Sikadur®-32 IN
Epoxy resin bonding agent
Sikadur®-32 IN is a solvent-free, two component bonding agent, based on selected epoxy resins.
- Easy to mix and apply
- Solvent free
- Unaffected by moisture
- Highly effective even on damp surface
- Workable at low temperatures
- High tensile strength
Usage
Sikadur®-32 IN provides a bond of far greater strength than the tensile strength of the concrete itself. Therefore it is suitable for use as a structural bonding agent for :- New to existing concrete
- Mortar
- Steel, Iron
Advantages

Application
Mixing Ratio
Part A : Part B = 2 : 1 (by weight)
Product Temperature
+10°C min / +40°C max.
Ambient Air Temperature
+25°C min. / +40°C max
Substrate Temperature
+25°C min. / +40°C max
Substrate Moisture Content
When applied to mat moisture concrete, brush the adhesive well into substrate.
Pot Life
55 minutes (100 g mass at +27 C) | (FIP 5.1 |
The potlife 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 potlife. To obtain longer workability at high temperatures, the mixed adhesive may be divided into portions. Another method is to chill parts A+B before mixing them (not below +5°C).
Open Time
55 minutes (100 g mass at +30°C) | (FIP 5.2) |
Consumption
0.3 - 0.8 kg/m2, depending on substrate condition
SUBSTRATE QUALITY
Mortar and concrete must be older than 28 days (dependent on environment and strength).
Verify the substrate strength (concrete, mortar).
The substrate surface (concrete, mortar) must be clean and free from frost standing water.
Steel substrate must be de-rusted similar to Sa 2.5.
Concrete substrate must be sound and all loose particles must be removed.
SUBSTRATE PREPARATION
Concrete, mortar
Substrates must be sound, dry, clean and free from laitance, ice, standing water, grease, oils, old surface treatments or coatings and all loosely adhering particles to achieve a laitance and contaminant free, open textured surface. Cement laitance must be removed and the surface to be treated must be mechanically roughened.
Steel
Must be cleaned and prepared thoroughly to an acceptable quality i.e. by blastcleaning and vacuum.
MIXING
Mix parts A+B together for at least 3 minutes with a mixing spindle attached to a slow speed electric drill (max. 600 rpm) until the material becomes smooth in consistency and a uniform grey colour. Avoid aeration while mixing. Then, pour the whole mix into a clean container and stir again for approx. 1 more minute at low speed to keep air entrapment at a minimum. Mix only that quantity which can be used within its potlife.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened / cured material can only be mechanically removed.
