This Silane agent for aluminum is a non-toxic and effective silanization treatment agent for aluminum alloy surfaces.
The silane added in the formula of this Silane agent for aluminum can improve the binding force of coatings and paints on the treated aluminum alloy surface; the titanium chelate added can improve the corrosion resistance of the aluminum alloy surface. This product has a short silanization treatment time for aluminum, which can effectively save surface treatment time.
Metal surface silanization treatment technology is an environmentally friendly treatment technology that has been rapidly developed in the field of metal corrosion protection in recent years and is expected to replace chromate. This technology is mainly based on the characteristics that the silane hydroxyl groups generated after the hydrolysis of silane molecules can react with the metal oxides on the metal surface and the characteristics that the silane molecules can condense themselves to form an inorganic/organic film layer. It is deposited on the metal through immersion or electrochemical-assisted deposition. A film layer with hydrophobic properties is prepared on the surface. This film not only protects the metal substrate, but also improves the adhesion between the metal and the coating.
Compared with traditional phosphating, this Silane agent for aluminum 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.
