- SHENYANG
Silane treatment technology is a relatively mature new nano-scale metal pretreatment technology at present. It replaces the traditional iron-based and zinc-based phosphating products.silane surface treatment agent for GI does not contain harmful heavy metal ions such as nickel, zinc, and manganese, and will not pollute the environment;
There is no slag in the silane treatment process, the treatment time is short, the control is simple, and the maintenance is simple; silane treatment agent pre-coating for GI can also treat a variety of metal substrates such as cold-rolled steel, aluminum, galvanized steel, and coated plates in line, providing them with superior anti-corrosion properties.
surface pretreatment agent for GI, as the agent pre-coating is gradually replacing the original pretreatment process with its excellent environmental protection and energy-saving performance.
Second, the chemical principle of silane treatment
The product is based on polymers with organosilane functional groups, which can provide us with the required anti-corrosion and enhanced coating adhesion requirements.

The black spot defects on the surface of non-oriented silicon steel are mainly randomly distributed on the lower surface of steel plate without a specific period and in an irregular distribution. The main reason for the formation of black spot defects is that the coating liquid splashes on the surface of steel plate, causing the local coating to be too thick. After drying and sintering, black spot defects are formed on the product surface
