Application

  • Mix ratio 1:1 , It must use spraying equipment for polyurea. And keep the pressure minimum 2000psi with heating to 65-70°C.(Pre heater temperature should be approx at 70-75°C and hose temperature
    should be at 65-75°C). These include GRACO, SPI company product . And Gun models include GRACO, SPI company product for polyurea spraying.
  • Component "B" must be mixed each day, while to spray.
  • Thinning is not required.
  • You check the "SSPC SP10" before start spraying.

Caution

  • Store in warm place preventing from freezing.
    Contents should not be exposed for a long time
  • In case of contact with skin and eyes, flush immediately with plenty of water and seek medical advice.
  • For further information, see the Material Safety Data Sheet

Packing

  • POLYTOP 500 "A" is available in 200L steel drums and "B" is in 200L steel drums.
