    PPG - Sigmadur 550H is a twin pack, high-solids, high-build polyurethane finish with Excellent resistance to atmospheric exposure conditions

    Features

    • Good color and gloss retention
    • Cures at temperatures down to -5°C (23°F)
    • Resistant to splash of mineral and vegetable oils, paraffins, aliphatic petroleum products and mild chemicals
    • Can be recoated even after long atmospheric exposure
    • Good application properties by airless, brush and roller
    • High film build-up to 150 µm (6.0 mils) for one coat
    • Can be applied direct to metal
    • Drying and curing times can be reduced significantly using PPG 866M ACCELERATOR

    Recommended Substrate Conditions and Temperatures

    Substrate conditions

    • Steel; blast cleaned to ISO-Sa2½, blasting profile 40 – 70 µm (1.6 – 1.8 mils), or powertool cleaned to ISO-St3
    • Compatible previous coat must be dry and free from any contamination

    Substrate temperature and application conditions

    • Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
    • Substrate temperature during application and curing down to -5°C (23°F) is acceptable; provided the substrate is free from ice and dry
    • Relative humidity during application and curing should not exceed 85%
    • Premature exposure to early condensation and rain my cause color and gloss change

    Instructions For Use

    Mixing ratio by volume: base to hardener 87:13

    • Do not thin more than is required by appropriate application property
    • Adding too much thinner results in reduced sag resistance
    • Thinner should be added after mixing the component
