GENIOSIL® IBTE CE is iso-Butyltriethoxysilane.
GENIOSIL® IBTE CE is used in undiluted form for the hydrophobic priming and impregnation of concrete and reinforced concrete.
In addition GENIOSIL® IBTE CE is suitable for the hydrophobic treatment of fillers and pigments.

特性
GENIOSIL® IBTE CE
is characterised by:
- Excellent penetrating power
- solvent free, environmentally compatible
- low volatility
Treated concrete will have the following permanent properties:
- dramatic reduction in water and water diluted salt absorption (e.g.: chlorides and sulfates)
- high level of breathability
- improved durability against freeze-thaw de-icing salt stress
- enhanced durability
- provides good adhesion for paints
In the construction material GENIOSIL® IBTE CE
reacts with atmospheric moisture and / or the water in the building material’s pores, eliminating alcohol. The active thus substance formed greatly reduces the concrete’s absorbency in the active zone (penetration depth after post treatment), but without blocking any pores or capillaries. The impregnated building material retains very high water-vapor permeability.
数据表
The work performed (preparing the concrete surface, setting up a reference surface, application and quality control) must follow the applicable regulations (in Germany these are the DAfStb repair work guidelines and the ZTV-ING).
- Concrete should not be treated until at least four weeks after it has been produced so that the setting of the cement is not affected.
- New surfaces that are still unsoiled must be cleansed of coarse particles and dust deposits by sweeping or, if necessary, using compressed air. Surfaces already weathered, and those heavily soiled by oil, rubber residue, etc., must first be cleaned using superheated steam or high-pressure water before commencing treatment. It is imperative that the water used be siphoned off immediately to prevent saturation of the concrete.
- Hydrophobic Impregnation should always be performed on superficially dry concrete, i.e., when the surface of the concrete appears evenly dry, no more damp patches are visible and the moisture content equilibrium is established. To this end, moisture in the surface zone of the concrete is measured using a suitable technique (CM method or other methods allowed under ZTV-ING). The surface-zone moisture content of the concrete (from the surface to a depth of 20 mm) should not exceed 4 wt%.
- Evenly apply the hydrophobic impregnating agent to the building material in several coats, wet-on-wet. Do not allow puddles to form. The impregnating agent is applied by flow coating at reduced pressure. A lambskin roller may be used afterward for more even coverage.
- In the event of unexpected rain, cover surfaces already impregnated and halt all further impregnation.
- GENIOSIL® IBTE CE should never come in direct contact with bitumen. The resistance of insulating materials to GENIOSIL® IBTE CE must be tested on a case-by-case basis for the required temperatures.
GENIOSIL® IBTE CE is recommended for the hydrophobic impregnation and priming of concrete and reinforced concrete in road, bridge and building construction. In addition it is suitable for the hydrophobic treatment of fillers and pigments.

储存
The containers must be protected against sunlight. The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
