Our company is easy to rust in the wet or harsh environment for the phosphating workpiece. By using the advanced technology formula at home and abroad, BY-73 rust inhibitor is used to compensate for the rust of phosphating. A major breakthrough is the ideal rust inhibitor for phosphating products.
There are many types of chemical conversion coatings of aluminum and its alloys, of which are typically chromate, phosphorous-chromate, tannic acid, and phosphate membranes. Among them, the chromate-phosphate film is relatively thick and has good corrosion resistance. In response to the market demand for aluminum products, the adhesion is strong, the corrosion resistance is good, and the cost is low. This product has been specially developed.
