Sikadur®-52
Sikadur®-52 is a two component system, based on high resistance epoxy resin, free of solvents.
- Does not contain solvents.
- It can be applied on dry or wet surfaces.
- Usable at low temperatures.
- Hardening without retraction.
- High adhesion and mechanical resistance.
- High non-brittle hardness.
- Low viscosity Injectable with one-component systems.
Usage
As an injection resin with good adhesion to concrete, mortar, stone, steel and wood. Sikadur®-52 is used to fill and seal cracks and pores in structures such as buildings, bridges, industrial facilities and other structures, for example, in columns, beams, foundations, walls, pavements and water ponds. Sikadur®-52 structurally joins the concrete sections and forms an effective barrier against the infiltration of water and corrosive elements.Advantages

Consumption
The consumption of Sikadur®-52 depends on the width and depth of the cracks, for 1 liter of filling, 1.1 kg of Sikadur®-52 is required.
NOTES ON INSTALLATION
Maximum crack width to be injected: 5mm.
Sikadur® 52 is suitable for dry and wet conditions but not for conditions with free water.
SUBSTRATE PREPARATION
Requirements Healthy, clean, free of oil or grease, without surface treatment or coatings.
Previous treatment for good adherence:
Concrete, mortar, stone must be carefully prepared by means of high pressure water jet or mechanical means such as roughing, etc. Cracks must be cleaned to remove dust with pressurized air.
MIXING
Mixing ratio A: B = 2: 1 (by weight); A: B = 1.8: 1 (by volume).
Add all component B to part A. Mix with an electric mixer at low speed (max. 250 rpm) for at least 3 minutes. Avoid incorporating air.
CLEANING OF TOOLS
Tools and instruments must be cleaned after use with pyroxylin thinner. The hardened product can only be removed mechanically.
