PPG - SigmaFast 20 - Zinc Phosphate Primer is a high-build zinc phosphate primer, based on modified alkyd resin that has good anticorrosive properties under atmospheric conditions

Features

• Fast-drying
• Fast-handling
• Recoatable with most one- and two-component coatings
• Suitable for atmospheric exposure conditions
• Lead- and chromate free
• Can be specified as a single coat, direct-to-metal system for ISO 12944 C1 and C2 environments

Recommended Substrate Conditions and Temperatures

Substrate conditions

• Steel; blast cleaned to ISO-Sa2½
• Steel; power tool cleaned to min. ISO-St2
• Shop primed steel; sweep blasted or power tool cleaned to SPSS-Ss or SPSS-Pt2

Substrate temperature

• 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

• Stir well before use
• 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
• Adequate ventilation must be maintained during application and curing (please refer to INFORMATION SHEETS 1433 and 1434)
