Permeable silane impregnated coating is a kind of waterproof coating. It was developed in 1990s in China and was widely used in the concrete anti-corrosion construction of port and wharf. With the continuous development and application of silane, the application scope of silane has also evolved from the original port and wharf to the port engineering, traffic engineering, industrial facilities and civil buildings corrosion protection. Next, we will discuss and share some issues related to silane.


First of all, why can silane play the role of concrete anti-corrosion?


Concrete will be eroded by water and chloride ion in the open environment, which will affect the durability of the structure itself. In fact, water will cause a lot of structural diseases of concrete, which is the carrier of many diseases. Therefore, waterproof measures on the surface will play a great role in the anti-corrosion of concrete. Silane is a kind of penetrating impregnant with excellent performance. It has a small molecular structure. The capillary wall of deep penetrating concrete reacts with hydrated cement to form a polysiloxane interpenetrating network structure. Through a firm chemical bonding reaction, the micro structure of concrete surface is given a long-term hydrophobicity, and the function of breath and air permeability is maintained, thus greatly reducing the invasion of water and harmful chloride ions Ensure the concrete structure is free from corrosion.
