Sikadur®-52 MY
Low viscosity injection resins
Sikadur®-52 MY is a two part, solvent free, low viscosity injection-liquids, based on high strength epoxy resins.
- Solvent free
- Suitable for both, dry and damp conditions
- Shrinkage free hardening
- High mechanical and adhesive strengths
- Hard but not brittle
- Low viscosity
- Injectable with single component pumps
Usage
As an injection resin with good adhesion to concrete, mortar, stone, steel and wood, Sikadur®-52 MY is used to fill and seal voids and cracks in structures such as bridges and other civil engineering buildings, industrial and residential buildings, e.g. columns, beams, foundations, walls, floors and water retaining structures. It not only forms an effective barrier against water infiltration and corrosion promoting media, but it also structurally bonds the concrete sections together.Advantages

SUBSTRATE QUALITY
The substrate must be sound, clean, free from oil and grease, old coatings, and surface treatments.
SUBSTRATE PREPARATION
Concrete, mortar, stone should be thoroughly prepared by high pressure water jetting (150-200 bar) or by mechanical means such as grinding, and chiselling. Cracks must be cleaned with compressed air to remove dust and loosely adhering materials.
MIXING
Add all of part B to part A. Mix with a paddle attached to an electric mixer at slow speed (max. 250 rpm) for at least 3 minutes. Mixing at faster speed and/or longer periods may entrapped air.
For part mix, weigh part A and B separately (2:1 by weight) before mixing.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Colma-Cleaner immediately after use. Hardened and/or cured material can only be mechanically removed.
FAQ
A 2-component polyurethane structural injection resin can be used to seal structural concrete cracks. Cracks may be dry, damp or wet, but free from standing water.
Alternatively, a 2-component solvent free, low viscosity epoxy injection resin can also be used to seal structural concrete cracks.
