PPG - Sigmashield 460 is a two-component, high solids glass flake reinforced polyamine cured epoxy coating that offers long-term protection at areas subject to heavy wear and tear

Features

• Excellent abrasion and impact resistance
• Suitable for use on ice-going vessels
• Excellent resistance to corrosion
• Long-term protection at areas subject to heavy wear and tear
• Resistant to splash and spillage of a wide range of chemicals
• Very low water permeability, due to glass flake barrier

Recommended Substrate Conditions and Temperatures

Substrate conditions

• Suitable primer : SIGMACOVER 280 or SIGMAPRIME 200 is recommended
• Previous coat must be dry and free from any contamination

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 75:25 (3:1)

• 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
• Very good mechanical mixing of base and hardener is essential
• Thinner should be added after mixing the components
• Filters should be removed from spray equipment

Induction time

None

Pot life

1.5 hours at 20°C (68°F)

Note: See ADDITIONAL DATA – Pot life

Air spray

Recommended thinner

THINNER 91-92

Volume of thinner

5 - 10%, depending on required thickness and application conditions

Nozzle orifice

1.5 – 2.0 mm (approx. 0.060 – 0.079 in)

Nozzle pressure

0.3 - 0.4 MPa (approx. 3 - 4 bar; 44 - 58 p.s.i.)

Airless spray

Recommended thinner

THINNER 91-92

Volume of thinner

0 - 5%, depending on required thickness and application conditions

Nozzle orifice

Approx. 0.53 – 0.79 mm (0.021 – 0.031 in)

Nozzle pressure

19.0 - 22.5 MPa (approx. 190 - 225 bar; 2756 - 3264 p.s.i.)

Brush/roller

• Brush application only
• Only for touch-up and repair
• Due to thixotropy, it is difficult to obtain a smooth film by brush, although this does not affect performance

Cleaning solvent

THINNER 90-53
