This best metal silane agent for steel has a wide range of applications: This product is mainly used as a protective agent for concrete materials such as stations, airports, docks, bridges, and tunnels.
The metal silylation process is an alternative process to phosphating that emerged as the times require. It utilizes the amphiphilic properties of silane (i.e., organic and inorganic) to functionally replace the corrosion resistance of phosphating and improve coating adhesion. Ability. In the 1990s, the United States began to study silanization technology. Since silanization technology does not contain phosphorus and has superior environmental performance, it has always been a research hotspot in metal treatment. After nearly two decades of research, silanization technology has gradually matured, and because its cost is comparable to phosphating, it is regarded as the future of metal treatment processes.
Silanization treatment is a process of surface treatment of metal or non-metallic materials using organosilane as the main raw material. Compared with traditional phosphating, this best metal silane agent for steel has the following advantages: no harmful heavy metal ions, no phosphorus, and no need for heating. The silane treatment process does not produce sediment, the treatment time is short, and the control is simple. There are few processing steps, the surface adjustment process can be omitted, and the bath liquid can be reused. Effectively improve the adhesion of paint to the substrate. It can process a variety of substrates such as iron plates, galvanized plates, aluminum plates, etc. in line.
Due to the difference in film-forming principles, the operating temperature of this best metal silane agent for steel has been significantly reduced compared with phosphating, eliminating the need for surface conditioning procedures. And in other aspects involving production costs, silanization also has obvious advantages over phosphating.
The peelable width of iron-based phosphating is significantly different from that of zinc-based phosphating and silanization. Iron-based phosphating can peel off a large area, while the peelable width of zinc-based phosphating and silanized boards is basically zero. Therefore, it can be clearly seen that zinc-based phosphating and silanization treatments have equivalent adhesion to paint films, and at the same time, the adhesion of both is significantly better than iron-based phosphating. The effect of silanization treatment is equivalent to that of zinc-based phosphating in terms of salt water resistance and adhesion.
