Silane Siloxane Coating - 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-thaw cycles and chloride ion penetration) and NCHRP Report 244 Series II & IV.

• 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 vapor permeability.
• Not film forming.
• Ready to 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.
• Waste free.
• Non-vapor Barrier.

Usage

Sikagard®-706 Thixo is used as water-repellent impregnation (hydrophobic treatment) for absorbent substrates such as:

• Marine structures
• Pilings
• Piers
• Bridge decks
• Building facades

1-2 coats of Sikagard®-706 Thixo

Technical Information

Resistance to Alkalinity

<10%

Application

Application Information

Ambient Air Temperature

40 °F (5 °C) min. / 100 °F (40 °C) max.

Substrate Temperature

40 °F (5 °C) min. / 95 °F (35 °C) max.

Substrate Moisture Content

<6 % when measured with Tramex method

Waiting / Recoat Times

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 68 °F (20 °C).

Consumption

Coverage

Between ~200-250 sq.ft/gal. can be applied in one operation to vertical and sloped surfaces without loss of material. The exact amount depends on the absorbency of the substrate. At higher application rates, the impregnating agent might liquefy at the top of the concrete and it may start to run off. A second coat may be applied at any time but is usually unnecessary. A preliminary trial should be carried out to assess the penetration depth in the given 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 Colma Cleaner immediately after use. Hardened / cured material can only be mechanically removed.
