Sikagard®-706 Thixo

Thixotropic passive corrosion inhibitor/hydrophobic impregnation for reinforced concrete

Sikagard®-706 Thixo is a one-component reactive silane based impregnation cream (high viscosity). It is a solvent free product with ~80% content of active substance. Sikagard®-706 Thixo complies with the highest requirements of EN 1504-2 for hydrophobic Impregnation (penetration depth class II & resistance to freeze and thaw salt stresses).

  • Non-sag (thixotropic) consistency, allowing wastage-free application of sufficient quantities and assuring deep penetration.
  • Ready to use product for easy application.
  • Excellent and deep penetration.
  • Transparent after drying.
  • Mitigates corrosion rate of depassivated reinforcement bars.
  • Prevents chloride migration to reinforcement bars.
  • Reduces corrosion even in cracked concrete.
  • Effective against AAR (alkali aggregate reaction).
  • Can be used on new and corroding old structures.
  • Open to water vapour diffusion.
  • Increases electrical resistivity in concrete.
 
  • Increases the resistance of concrete to freeze and thaw cycles.
  • Resistant to sea water.
  • Low VOC content.
  • Complies with Dutch guidelines (RWS NEN-EN 1504-2) on CEM III.
  • Reduces capillary water absorption, protects against mist and splashing on vertical areas.
  • Reduction of absorption of aggressive or deleterious agents dissolved in water (i.e. de-icing salts or chloride from marine environment).
  • Long term durability.
  • Reduced green growth.

Usage

Sikagard®-706 Thixo is used as water-repellent passive corrosion inhibitor (with hydrophobic characteristics) for absorbent, non watercontacted concrete in civil engineering structures or buildings subjected to heavy exposure to freeze/thaw cycles, carbonation, de-icing salts or chloride attack in marine environment:
  • Suitable for protection against ingress (Principle 1, method 1.1 of EN 1504-9)
  • Suitable for moisture control (Principle 2, method 2.1 of EN 1504-9)
  • Suitable for increasing the resistivity (Principle 8, method 8.1 of EN 1504-9)

Waiting Time / Overcoating

Can be overcoated with water and solvent based polymer paint - contact the proposed paint manufacturer for recommendations. Sikagard®-706 Thixo can be used as water repellent primer under many Sikagard® protective coatings. Penetration of water is thus prevented at possible weak spots or in the event of damage to the top coat and the risk of consequential damages such as paint flaking can be reduced.

Waiting time: minimum 5 hours, maximum 1 week.
Consumption

Consumption

Dependent on substrate profile and porosity as well as the required penetration depth: 200–300 g/m2 per coat. Normally, 1 coat is enough – preliminary trials should be carried out to assess the penetration depth in the substrate.
Application steps

SUBSTRATE QUALITY

Substrates should be free of dust, dirt, oil, efflorescence and existing paint coats. Cracks in concrete more than 300 μm must be repaired prior to application of the hydrophobic treatment. Cleaning is best done with suitable detergents or by light blast cleaning, steam cleaning etc. Best results are obtained on dry, very absorbent substrates. The substrate must look dry, with no damp patches.

 

MIXING

Sikagard®-706 Thixo is supplied ready for use and should not be thinned or diluted.

APPLICATION

Sikagard®-706 Thixo is applied using airless spray, brush or long-hair roller (including automatic feed roller).

CURING TREATMENT

Sikagard®-706 Thixo does not require any special curing but must be protected from rain for at least 3 hours at +20 °C.

CLEANING OF TOOLS

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