PPG - Sigmacover 410 - Epoxy Coating is a two component, high solids, high build, epoxy coating designed for general purpose protection of steel and concrete structures exposed to atmospheric land or marine conditions.

Features

• General-purpose epoxy buildcoat in protective coating systems, for steel and concrete structures exposed to
  atmospheric land or marine conditions
• Excellent durability
• Can be recoated with various two-component and conventional coatings, even after long weathering periods
• Easy application by airless spray
• Good drying- and curing properties at low substrate temperature (down to –5°C (23°F))

Recommended Substrate Conditions and Temperatures

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

Instructions for use

Mixing ratio by volume: base to hardener 80:20 (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

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
