When using multiple units one after the other, do not mix the following unit until the previous one has been used in order to avoid a reduction in handling time.
Product Temperature
Sikadur®-42 IN must be applied at temperatures between +15 °C and +35 °C. Condition the material by also storing at this temperature for 48 hours before use.
Ambient Air Temperature
+10 °C min. / +35 °C max.
Dew Point
Substrate temperature during application must be at least 3 °C above dew point to avoid condensation.
Substrate Temperature
+10 °C min. / +35 °C max.
Substrate Moisture Content
≤ 4% pbw
Pot Life
~15 minutes (+30 °C, 100 g mass) | (FIP 5.1) |
The pot life begins when the resin and hardener are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the pot life. To obtain longer workability at high temperatures, the mixed adhesive may be divided into portions. Another method is to chill parts A+B and C before mixing them (i.e. only when application temperatures are above +20°C).
Consumption
~2000 kg/m3
SUBSTRATE QUALITY
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.
SUBSTRATE PREPARATION
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 blast cleaning 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, blast cleaning 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.
MIXING
Pre-batched units:
Mix components A and B in the component A pail for approx. 30–60 seconds with a paddle type mixer 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) dependent on flow requirements (observe the correct mixing ratio) and mix until uniform and homogeneous (approx. 3 min). Mix only that quantity which can be used within its pot life.
CLEANING OF TOOLS
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 Sika® Colma Cleaner. Cured material can only be removed mechanically.
