VCI-707
VCI+
VCI-707 rust converter adopts the international advanced rust conversion technology. Relying on the composite organic acid groups grafted on the nano-polymer micelles, the rust is reduced to a passivation component with anti-rust ability. The polymer micelles are rearranged at the molecular level on the entire metal matrix, and the film layer will directly bond with the substrate through chemical bonds. Because the interface between the molecules will be rearranged so that there is almost no void between the particles, the film layer has high sealing, high rust removal performance, and high adhesion, so as to completely solve the problem of secondary rust after rust removal and before painting. It avoids the short-term secondary corrosion problem caused by incomplete rust removal.

The rust removal effect is even and thorough. Strong removal of impurities such as rust and oxide scale on the steel surface. Derusting and rust prevention are completed at one time, without secondary floating rust;
The steel parts after rust removal have certain rust resistance in ventilated and dry places;
Good corrosion inhibition effect on steel and iron;
Water-based product, free of heavy metal ions, no pollution to the environment
Rust converter is suitable for anti-corrosion treatment of iron and steel parts without oxides. Widely used in the manufacture and maintenance of steel structures, tunnels, bridges, urban construction facilities, highway facilities, pipelines, railway facilities, ships, wharf and port machinery facilities, petroleum facilities, metallurgy and chemical equipment, etc.
Rust converter can be used as a primer before painting Treatment; can also be used alone as anti-rust paint.
Comparison of the Effect
Comparison of the Effect
A:Rust converter can remove impurities such as rust and oxide scale on the surface of steel. The rust-removed steel parts have certain rust resistance in ventilated and dry places. Can be used as a primer before painting; it can also be used alone as a rust inhibitor.
A:Use brushes, roller brushes, spray guns and other tools to coat the surface of the steel workpiece or immerse the steel workpiece in the product. In about 1 minute, a yellow-green compound will be formed on the surface of the workpiece. After 15 to 20 minutes, the surface of the workpiece will dry and form a protective film. After 24 hours, the subsequent coating process can be performed.
If you want to make the final anti-corrosion coating, you can apply it 1-2 times at an interval of 30-60 minutes on the basis of one coating, so that the film layer is uniform, dense, bright, and has stronger anti-corrosion performance.
