PPG - Sigma EP 110 Primer is a two component zinc phosphate blast primer & sealer that has excellent rust preventing properties in industrial or coastal atmospheres.

Features

• Cures at temperatures down to 5°C (41°F)

• Excellent adhesion to steel
• Epoxy blast primer for steel
• Registered as Highway Agency item 110
• Approved Network Rail RT 98 item 7.1.2

Recommended Substrate Conditions and Temperatures

Substrate conditions

• Steel; blast cleaned to ISO-Sa2½, blasting profile 50 – 100 µm (2.0 – 4.0 mils)
• Galvanized steel; pre-treated with Sigma Etch

Substrate Temperature & Application Conditions

• Substrate temperature during application and curing down to 5°C (41°F) is acceptable
• Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
• Relative humidity during application and curing should not exceed 85%

Instructions for Use

Mixing ratio by volume: base to hardener 75:25 (3:1)

• 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 and slower cure
• Thinner should be added after mixing the components
