Sikadur®-52 Normal

Low viscosity epoxy resin

Sikadur®-52 Normal is a low viscosity, free flowing and fast curing injection resin and primer/coating based on a 2 component solvent free epoxy resin; ideally suited to a wide range of building and civil engineering applications where highly penetrative material is required. 

  • Shrink free
  • Insensitive to moisture during application, cure or whilst in service
  • Applicable over wide temperature range
  • Low viscosity
  • Excellent adhesion to most building materials even when damp
  • High tensile and flexural strength
  • Supplied in factory proportioned units
  • High early strength
  • Chemical resistant

Usage

Sikadur®-52 Normal may be used to inject and fill cracks between 0.2 - 5 mm wide in a wide variety of constructions applications. Sikadur®-52 Normal does not shrink on curing and forms a rigid, high strength product which exhibits excellent adhesion to most construction materials enabling the restoration of structural adequacy to columns, beams, foundations, decks and water retaining structures. Due to its highly penetrative nature Sikadur®-52 Normal is ideally suited for application as a primer beneath Sikadur epoxy mortars or Sikafloor mortars and coatings on dense substrates. Sikadur®-52 Normal may also be used to stabilise weak and friable substrates.

Application steps

SUBSTRATE PREPARATION

All surfaces to be coated, should be mechanically roughened, free from all contaminants (eg. dust, oil, grease, etc.) surface water, laitance, old coatings, corrosion products. Suitable methods of preparation include blast cleaning and scabbling. For optimum penetration the substrate should be dry.
When Sikadur®-52 Normal is used to inject cracks, the cracks must be blown out with oil free, dry compressed air. Cracks in the width range of 0.2 - 5 mm may be successfully injected.

MIXING

Sikadur®-52 Normal is supplied in factory proportioned units comprising the correct quantities of Part A (Resin) and Part B (Hardener). Thoroughly stir both components separately using a slow running drill with a windmill type paddle (max. speed 600 rpm). Decant all of Part B into Part A and mix thoroughly (typically 3 mins). (Not applicable to twin cartridge packs).

CLEANING OF TOOLS

Uncured material may be cleaned from application tools, etc. by using Sika Thinner C (flammable solvent). Cured material can only be removed mechanically.
