Sikadur®-30

Thixotropic self-priming epoxy adhesive for structural strengthening using CFRP laminates and steel plate bonding

Sikadur®-30 is a thixotropic, structural 2-component adhesive, based on a combination of epoxy resins and special filler, designed for use at normal temperatures between +8 °C and +35 °C.

Sikadur®-30 has the following advantages:
  • Very low VOC
  • Easy to mix and apply.
  • No primer needed. Self Priming adhesive saving time on installation.
  • 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.

Application

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

Material 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 mat damp concrete, brush the adhesive well into the substrate.

Pot Life

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).
Application steps

SUBSTRATE QUALITY

See the Product Data Sheet of Sika® CarboDur® Plates and Sika® CarboDur® BC rods.

 

SUBSTRATE PREPARATION

See 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.

MIXING

Pre-batched units:
Mix componentss A+B together for at least 3 minutes with a mixing spindle attached to a slow speed electric drill (max. 300 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.
Bulk packing, not pre-batched:
First, stir each component thoroughly. Add the components in the correct proportions into a suitable mixing pail and stir correctly using an electric low speed mixer as above for pre-batched units.

CLEANING OF EQUIPMENT

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