PPG SigmaCover 410 – High-Build Epoxy Buildcoat for Steel & Concrete (Formerly AmerCoat 410)

PPG SigmaCover 410 is a two-component, high-solids, high-build epoxy coating designed as a versatile buildcoat in protective systems for steel and concrete structures. Engineered for durability in both atmospheric land and marine environments, it performs exceptionally well in new construction and maintenance projects.

This reliable epoxy can be easily applied by spray, brush or roller, and its long recoat window allows overcoating with a wide range of two-component or conventional coatings, even after extended weathering. Available in both Micaceous Iron Oxide (MIO) and standard pigmented finishes, SigmaCover 410 provides excellent corrosion protection and long-term performance.

Key Features:

  • Two-component, high-solids, high-build polyamide-cured epoxy

  • Suitable for steel and concrete in atmospheric & marine environments

  • Easy application by spray, brush or roller

  • Available in MIO and conventional pigmented grades

  • No induction time – 6-hour pot life

  • Fast curing: Touch dry in 3 hours, fully cured in 7 days

  • Excellent durability with wide topcoat compatibility

  • Can be recoated even after long weathering intervals

Surface Preparation

Substrate conditions
• Suitable primer must be dry and free from any contamination
• Surface of previous coat should be sufficiently roughened if necessary
• When applied to zinc silicate, a mist coat and full coat technique is required
Substrate temperature
• Substrate temperature during application and curing down to -5°C (23°F) is acceptable; provided the substrate is free from ice and dry
• Substrate temperature during application and curing should be at least 3°C (5°F) above dew point

Technical Data

Pot life
6 hours at 20°C (68°F)
Note:
- See ADDITIONAL DATA – Pot life

Spreading rate and film thickness

DFT Theoretical spreading rate
75 µm (3.0 mils) 10.7 m²/l (428 ft²/US gal)
150 µm (6.0 mils) 5.3 m²/l (214 ft²/US gal)
200 µm (8.0 mils) 4.0 m²/l (160 ft²/US gal)

Directions for Use

Mixing ratio by volume: base to hardener 4:1
• The temperature of the paint 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 and slower cure
• Thinner should be added after mixing the components

Airless spray
Recommended thinner
THINNER 91-92
Volume of thinner
0 - 10%
Nozzle orifice
Approx. 0.46 – 0.53 mm (0.018 – 0.021 in)
Nozzle pressure
20.0 - 25.0 MPa (approx. 200 - 250 bar; 2901 - 3626 p.s.i.)
Brush/roller
• Application by brush may show brush marking, due to the thixotropic nature of the paint and is most suitable to
small areas, tight angle areas or for stripe coating or touch-up
• Application by roller will leave roller marking and is suitable for minimum DFT requirements only
• A roller suitable for epoxy application must be used
Recommended thinner
THINNER 91-92
Volume of thinner
0 – 5%
Cleaning solvent
• THINNER 90-53
