Sikagard 706 Thixo

Sikagard 706 Thixo - Silane Based Impregnation Cream

Water-Repellent Hydrophobic Treatment for Concrete

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

Uses:

Sikagard-706 Thixo is used as a 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
• Chloride attack in marine environments

It is suitable for:

• Protection against ingress (Principle 1, method 1.1 of EN 1504-9)
• Moisture control (Principle 2, method 2.1 of EN 1504-9)
• Increasing the resistivity (Principle 8, method 8.1 of EN 1504-9)

Characteristics and Advantages:

• Non-sag (thixotropic) consistency for wastage-free application and 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.

• Drying rate coefficient (EN 13579): >30% (Class I)

System Information:

System structure: 1–2 coats of Sikagard-706 Thixo

Application Information:

• 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.
• 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 to 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. Waiting time: minimum 5 hours, maximum 1 week.

Application Instructions:

Substrate Quality / Pre-treatment: Free of dust, dirt, oil, efflorescence and existing paint coats. Cracks > 300 μm must be repaired. Clean with detergents or light blastcleaning, steam cleaning etc. Best results on dry, very absorbent substrates.

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

Application: Apply using airless spray, brush or long-hair roller (including automatically feed roller).

Cleaning of Equipment: Clean all tools with Colma Cleaner immediately after use. Hardened / cured material can only be mechanically removed.

Colour Accuracy Disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.

Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
