTI products requires the use of all OSHA approved safety equipment, including proper ventilation. Additionally, PTI products require the recommended temperature/humidity conditions and film thickness ranges for optimal performance. The material, hangar, and aircraft skin temperatures should be no lower than 75⁰ F / 25⁰ C before, during and after application.DRYING & CURING SCHEDULEDry times are based on the dry film thickness of 0.2 mils (25-50 microns).
