Sikadur®-43 HE (h)

3-part thixotropic epoxy patch repair / filling mortar

Sikadur®-43 HE (h) is a thixotropic, three part patch repair and filling and bonding mortar, based on a combination of epoxy resins and special fillers, designed for use at temperatures between +5°C and +40°C.

Sikadur®-43 HE (h) has the following advantages:
  • Easy to mix and apply
  • Suitable for dry and damp concrete surfaces
  • Very good adhesion to most construction materials
  • High strength
  • Thixotropic: non-sag in vertical and overhead applications
  • Cure under damp conditions - cured product is highly impermeable to water
  • Different coloured components (for mixing control)
  • No primer needed
  • High initial and ultimate mechanical strength
  • Good abrasion resistance
  • Good chemical resistance
  • Suitable for Industrial equipment and machinery subject to static or dynamic forces

Application

Application Information

Layer Thickness

50 mm max.

When using multiple units, one after the other. Do not mix the following unit until the previous one has been used in order to avoid a reduction in handling time.

Product Temperature

Sikadur®-43 HE (h) must be applied at temperatures between +5°C and +40°C.

Ambient Air Temperature

+5°C min. / +40°C max.

Substrate Temperature

+5°C min. / +40°C max.

Pot Life

415ml                                                              (According to ASTM D2471-99)

+ 300C

~35 minutes

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 and C before mixing them (not below +5°C).
Consumption

Consumption

The consumption of Sikadur®-43 HE (h) is ~ 2.2 kg/m2 per mm of thickness.
Application steps

SUBSTRATE QUALITY

Verify the substrate strength (concrete, masonry, natural stone).

The substrate surface (all types) must be clean and free from contaminants such as dirt, oil, grease, existing surface treatments and coatings etc.

Steel substrates must be de-rusted similar to Sa 2.5.

The substrate must be sound and all loose particles must be removed.

SUBSTRATE PREPARATION

Concrete, mortar, stone, bricks:

Substrates must be sound, clean and free from laitance, grease, oils, old surface treatments or coatings and all loose or friable particles must be removed to achieve a laitance and contaminant free, open textured surface.

Steel:

Must be cleaned and prepared thoroughly to an acceptable quality i.e. by blast cleaning and vacuum. Avoid dew point conditions.

Other surfaces (polyester, epoxy, glass, ceramic):

On these substrates pre-apply Sikadur®-31 and then, “wet on wet“ apply Sikadur®-43 HE (h)

MIXING

Part (A+B) : Part C = 1 : 4.8 (by volume)

CLEANING OF TOOLS

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