Packaging
| SikaCor® SW-501 | 15 kg net. |
| SikaCor® Cleaner | 160 l and 25 l |
Colour
Black, redbrown, approx. RAL 7032, approx. RAL 9002
Slight colour deviations are possible due to raw material characteristics.
SikaCor® SW-501 tends to chalking and yellowing if exposed to weathering.
In case of higher requirements regarding colour fastness, SikaCor® EG-4 or SikaCor® EG-5 respectively are recommended as top coats.

Application
Mixing ratio
Components A : B |
By weight | 80 : 20 |
By volume | 2.5 : 1 |
Material temperature
Min. + 20°C
Relative air humidity
Max. 85 %, except the surface temperature is significantly higher than the dew point temperature, it shall be at least 3 K above dew point.
The surface must be dry and free from ice.
Under unfavourable conditions, e.g. influence of high air humidity on the fresh coating, surface defects may occur. However, this will not effect the quality.
Surface temperature

At + 30°C | ~20 min |
Drying stage 6
| Dry film thickness 500 μm | |
| + 5°C after | 48 h |
| + 23°C after | 12 h |
| + 40°C after | 3 h |

Waiting time to overcoating
Min. Until drying stage 6 is achieved.
Max. 3 months
In case of longer waiting times please contact us.
Drying time
Final drying time
At + 20°C final curing is reached after 1 week.
Material also cures under water.
Consumption
Theoretical material-consumption / coverage without loss for medium dry film thickness:
| Dry film thickness | 500 |
| Wet film thickness | 500 |
| Consumption | ~0.700 kg/m2 |
| Coverage | ~1.45 m2/kg |
SURFACE PREPARATION
Steel:
Blast cleaning to Sa 2 ½ according to ISO 12944-4.
Free from dirt, oil and grease.
Average roughness depth RZ ≥ 50 microns
MIXING
Stir component A thoroughly using an electric mixer (start slowly, then increase up to approx. 300 rpm). Add component B carefully and mix both components very thoroughly (including sides and bottom of the container). Mix for at least 3 minutes until a homogeneous mixture is achieved. Material temperature should be 20-30°C after the mixing procedure. Fill mixed material into clean container and mix again shortly as described above. During mixing and handling of the materials always wear protective goggles, suitable gloves and other protective clothing.
APPLICATION
The method of application has a major effect on achieving uniform thickness and appearance. Spray application will give the best results. The indicated dry film thickness is easily achieved by airless spray. In case of application by roller or brush, additional applications may become necessary to achieve the required coating thickness, depending on type of construction, site conditions, colour shade etc. Prior to major coating operations a test application on site may be useful to ensure the selected application method will provide the requested results.
Airless-spraying:
- Efficient airless equipment
- Pressure min. 180 bar
- Diameter of hoses min. 10 mm (⅜ inch)
- Nozzle size 0.45 - 0.66 mm (0.021 - 0.026 inch)
- Spraying angle 40° - 80°
Depending on object conditions an adequate flow consistency can be achieved by a combination of:
- Using isolated hoses and
- Using an inline heater
By brush and roller:
- Possible on small areas or for stripe coatings
- We recommend the use of Sika Poxicolor® SW for large areas
