~1.4 kg/l

~55 % by volume

~70 % by weight

Weather, water, sewage, seawater, smoke, de-icing salts, acid and lye vapours, oils, grease and short term exposure to fuels and solvents.

Dry heat up to + 150°C, short term up to + 200°C
Damp heat up to approx. + 50°C
In case of higher temperatures please consult Sika.

An exposure to high temperatures can lead to color changes.

Sika® Thinner EG

If necessary max. 5% Sika® Thinner EG may be added to adapt the viscosity.

Min. + 5°C

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.

Max. unlimited
Prior to further applications possible contamination must be removed.

Final drying time

Depending on film thickness and temperature full hardness is achieved after 1 - 2 weeks. Tests of the completed coating system should only be carried out after final curing.

Theoretical material-consumption/VOC without loss for medium dry film thickness:

Steel:
Blast cleaning to Sa 2 ½ according to ISO 12944-4.
Free from dirt, oil and grease.

Hot-dip galvanized steel, stainless steel and aluminium:
Free from dirt, oil, grease and corrosion products.
In case of permanent immersion and condensation the surfaces must be slightly sweep blasted with non-ferrous abrasives.

For contaminated surfaces e.g. galvanized or primed areas we recommend to clean with SikaCor® Wash.

Stir component A very 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. 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 clothings.

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. Adding solvents reduces the sag resistance and the dry film thickness. 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.

By brush and roller:
In order to achieve an attractive appearance in case of coatings containing micaceous iron oxide it is recommended to spray apply the last top coat or to brush or roll on in one direction only to avoid streaking.

Conventional high pressure spraying:

• Nozzle size 1.5 - 2.5 mm
• Pressure 3 - 5 bar
• Oil and water trap is compulsory
   

Airless-spraying:

• Pressure min. 180 bar
• Nozzle size 0.38 - 0.53 mm (0.015 - 0.021 inch)
• Spraying angle 40°- 80°

SikaCor® Cleaner

Spraying equipment must be rinsed with Sika® Thinner EG before using SikaCor® EG-4.
