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).
Advantages
Sikadur-30 has the following advantages:
  • Easy to mix and apply.
  • No primer needed.

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).
