Sikadur®-32 Normal

• Structural bonding agent tested according to EN 1504-4, provided with the CE-mark

Epoxy resin

24 months from date of production

Store in original, unopened, sealed and undamaged packaging in dry conditions at temperatures between +5 °C and +30 °C. Protect from direct sunlight.

 Compressive strength at 4 % elongation

*100% concrete failure

Hardens without shrinkage.

(thickness 10 mm)

Component A : component B = 2 : 1 by weight or volume

~ 1 mm max in one application.Multiple layers can be used to achieve required final thickness.Wait for each previous layer to harden before applying next layer.

Sikadur®-32 Normal must be applied at temperatures between +10 °C and +30 °C.

+10 °C min. / +30 °C max.

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

+10 °C min. / +30 °C max.

*200 g

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 components A+B before mixing them (not below +5 °C).

The consumption of Sikadur®-32 Normal is ~ 1.3 kg/m² per mm of thickness.

Hardened mortar and concrete must be older than 28 days (depending on any minimal strength requirements).
Verify the substrate strength by testing (concrete, masonry, natural stone).
The substrate surface (all types) must be clean, dry or mat damp (no standing water) and free from contaminants such as dirt, oil, grease, existing surface treatments and coatings etc.
Steel substrates must be de-rusted to a condition similar to Sa 2.5.
The substrate must be sound and all loose or friable particles must be removed.

Concrete, mortar, stone and brick
Concrete and other hardened mineral substrates must be prepared by suitable means such as high pressure water jetting and / or blast cleaning, in order to obtain surfaces that are sound, clean, dry or mat damp (no standing water) and free from any cement laitance, ice, grease, oils, old coatings or other surface treatments. Any loose or friable particles must also be removed to achieve a contaminant free and open textured surface.
Steel
Steel surfaces must be cleaned and prepared thoroughly to the acceptable quality standard equivalent to Sa 2.5 i.e. normally by blast cleaning and then removing any dust by vacuum. Avoid dew point conditions.

Pre batched units (A & B Components):
Mix components for at least 3 minutes with a suitable mixing spindle for the pack size. Spindle should be securely attached to a slow speed electric drill (max. 300 rpm). Mix until the material becomes a smooth consistency and a uniform grey colour. Avoid air entrapment at all times to a minimum while mixing. After 1st mix, pour this mix into a clean container and stir again for approximately 1 more minute. Do not part mix the pre batched units.When mixing large quantities of units,mix only the required quantity of units that can be used within their potlife.

Clean all tools and application equipment with Sika^® Thinner C immediately after use. Hardened / cured material can only be mechanically removed.
