Sika® Poxitar® F

• Coating based on epoxy resin for concrete protection according to EN 1504-2:2004, DOP, with CE-mark.

1 year

In originally sealed containers in a cool and dry environment.

~1.8 kg/l

~87 % by volume

~96 % by weight

Resistant to water, seawater, barnacles, diluted acids and lyes, neutral salts, mineral and fuel oils, grease, detergents etc.
Not resistant to exposure to benzene-hydrocarbons and tar oil.

Dry heat up to approx. + 100°C
Damp heat and warm water up to approx. + 60°C
Short term exposure up to approx. + 80°C
Not resistant to warm water at significant differential of temperature gradient!

Sika® Thinner S, only thin material where stated.
If necessary max. 5 % Sika® Thinner S may be added to adapt the viscosity.
In this case an immediate exposure to water is not possible.

If necessary the material components can be tempered.

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.

Under unfavourable conditions, e.g. influence of high air humidity into the fresh coating, surface damages (brown discolouration) and possibly little alligatoring may occur. However, this will not affect the quality.

Min. + 5°C

Waiting time between operations up to max. 150 μm dry film thickness:

If these maximum waiting times cannot be observed, the surface must be activated by sweep blasting to avoid intercoat adhesion problems.

Prior to application of the next coat a thorough dedusting is necessary.

Between SikaCor® Zinc R and Sika® Poxitar® F:

24 h at + 20°C (see product data sheet).

Final drying time
At + 20°C and good ventilation final curing is achieved after approx. 8 - 10 days.
Curing also takes place at lower temperatures – below + 10°C – but it takes longer.
Curing also takes place under water.

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

Concrete:
Solid and gripping, free of cement laitance, dust, loose and friable particles and other contamination. Concrete moisture content max. 8 %. Sweep blasting increases adhesion. This is particularly important in case of underwater exposure. Large holes, holidays and cavities etc. should be levelled up with e.g. Icoment®-520 Mortar or Sika Poxitar® SW Mortar.

Steel:
Blast-cleaning to Sa 2 ½ according to ISO 12944-4.
Free from dirt, oil and grease.
Average roughness depth R_Z ≥ 50 microns

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

Airless-spraying:

• Pressure min. 150 bar
• Diameter of hoses min. 10 mm (⅜ inch)
• Nozzle size 0.53 - 0.66 mm (0.021 - 0.026 inch)
• Spraying angle 40° - 80°
