DescriptionSigmaCover 350, a two-component, high-build polyamide cured anticorrosive epoxy primer/coating for wide use in Marine and Protective Coatings such as topsides, decks, superstructures and cargo holds. The fast-curing primer can be used on concrete and steel, with good impact and abrasion resistance and excellent corrosion resistance, applied by spray, brush or roller.Available in Grey, Aluminium, and the full RAL and BS range (more than 350 colours).PRINCIPAL CHARACTERISTICSSurface tolerant primer/coating for wide use in Marine and Protective Coatings.Marine use: suitable on topsides, decks, superstructures and cargo holds • Good impact and abrasion resistanceFast-curingSmooth film, easy to cleanCompatible with various aged coatingsExcellent corrosion resistanceResistant to splash and spillage of a wide range of chemicalsRECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES Substrate conditionsSteel; 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 protectionCoated steel; hydrojetted to VIS WJ2/3LSurface must be dry and free from any contaminationExisting sound epoxy systems and most sound alkyd coating system; sufficiently roughened Substrate temperature and application conditionsSubstrate 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 viscosityAdding too much thinner results in reduced sag resistanceThinner should be added after mixing the components.
