    PPG - Sigmatherm 230 is a two-component, high-build, heat-resistant epoxy phenol novolac coating that provides a corrosion resistant barrier on carbon steel and stainless steel under thermal insulation.

    Features
    • Suitable as heat resistant system under insulation up to 230°C (450°F)
    • Suitable for use in cryogenic conditions
    • Passes cryogenic cyclic test down to -196°C (-321°F)
    • Excellent protection and resistance against corrosion and severe chemicals
    • Excellent resistance to thermal shock during rapid wet & dry cycling
    • Meets CS-1, 3 and 4 for carbon steels under thermal insulation according to NACE SP0198-10
    • Meets SS-1, 2 and 3 for stainless steels under thermal insulation according to NACE SP0198-10
    • No post-curing is required to obtain mechanical strength
    • Can be applied on hot substrate up to 150°C (302°F)

    Recommended Substrate Conditiond and Temperatures

    Substrate conditions

    • Steel; blast cleaned to ISO-Sa2½, blasting profile 40 – 70 µm (1.6 – 2.8 mils)
    • The substrate must be perfectly dry before and during application of SIGMATHERM 230
    • Stainless steel ; degrease with solvent and sweep blast, SSPC SP-16 with blasting profile 40 – 100 µm (1.5 – 4.0 mils)

    Substrate temperature and application conditions

    • Substrate temperature during application and curing should be above 5°C (41°F)
    • Substrate temperature during application and curing should be at least 3°C (5°F) above dew point

    Instructions For Use

    Mixing ratio by volume: base to hardener 87:13

    • The temperature of the mixed base and hardener should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity.
    • Adding too much thinner results in reduced sag resistance
    • Thinner should be added after mixing the components
