Aluminum gray aluminum gray coating agent oxidant HF-641

HF-641 aluminum gray oxidant I. Application: aluminum and aluminum gray chemical oxidation, phosphate, coating treatment process HF-641 aluminum gray oxidant system under normal conditions of use, applicable to all types of aluminum, especially for die-cast aluminum pistons, aluminum radiators and other gray processing, the product room temperature operation, color effect, do not fade, post-processing aluminum surface to form a dense layer of pure gray, but also electrophoresis, spray, spray paint and other coating Process before supporting the use of products and enhance its coating layer binding, preventing the paint off plastic layer; widely used in the surface treatment of various types of hardware accessories, machinery and equipment, auto parts and other industries. Second, the product advantages: 1, the product room temperature operation, color fast, film compact and does not reveal not fade repeatedly wipe the base character; 2, the product is an alkaline solution, operational safety and environmental protection, improve the environment and lower overall processing costs . Third, the operation process: aluminum activation treatment after degreasing → washed clean → HF-641 aluminum gray washed clean oxidant → → drying or spray four operating conditions: Operation No. Item Remarks 1 HF-641 aluminum gray oxidizer 1 : 3-5 watered colored low solubility slow, high concentrations of color fast 2 Operating temperature Room temperature 3 3-10 min treatment time overall gray color time to use whichever method workpiece 4 using solution soak 5 Plastic tank, PP / PVC tank five, operation and maintenance: 1, before soaking the product, should first clean aluminum surface oil and washed clean after immersion in this product; if the surface oxide layer, the removal of the oxide layer should be degreasing 2, after a period of use, the active ingredient solution decreases, should be timely supplemented with HF-641 aluminum gray liquid oxidant maintain good bath, in case add this product; clean and after treatment, in order to avoid uneven color occurs supreme guide When the color is not good, it is recommended to replace all the bath, the product processing area of ??one kilogram of liquid can handle 3-4 meters; 3, the product is slightly alkaline solution, good labor protection, that is good to wear rubber gloves. VI, packaging and storage: 25 kg / barrel, store in a cool place for 2 years effective.
