SikaFlow®-400

Epoxy resin with selected aggregates

12 months from the date of production.

Stored properly in air-conditioned enviroment in original, unopened, sealed and undamaged packaging in dry conditions at temperatures between +5 °C and +30 °C. Protect from direct sunlight, heat and moisture.

~1.93 kg/l (mixed, +25 °C)

Minimum grout depth: 20 mm
Maximum grout depth: 80 mm

+20 °C min. / +40 °C max.

Substrate temperature during application must be at least 3 °C above dew point to avoid condensation.

+15 °C min. / +40 °C max.

≤ 4 % 

Mortar and concrete must be older than 28 days (dependent on minimum strength requirements). Verify the substrate strength (concrete, natural stone etc.).

The substrate surface (all types) must be clean, dry and free from contaminants such as dirt, oil, grease, existing surface treatments and coatings etc. Steel substrates must be de-rusted to a standard equivalent to Sa 2.5.

The substrate must be sound and all loose particles must be removed. Substrate must be dry or mat damp and free from any standing water, ice etc.

Concrete, mortar, stone
Substrates must be sound, dry, clean and free from laitance, ice, standing water, grease, oils, old surface treatments or coatings and all loose or friable particles must be removed to achieve a laitance and contaminant free, open textured surface.

Steel
Must be cleaned and prepared thoroughly to an acceptable quality standard equivalent to SA 2.5 i.e. by blastcleaning and vacuum. Avoid dew point conditions.

Surface and base plate contact area must be clean and sound. For best results, the substrate shall be dry. Remove dust, laitance, oils, grease, curing compounds, impregnations, waxes, foreign particles, coatings, and disintegrated materials by mechanical means, i.e. chipping with a chisel, blastcleaning etc.

All anchor pockets or sleeves must be free of water.
Apply grout immediately to prevent re-oxidizing / rust formation.

For optimum results:
When grouting areas or equipment that is sensitive to vibration, it is recommended that the contact surfaces are prepared according to the latest edition of the American Petroleum Institute’s Recommended Practice 686 “Machinery Installation and Installation Design”, Chapter 5.

Mix components A and B for approximately 30 – 60 seconds with a paddle attached to a low speed drill (300 – 450 rpm). Avoid aeration while mixing until the material becomes uniformly blended in colour and viscosity. Place the mixed epoxy into an appropriate mixing vessel. Slowly add the contents of component C (to keep air entrapment at a minimum), mix until uniform and homogeneous (approximately 3 minutes).
Mix only that quantity which can be used within its potlife.

Never mix component A and B without adding component C (as the exothermic reaction between A and B alone generates excess heat)
Leave SikaFlow®-400 to stand in the normal mixing vessel until the majority of entrained air bubbles have dispersed.

Sweep excess grout into appropriate containers for disposal before it has hardened.
Dispose of in accordance with applicable local regulations. Uncured material can be removed with suitable thinner (Xylene / MEK / Acetone). Cured material can only be removed mechanically.
