Asphalt Flex–aviation use

Polyurethane super flexible coating for asphalt surfaces


A two component special polyurethane coating to form a thick, strong & flexible layer, by pouring it on asphalt surfaces.

Useful for parking areas such as cars, trucks, airplanes in airports.

It has fuel and chemical resistance & sealing ability as well as durability in harsh and extreme conditions.

It has a self-leveling property and can produce an unlimited thickness layer. It absorbs mechanical noise and hits and has an excellent erosion durability. It enables the sealing of the cracks, spreading slits and holes by pouring the product directly in to them.

Due to its special molecular structure the product forming a flexible & a strong layer which prevents breaks & cracks for along a period!

Application methods:

  • Pour \ spread or spray with airless (high pressure ratio) for thin coating.


  • No thinning needed. To coat small areas it is required to make a suitable amount of mixture for immediate use.

Surface preparations:

  • Concrete: apply on absolutely clean surfaces. Spread epoxyden floor primers (see product application) in case the concrete absorbed the primer leaving crumbs apply another layer of primer floor.
  • Asphalt: clean thoroughly with high water pressure in order to get an absolutely clean surface. Wait until the surface completely dries.
  • Aluminum: apply a layer of Epoxyden Stronzium chromate (see instructions for the product)
  • Steel: apply a layer of Epoxyden 19.


  • Make sure that the base layer is dry, clean; dirt, dust and grease free.
  • Open carefully ‘A’ +’B’ sections of the Asphalt flex and pour in the ratio 3:1 the required amount according to the volume = surface calculation for one layer coating.
  • Stir the mixture well with a slow mixer and immediately pour on the surface. With a large wiper spread the mixture evenly on the entire surface. For large surfaces a portable cement mixer could be used in order to make over 200 liters at once in case that the material could be spread on the entire surface within 30 minutes.

  • 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.
  • The information listed in this section is based on experience and accumulating data, Denber inc., has the right to change the information listed at any time.
  • Paints that have been in stagnation or exposed to air more than needed could have their qualities changed.


  • 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 results 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.
