Description

PPG SigmaZinc 19 is a one-component, zinc-rich epoxy primer with good anti-corrosive properties, and whilst designed for repair of two-component zinc epoxy primers and zinc silicate primers, PPG SigmaZinc 19 can also be used as a reconditioner for aged, derusted and galvanised steel.



Top Features & Benefits


  • Dry film contains 90% zinc by weight
  • Dries at temperatures down to –10°C (14°F)
  • Dry heat resistance 125°C (260°F) with peaks up to 175°C (350°F)
  • The superimposed system must be unsaponifiable
  • Quick-drying, can be overcoated after a short interval



Preparation & Application


Recommended Substrate Conditions and Temperature

  • Steel; blast cleaned to ISO-Sa2½, blasting profile 40 – 70 µm (1.6 – 2.8 mils)
  • Aged hot-dip galvanized steel with rusty spots; thoroughly derusted to ISO-St3 or ISO-Sa2½, blasting profile 40 – 70 µm (1.6 – 2.8 mils)
  • Zinc rich epoxies and zinc silicates must be dry and free from any contamination
  • Substrate temperature during application at -10°C (14°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

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).

 

Air Spray

Recommended thinner: PPG Thinner 91-79

Volume of thinner: 20 - 25%, depending on required thickness and application conditions

Nozzle orifice: 1.5 – 3.0 mm (approx. 0.060 – 0.110 in)

Nozzle pressure: 0.2 - 0.3 MPa (approx. 2 - 3 bar; 29 - 44 p.s.i.)

 

Airless Spray

Recommended thinner: PPG Thinner 91-79

Volume of thinner: 20 - 25%, depending on required thickness and application conditions

Nozzle orifice: Approx. 0.43 mm (0.017 in)

Nozzle pressure: 10.0 - 15.0 MPa (approx. 100 - 150 bar; 1451 - 2176 p.s.i.)

 

Brush/Roller

Recommended thinner: PPG Thinner 91-79

Volume of thinner: 0 – 3%

 

Cleaning Solvent

PPG Thinner 90-53

 

Notes:

  1. Zinc rich primers can form zinc salts on the surface; preferably they should not be weathered for long periods before overcoating.
  2. An interval of several months can be allowed under clean interior exposure conditions.
  3. In clean exterior conditions, a maximum interval of 14 days can be tolerated, but in industrial or marine conditions this interval should be reduced to the practical minimum.
  4. Before overcoating visible surface contamination must be removed by high-pressure water cleaning, sweep blasting or mechanical cleaning.
  5. When a long overcoating interval is required, it is recommended to overcoat SIGMAZINC 19 as soon as possible with a suitable sealer coat.

 

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.
