In originally sealed containers in a cool and dry environment.

~ 2.8 kg/l

~65 % by volume

~89 % by weight

The fully cured material is resistant to weathering, water and mechanical wear.

Dry heat up to + 150°C, short term up to max. + 180°C
Damp heat up to + 60°C

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

Min. + 5°C

Min. 30 %, max. 98 %, surface temperature shall be at least 3 K above dew point.
The surface must be dry and free from ice.

Min. 0°C

Between primer coat and intermediate coat (at + 20°C):

Higher layer thicknesses, but also lower temperatures than specified, lead to longer drying times. The overcoating intervals can be delayed and may need to be determined on site.

In case of longer waiting times please contact us.

When SikaCor® Zinc PUR is to be overcoated after a waiting period or after exposure to weathering, all zinc corrosion products or other contaminations must be removed from the surface before the subsequent coating material is applied.

Final drying time
Depending on layer thickness and temperature final hardness is achieved within several days.

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

Apart from small areas the dry film thickness of 150 µm of SikaCor Zinc PUR should not be exceeded per application.

Steel:
Blast cleaning to Sa 2 ½ according to ISO 12944-4.

Free from dirt, oil and grease.

All materials are supplied ready for use; stir thoroughly prior to application.

Attention, risk of injuries! Container may be under pressure. Lid may come off unexpectedly. Prior to opening reduce pressure, e.g. by piercing the lid.

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
