Sikadur®-52 LVMY
Very low viscosity injection resins
Sikadur®-52 LVMY is a two part, solvent free, very 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
- Very low viscosity
- Injectable with single component pumps
Usage
As an injection resin with good adhesion to concrete, mortar, stone, steel and wood. Sikadur®-52 LVMY 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
Sound, clean, free from oil and grease, old coatings and surface treatments, etc.
SUBSTRATE PREPARATION
Pre-treatment for good bond
Concrete, mortar, stone should be thoroughly prepared by high pressure water jetting or mechanical means such as grinding, chiselling, etc. Cracks must be cleaned to remove dust with compressed air.
MIXING
Add all of part B to part A. Mix with an electric mixer at slow speed (max. 250 rpm) for at least 3 minutes. Avoid entraining air.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Colma-Cleaner immediately after use. Hardened 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.
