| Sikadur-30 is a thixotropic, structural 2-component adhesive, based on a combination of epoxy resins and special fillers, designed for use at normal temperatures between +8 °C and +35 °C. - Easy to mix and apply.
- No primer needed.
- High creep resistance under permanent load.
- Very good adhesion to concrete, masonry, stonework, steel, cast iron, aluminium, timber and Sika CarboDur Plates.
- Hardening is not affected by high humidity.
- High strength adhesive.
- Thixotropic: non-sag in vertical and overhead applications.
- Hardens without shrinkage.
- Different coloured components (for mixing control).
- High initial and ultimate mechanical resistance.
- High abrasion and shock resistance.
- Impermeable to liquids and water vapour.

Usage Adhesive for bonding structural reinforcement, particularly in structural strengthening works. Especially for the following uses: - Sika CarboDur Plates to concrete, brickwork and timber (for details see the Sika CarboDur Product Data Sheet, the “Method Statement for Sika CarboDur Externally Bonded Reinforcement” Ref: 850 41 05 and the “Method Statement for Sika CarboDur Near Surface Mounted Reinforcement” Ref: 850 41 07).
- Steel plates to concrete (for details see the relevant Sika Technical information).

Application Information Mixing Ratio Component A : Component B = 3 : 1 by weight or volume
When using bulk material the exact mixing ratio must be safeguarded by accurately weighing and dosing each component. Layer Thickness 30 mm max. Sag Flow On vertical surfaces it is non-sag up to 3−5 mm thickness at 35 °C | (FIP: Fédération Internationale de la Précontrainte) |
Squeezability 4’000 mm2 at +15 °C at 15 kg | (FIP: Fédération Internationale de la Précontrainte) |
Product Temperature Sikadur-30 must be applied at temperatures between +8 °C and +35 °C. Ambient Air Temperature +8 °C min. / +35 °C max. Dew Point Beware of condensation.
Substrate temperature during application must be at least 3 °C above dew point. Substrate Temperature +8 °C min. / +35 °C max. Substrate Moisture Content Max. 4 % pbw
When applied to matt damp concrete, brush the adhesive well into the substrate. Pot Life | Temperature | Potlife | Open time | | +8 °C | ~120 minutes | ~150 minutes | | +20 °C | ~90 minutes | ~110 minutes | | +35 °C | ~20 minutes | ~50 minutes |
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 components A+B before mixing them (although not below +5 °C). |
