Hydrophobic treatment

The deterioration of the durability performance of concrete structures significantly reduces their reliability and safety, greatly endangering their normal use. There are many factors that can cause the deterioration of concrete durability, among which steel corrosion is one of the main reasons for the decrease in concrete structure durability. Due to the corrosion of steel bars, a large number of concrete structures have to be repaired or dismantled in advance, resulting in huge economic losses. The hydrophobic treatment of CY-8831 and CY-8431 silane surfaces can reduce the probability and rate of steel bar corrosion caused by external chloride ion erosion of concrete, delay the start of steel bar corrosion, and reduce the quality loss rate of corroded steel bars.

Reasonable use of silane impregnation technology can achieve the following properties:

1. Superior waterproof performance, which can reduce the water absorption rate of concrete structures by more than 90%;

2. Waterproof coating materials that truly have "breathing function";

3. Not changing the original appearance of the building, suitable for projects with special requirements for the appearance of the building;

4. Excellent alkali resistance and durability, reducing maintenance frequency and cost;

5. Effectively suppress the phenomenon of darkening and mold growth on the surface of concrete structures caused by environmental corrosion such as acid rain and mold moss, which can maintain a good appearance of concrete structures for a long time.
