PPG SigmaCover 350 – High-Build Anticorrosive Epoxy Primer/Coating (Available in 2,600+ Colours)
PPG SigmaCover 350 is a two-component, high-build polyamide-cured epoxy primer/coating engineered for outstanding anticorrosive performance across a wide range of marine and protective coating environments. Ideal for steel and concrete, it is widely used on topsides, decks, superstructures, and cargo holds, offering long-term durability and excellent resistance to chemical exposure, abrasion and impact.
With availability in over 2,600 colours-including RAL, BS, NCS, and the latest NCS 2050 range-SigmaCover 350 is an exceptionally versatile option for both new construction and maintenance coating systems. Its surface-tolerant formulation, fast curing properties and compatibility with many aged coatings make it a reliable, high-performance choice for demanding environments.

Surface Preparation
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 ISOSt2 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

Spreading rate and film thickness
DFT Theoretical spreading rate
100 µm (4.0 mils) 7.2 m²/l (289 ft²/US gal)
125 µm (5.0 mils) 5.8 m²/l (231 ft²/US gal)
150 µm (6.0 mils) 4.8 m²/l (192 ft²/US gal)
Directions for Use
Mixing ratio by volume: base to hardener 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
