Silane Impregnating Agent

Usage

Silane impregnating agent is a chemical compound used to enhance the properties of various materials, such as concrete, wood, and textiles. It is primarily used as a waterproofing and surface protection agent, providing improved durability and resistance against moisture, chemicals, and weathering. Silane impregnating agents penetrate deeply into the material's structure, forming a strong bond and creating a protective barrier.

They are particularly suitable for the protection of various concrete structuresthat are subject to seawater corrosion, salt fog corrosion, deicing agent corrosion, and freeze-thaw damage.

Advantage

Product advantages include: Deep penetration ability, Reduction of chloride ion diffusion, UV resistance

We have four types products main contain as Isooctyltriethoxysilane, Isobutyltriethoxysilane,  n-Octyltriethoxysilane and n-Butyltriethoxysilane.

Construction Technology：

1. To ensure the effect of Silane impregnating agent, new construction projects should be constructed after the concrete components have beencured for 2 to 4 weeks, and repair projects should be constructed after 1 to 2 weeks of curing. lf the ambient temperature is lower than 5'C, orhigher than 40°C, or the wind speed is greater than level 6, construction should be stopped to reduce material loss.

2. Before construction,repair the concrete structure defects, use a wire brush, compressed air and fresh water to clean the surface dust, sewage.
oil and other pollutants, and keep the surface dry for more than 3 days.

3. Before large-scale silane impregnating agent , a spray test must be conducted first, and then core sampling and testing of the test area mustbe performed according to the prescribed method. Only when the test results meet the judgment criteria can the silane impregnating agent besprayed on a large area of the structure

4. Usage and dosage of Silane impregnating agent : When spraying liguid, spray continuously to make the surface saturated and overflow. Forhorizontal surface construction, spray or brush until the surface ofthe substrate is wet or miror-like. For verical surace, spray from the bottomto the top, with a vertical flow length of 15-20cm, so that the surface remains wet for a few minutes. Spray the liquid waterproofing agent twice.with a spraying amount of 300g/m each time, and leave an interval of 10 minutes.

5. Area construction, it is recommended to use airless spray equipment, which has high construction efficiency5.Construction equipment: For large.and can reduce the loss of raw materials; for smal-area construction, a brush or scraper can be used; ifit rains suddenly during construction,stop construction immediately and caretuly cover the constructed components to prevent the loss of slane active ingredients before curing dueto rain, which will affect the construction effect

6. Maintenance: After silane appication, ensure that it is not exposed to rain for at least 24 hours and dry naturaly, to ensure the ideal treatmenteffect, the surface should be kept dry for at least 36 hours in summer and at least 72 hours in winter.

7. The absorption process of the Silane impregnating agent solution willast for several hours. The absorption rate depends on environmentalconditions, such as the relative temperature of the air, the concrete mix ratio, the moisture content of the concrete, the exposure of the treatedsurface, sunlight and wind speed, etc. The concrete surface may temporarily turn black and it wi take a few days to restore its originalappearance.

Note: Slane paste is a non-fammable, non-corrosive, water-based product. Wear a mask, goggles and gloves during construction. f it comesinto contact with skin or eyes, rinse immediately with plenty of water. lf the situation is particularly serious, seek medical attention in a timelymanner.

Packaging and storage:

It is packaged in barrels, with the net weight of silane impregnating agent being 25kg/barrel; the net weight of silane paste being 10kg/barrel.

Under normal storage and transportation conditions, the storage period is 12 months.
