High Elongation Properties Polyurea

Product Detail Information

POLYTOP SHE
High elongation properties polyurea

Description
POLYTOP SHE is two component, zero VOC's (Volatile Organic Compound), 100% solid. POLYTOP SHE may be applied directly to most substrates, and where adhesion is critical a primer may be used.
Is a product mouth which is planned the quality of high modulus of elongation with importance.

Use

  • For waterproof coating on concrete and wood structures.
    (Airport, apartment, watertank, all most concrete structures).
  • For camical resistance area.
  • For oil resistance (oilproof) area.
  • For multi purpose protection coating.

Features

  • Zero VOC's (100% solid).
  • Short initial curing time (30sec).
  • High tensile strengh and elongation.
  • Cures at -25°F to 300°F.
  • Excellent resistance to Thermal Shock.
  • Excellent resistance to solvent.
  • Excellent resistance to oil and acid(chemical).
  • Excellent bond strength to properly prepared surfaces.

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" 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 HE "A" is available in 200L steel drums and "B" is in 200L steel drums.
