Isobutylene triethoxysilane {Consultation Sales Hotline}
Main Characteristics
The special small molecular structure of silane has good affinity with the concrete base material and can easily penetrate into the interior of the concrete. The active ingredient of silane is incompatible with the acid when exposed to it. It reacts chemically with the air in an alkaline environment and the moisture in the substrate to generate hydroxyl groups. These hydroxyl groups will cross-link and accumulate with the substrate and itself, and combine with the inner walls of the capillary pores, eventually forming a strong hydrophobic silicone network protective layer on the surface of the concrete capillary pores, which can effectively prevent external moisture and It can prevent the intrusion of harmful substances and allow internal water vapor and harmful gases to escape, thereby greatly improving the waterproofness, salt-alkali resistance, freeze-thaw resistance and other characteristics of the concrete structure, and extending the life of reinforced concrete to more than a year.
Excellent penetration depth
Only a small amount of coating is required to achieve excellent protection effect
Maintain the natural appearance of concrete
Significantly reduce the water absorption rate of concrete pores
Significantly reduces chloride ion erosion, freeze-thaw damage, steel corrosion and mold growth
Excellent chemical resistance, weather resistance, abrasion resistance, stain resistance, self-cleaning effect
Maintains the breathability of concrete
br/>Application examples
Widely used in various types of reinforced concrete structures, such as seaport terminals, cross-sea bridges, viaducts, highway bridges, coastal railway bridges, tunnels, airport runways, thermal power plants, nuclear power plants and other concrete structure protection .

Construction technology
Construction can be carried out with a sealing spray gun, roller or brush. If a brush or roller is used, the application should be repeated until the surface is moist. If a sealed spray gun is used, the spray equipment should be a continuously circulating pumping system with a nozzle pressure of ~ and water must not enter any part of the system.
The concrete base should be solid and smooth. If there are defects such as honeycombing, pitting, cracking, and looseness, they should be repaired in advance. The base layer should be cleaned to remove accumulated water, stains, oil stains, gray scale, scum, etc. To maximize penetration into the base, construction should be done on a dry surface.
When concrete uses a release agent or curing agent, the impact of the release agent or curing agent on silane impregnation should be determined through spraying tests in accordance with relevant regulations. Otherwise, it should be fully removed before silane impregnation
It is best to construct on a dry concrete surface. When constructing in a water level changing area, it should be constructed when the water reaches the lowest level and no water can be seen on the concrete surface, and a drying period of one hour can be ensured so that the silane can be absorbed by the concrete. No construction is allowed when it rains or there are strong winds or strong direct sunlight
. Construction should be carried out continuously, one time or in two times. The dosage should be at least 100% of the time between two times.
Notes
Precautions
The silane impregnating agent can be unsealed before use, and should be used up after being unsealed, otherwise it should be discarded.
Concrete should be constructed after the curing period (days) is over. During construction, the surface temperature of the concrete should be at ℃.
This product is flammable and will produce ethanol after curing. Safety precautions should be taken. Keep the construction site well ventilated and keep away from sparks, heat sources and open flames.
Operators should use necessary safety protection facilities.
Most of the silane will be completely absorbed by the concrete within about a few hours after construction. The concrete that has been impregnated with silane before this should avoid contact with water, and it will take several weeks for the complete reaction of silane and concrete to form a silicone network. time, so the experiment to test the silane effect should be carried out two weeks or longer after construction.
