PPG SigmaZinc 105 is a two-component, zinc epoxy steel primer with excellent anti-corrosive and application properties.
Top Features & Benefits
- Quick-drying, can be overcoated after 25 minutes
- Excellent application properties
- Cures at temperatures down to -5°C (23°F)
- Flat finish
Preparation & Application
Recommended Substrate Conditions and Temperatures
Substrate Conditions
- Steel; blast cleaned to ISO-Sa2½, blasting profile 40 – 70 µm (1.6 – 2.8 mils)
Substrate Temperature and Application Conditions
- 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 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
Pot Life
4 hours at 20°C (68°F)
Air Spray
Recommended Thinner: PPG Thinner 21-06
Volume of thinner: 15 - 20%, depending on required thickness and application conditions
Nozzle orifice: 1.6 mm (approx. 0.063 in)
Nozzle pressure: 0.3 - 0.6 MPa (approx. 3 - 6 bar; 44 - 87 p.s.i.)
Airless Spray
Recommended thinner: PPG Thinner 21-06
Volume of thinner: 5 - 15%, depending on required thickness and application conditions

Brush/Roller
Recommended thinner: PPG Thinner 21-06
Volume of thinner: 0 – 5%
Cleaning Solvent
PPG Thinner 90-53
Safety Precautions
For paint and recommended thinners see INFORMATION SHEETS 1430, 1431 and relevant Material Safety Data Sheets. This is a solvent-borne paint and care should be taken to avoid inhalation of spray mist or vapor, as well as contact between the wet paint and exposed skin or eyes.

Notes:
Surface should be dry and free from any contamination. An interval of several months can be allowed under clean interior exposure conditions. Zinc primers can form zinc salts on the surface; preferably they should not be weathered for long periods before overcoating. Before overcoating any visible surface contamination must be removed by sandwashing, sweep blasting or mechanical cleaning
