Film Thickness Range

Note: Maximum DFT when brushing: 200 μm (8.0 mils)
Measuring wet film thickness
- A difference is often obtained between the measured apparent WFT and the real applied WFT. This is due to the thixotropy and the surface tension of the paint, which retards the release of air, trapped in the paint film for some time.
- Recommendation is to apply a WFT, which is equal to the specified DFT plus 60 μm (2.4 mils).
Maximum Dry Film Thickness
- Because of low initial hardness the DFT cannot be measured within some days, due to the penetration of the measuring device into the soft paint film.
- The DFT should be measured using a calibration foil of known thickness placed in between the coating and the measuring device.

Surface Preparation
- Steel; blast cleaned to ISO-Sa2½, blasting profile 50 – 100 μm (2.0 – 4.0 mils).
- Steel; blast cleaned to ISO-Sa2 or power tool cleaned to ISO-St2 for good corrosion protection.
- Coated steel; hydro jetted to VIS WJ2/3 L (blasting profile 50 – 100 μm (2.0 – 4.0 mils).
- Previous coat of approved coating must be dry and free from any contamination.
- Pitted steel; blast cleaned to ISO-Sa2½ is recommended.
- Suitable primer; SIGMACOVER 280
- Suitable for damp surfaces
Substrate Temperature and Application Conditions
- Substrate temperature during application and curing should be above 5°C (41°F).
System Specification
- SIGMAGUARD 603: 1 x 300 μm (12.0 mils)
Application Methods
Mixing Ratio By Volume: Base To Hardener 80:20 (4:1):
- The temperature of the mixed base and hardener should preferably be at least 20°C (68°F)
- At lower temperature, the viscosity will be too high for spray application.
- No thinner should be added.
Induction Time:
- None
Airless Spray:
- Use heavy-duty, single-feed, airless spray equipment, preferably 60:1 pump ratio and suitable high-pressure hoses/in-line heating or insulated hoses may be necessary to avoid cooling down of paint in hoses at low air temperature.
- In-line heating or insulated hoses may be necessary to avoid cooling down of paint in hoses at low air temperature.
- Application with 45:1 airless spray equipment is possible, provided in-line, heated high-pressure hoses are used.
- Length of hoses should be as short as possible.
- Recommended Thinner: No thinner should be added
- Nozzle Orifice: Approx. 0.53 – 0.64 mm (0.021 – 0.025 in)
- Nozzle Pressure: At 20°C (68°F) paint temperature min. 28.0 MPa (approx. 280 bar; 4061 p.s.i.). At 30°C (86°F) min. 22.0 MPa (approx. 220 bar; 3191 p.s.i.)
Note: In case of using 45:1 airless spray equipment, the paint must be heated to approximately 30°C (86°F) in order to obtain the right application viscosity.
Brush/Roller:
- For stripe coating and spot repair only
Cleaning Solvent: THINNER 90-53 or THINNER 90-83
Note: All application equipment must be cleaned immediately after use. Paint inside the spraying equipment must be removed before the pot life has been expired.
