44GN011 Water Reducible Epoxy Primer

44GN011 is a water reducible, chemically cured, two-component epoxy polyamide primer. 44GN011 is formulated to protect the structural interior of aircraft from corrosion.

  • Corrosion inhibiting
  • Compatible with epoxy and urethane interior topcoats
  • Excellent adhesion to aluminum and composite surfaces
  • Chemical and solvent resistant
  • Resistant to immersion in hydraulic fluids, lubricating oils, phosphate ester based hydraulic fluids and distilled water

44GN011 Water Reducible Epoxy Primer is compatible with the following topcoat specifications:
-BMS 10-11 Type II
-BMS 10-60 Type I & II

Instructions for Use

Mix ratio (by volume):

44GN011 (base component)  2 parts

44GN011CAT (catalyst component)  1 part
Reducer (Distilled or Deionized water)  4 ½ parts water by volume (approximately 150%)

Mixing Instructions: 

Stir or shake the base component. Do not stir or shake the base component longer than 5 minutes. Pour two volumes of base component into a separate clean container. Slowly add the one volume of catalyst to the two volumes base component. 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 5 minutes. Add approximately 4.5 volumes (150%) of distilled or deionized water. Slowly add the water in one-third increments, mixing thoroughly after each addition, until fully incorporated and homogeneous. Be sure to scrape the sides and bottom of the container.

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

Surface Preparation and Pretreatments

44GN011 primer can be applied over clean, dry, intact aluminum and composite surfaces. Aluminum surfaces shall be treated with materials conforming to MIL-DTL-5541 or equivalent.

Safety Precautions: Comply with all local safety, disposal and transportation regulations. Check the Safety Data Sheet (SDS) and label of the individual products carefully before using the products. SDS’s are available on request.
