A 6-page specification.                                                      Updated 22 November, 2011 …………………………………………………………………………………………………………………………..

Aviation epoxy two component zinc phosphate primer paint, high solids content, corrosion inhibiting primer base for ferrous and nonferrous metals in airplanes/missiles and space shuttles/stations.

Cat. Item no. : 670003

Epoxy paint rich with zinc phosphate, particularly strong with a unique molecular structure matches the requirements of the American federal standard device, manufactured in accordance with the requirements of the contents of zinc.

Paint creates a primer foundation layer with high adhesion to space aviation parts that maid of ferrous and nonferrous metals parts treated according to the U.S. Fed. St. Also used as the mid. layer “bridges” the old paint before recoat it with a polyurethane top aliphatic aviation CARC or camouflage paints.

  • The recommendations listed do not hold any responsibility for this product.
  • Theoretical and actual coverage area are different concepts, the actual coverage is affected by the required thickness of the layers, required number of layers, painting conditions including the amount of paint which spread in the air before touching the surface.

  • Paints that have been in stagnation or exposed to air more than needed could have their qualities changed.

Clarifications:

  • Storage room temperature 15°C to 25°C.
  • Over Spray: An effect which occurs in the spraying of paints application. A type of “dust” is created by dry gases of the air, which causing the paint particles to fall dry on the surface (hereafter the “effect”). The impact of this “effect” becomes stronger due to over pressure and heat, (most sprayers have a lever to control the pressure) To avoid the negative impact 0f the “effect”, the pressure of the spraying should be lowered to the necessary minimum! Another possibility is to increase the amount of the thinner in the mixture which would cause the paint particles to fall wetter on the surface.

An additional recommended possibility, to avoid this “effect”, is to add a retarder to the mixture which increases the duration period of the painting application, avoiding the paint to dry up, and enabling it to reach the surface wetter, thus a better painted smooth layer is formed.

  • Pot Life: The working time which is possible to paint a mixture of two components, A+B (or more) without spoiling the qualities of the paint or disqualifying the paint as “out of use”.
  • Spray: It is possible to spray with a sprayer that has a container holding the paint that sprays it with air pressure.
  • Airless: a device with a piston which compresses the air for spraying paints. The pressure might be high (over 100atm.) Don’t aim it at anyone
  • Surface preparations: the level of cleanness is determined by international standards. Surface preparations, including cleansing sand blasting, is important & critical factor in achieving an optimal result for painting adhesion on a certain surface. These standards are equally compared to the standards of the Swiss SA, the German-Din the U.S SSPC SP for each standard in any level there are indicators, for sale, in order to make visual comparison between the cleansing of the surface and the indicator.

Quality inspection:

  • Prior to the painting on large surfaces it is important to test the product on a small area, to be sure that the paint is compatible with the level of satisfactory.
  • Laboratory testing was made according to the standards institution specifications.
  • This “Data sheet” given as noncommittal information, the product above recommended for professional painting specialists. This information is not a substitute to personal guidance.
