• Tested and official approved primer for Sika® Unitherm® and Sika® Pyroplast® fire protection systems on steel.

2 years

In originally sealed containers in a cool and dry environment.

~1.4 kg/l

~45 % by volume

~66 % by weight

Upon request

Dry heat up to approx. + 120°C, short term up to + 150°C

Sika® Thinner E+B

If necessary max. 2 % Sika® Thinner E+B may be added to adapt the viscosity.

Min. + 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.

Min. + 10°C

Waiting time at + 20°C

Dry film thickness of 40 μm

Final drying time

Depending on film thickness and temperature full hardness is achieved within 1 week at + 20°C. Tests of the completed coating system should only be carried out after final curing.

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

Steel:

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

Free from dirt, oil and grease.

Hot dip galvanized steel, sprayed zinc:

Free of oil, grease and zinc salts.

In case of permanent exposure to submersion and condensation surfaces should be sweep blasted according to ISO 12944-4.

Stainless steel, aluminium:

Sweep-blasting according to ISO 12944-4 with non-metallic / non-ferrous abrasives.

For contaminated and weathered surfaces e.g. hot dip 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 or roller

Airless-spraying:

• Nozzle size ≥ 0.38 mm
