Sikagard®-706 Thixo

Silane based water repellent impregnation cream

Sikagard®-706 Thixo is a one-component reactive silane based impregnation cream.
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
  • Reduction of water absorption
 
  • Reduction of absorption of aggressive or deleterious agents dissolved in water (i.e. de-icing salts or chloride from marine environment)
  • No noticeable change of water vapour permeability
  • Not film forming
  • Ready for use
  • Long term efficiency, deep penetration
  • Increases the resistance of concrete to freeze and thaw cycles and de-icing salts
  • Resistant to sea water
  • Low VOC content

Usage

Sikagard®-706 Thixo is used as water-repellent impregnation (hydrophobic treatment) for absorbent substrates such as concrete in civil engineering or building concrete structures subjected to heavy stress due to freeze and thaw cycles and 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)

Application

Application Information

Ambient Air Temperature

+5 °C min. / +40 °C max.

Substrate Temperature

+5 °C min. / +35 °C max.

Substrate Moisture Content

<5-6% when measured with Tramex method

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.

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.
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 trial shall be carried out to assess the penetration depth in the substrate.
Application steps

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 automatically feed roller).

CLEANING OF TOOLS

Clean all tools and application equipment with Sika Thinner C immediately after use. Hardened / cured material can only be mechanically removed.
