    PPG - Sigmacover 350 - Epoxy Primer is a two-component, high build polyamide cured epoxy primer/coating for wide use in Marine and Protective Coatings.

    Features

    • Surface tolerant primer/coating for wide use in Marine and Protective Coatings.
    • Marine use: suitable on topsides, decks, superstructures and cargo holds
    • Excellent corrosion resistance
    • Compatible with various aged coatings
    • Suitable as floor coating for pedestrian traffic with dry to walk on time of 6 hours at 20°C (68°F)
    • Good impact and abrasion resistance
    • Smooth film, easy to clean
    • Resistant to splash and spillage of a wide range of chemicals

    Recommended Substrate Conditions and Temperatures

    Substrate Conditions

    • Steel; blast cleaned to ISO-Sa2½ for excellent corrosion protection, blasting profile 40 – 70 µm (1.6 – 2.8 mils)
    • Steel; blast cleaned to ISO-Sa2, blasting profile 40 – 70 µm (1.6 – 2.8 mils) or power tool cleaned to minimum ISO-St2 for good corrosion protection
    • Coated steel; hydrojetted to VIS WJ2/3L
    • Surface must be dry and free from any contamination
    • Existing sound epoxy systems and most sound alkyd coating system; sufficiently roughened

    Substrate Conditions of Concrete for Thinned Version

    • Dried for at least 28 days in good ventilation conditions
    • Moisture content should not exceed 4.5%
    • Concrete must be sound, dry, free from laitance and any contamination
    • Rough surface; eventually abraded by power tool or diamond abrading tool

    Coated Concrete

    • Existing sound coating systems; sufficiently roughened, dry and cleaned
    • To ensure compatibility, rub the existing coating with a cloth with Xylene or MEK for 10 seconds, and remove existing coatings if dissolving occurs
    • Rough surface; eventually abraded by power tool or diamond abrading tool

    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 80:20 (4:1) 

    • 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
