SikaCor®-950 F

2 years

In originally sealed containers in a cool and dry environment.

~1.9 kg/l

~75 % by volume
~88 % by weight

Resistant to freshwater, process water, brackish water, seawater, domestic sewage, faeces, diluted inorganic acids and lyes, neutral salts, mineral and fuel oils, grease, detergents, etc.
Industrial wastewater upon request, based on wastewater analysis.
Not resistant to exposure to benzene-hydrocarbons and tar oil.

Dry heat up to approximately +100°C
Warm water up to approximately +60°C
NOTE: Not resistant to warm water at significant differential of temperature gradient!

Minimum +10°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 and possibly little alligatoring may occur. However, this will not affect the quality.

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

NOTE: 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 de-dusting / cleaning is necessary.

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

Drying Time at +20°C:
Dry to touch after ~4 hours, dry to handle after ~12 hours.

Final Drying Time:
At +20°C and good ventilation, final curing is achieved after approximately 7 days.
Curing also takes place at lower temperatures (i.e. below +10°C), but takes longer.

Minimum +10°C

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

Concrete:
Shall be solid in nature with a gripping surface, free of cement laitance, dust, loose and friable particles and other contamination. Concrete moisture content to be maximum 6%. Sweep blasting increases adhesion. This is particularly important in the case of underwater exposure. 

Stir component A thoroughly using an electric mixer (start slowly, then increase up to approximately 300 rpm). Add component B carefully and mix both components thoroughly (including sides and bottom of the container). Mix for at least 3 minutes until a homogeneous mixture is achieved. Fill mixed material into a clean container and mix again as described above. During mixing and handling of the materials, always wear protective goggles/glasses/faceshield, suitable gloves and other necessary personal protective equipment.

The method of application has a major impact on achieving uniform thickness and appearance. Spray application will obtain 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.
