    Features

    • Dry heat resistance up to 600°C (1112°F)
    • No heat cure necessary between coats
    • To be used for the internal and external protection of steel surfaces
    • Excellent resistance against weathering
    • Also suitable on top of zinc silicate primer
    • A minimum drying time of 3 days at 20°C (68°F) should be allowed before exposure to heat

    Recommended Substrate Conditions and Temperatures

    Substrate conditions

    • Steel; blast cleaned to ISO Sa 2½ or SSPC-SP-10, blasting profile 25 – 50 µm (1.0 – 2.0 mils)
    • Suitable coating (zinc silicate primer) must be dry, free from any contamination and zinc salts
    • Stainless steel; degreased and sweep blast (SSPC SP-16) cleaned to roughness of 40 – 70 µm (1.5 – 2.8 mils) with nonferrous abrasive

    Note: The maximum continuous dry heat temperature when power tool treated surface (ISO-St3) is 400°C

    Substrate temperature and application conditions

    • Substrate temperature during application should be at least 3°C (5°F) above dew point

    Instructions For Use

    • Power agitate to uniform consistency
    • Application with airless equipment is possible, but be careful not to apply more than specified thickness
    • When applying more than one coat, it is recommended that the total dry film thickness of SIGMATHERM 540 does not
      exceed 80 µm (3.1 mils)

    Air spray

    Recommended thinner

    No thinner should be added

    Nozzle orifice

    1.5 – 2.0 mm (approx. 0.060 – 0.079 in)

    Nozzle pressure

    0.3 - 0.4 MPa (approx. 3 - 4 bar; 44 - 58 p.s.i.)

    Brush/roller

    • For Roller application the best results will be obtained by using fine foam type rollers
