SikaCor® EG Phosphat

• Approved according to German standard ‘TL/TP-KOR-Stahlbauten’, page 87.

3 years from date of manufacture.

In originally sealed containers in a cool and dry environment.

~1.6 kg/l

~62 % by volume

~80 % by weight

Combined with 2-pack epoxy intermediate coats and 2-pack PUR top coats:

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

Dry heat up to +100 °C, short term up to +150 °C.
In case of higher temperatures please consult Sika Technical Department.

Sika® Thinner EG

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

In case of using SikaCor® EG Phosphat as weldable shop coating add approximately 20 % by weight Sika® Thinner EG.

+5 °C min. / +35 °C max.

Maximum 85 %, except the surface temperature is significantly higher than the dew point temperature, it shall be at least 3 °C above dew point.

+5 °C min. / +35 °C max.

Minimum waiting time until drying stage 6 is achieved to maximum 1 year. In case of longer waiting times please contact Sika Technical Department.

Make sure that all contamination is removed before overcoating with topcoats (see below: surface preparation).

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:

The dry film thickness of the primer coat does not respect the correction factors on rough surfaces according to ISO 19840.

With SikaCor® EG Phosphat up to 120 μm dry film thickness can be achieved by airless spraying.

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

For contaminated and weathered surfaces we recommend to clean with SikaCor® Wash.

Stir component A very thoroughly using an electric mixer (start slowly, then increase up to approximately 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.

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

Conventional high pressure spraying:

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

Airless-spraying:

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