Compared with some traditional electroplating process, Dacro has more advantages. For example, the products after the use of Dacro process, corrosion resistance is dozens of times of the traditional galvanized, through the salt spray test found that ordinary Dacro can reach 20 times of galvanized, and those long-term dacro test time will be longer, some parts in the nuclear industry using Dacro process, the service life can reach 30 years.

Dacro does not crack or fracture under tension and stress as other plating processes DO.

Crowe has good stability in high temperature environment, which is much higher than the traditional galvanized high temperature resistance.

The PRODUCT WITH THE DACRE PROCESS HAS VERY GOOD IMPACT RESISTANCE, SO THE DACRE PROCESS IS VERY SUITABLE FOR THOSE STRESSED parts, BECAUSE THE DACRE process has good permeability and can combine the surface coating with the product very well.

Unlike SOME TRADITIONAL ELECTROPLATING PROCESSES, DACRO IS LESS POLLUTING DURING PRODUCTION, SO SOME HIGHLY POLLUTING surface TREATMENTS ARE gradually being REPLACED BY DACRO.

Despite the many advantages of Darrow, there are also some disadvantages.

Some Dacro contains hexavalent chromium ion which is harmful to the body. After long-term contact, it will cause harm to the human body and have the risk of cancer. According to the relevant product standards, it is not allowed to contain this harmful substance.

The surface color of Dacro craft is only silver and white, which is relatively simple, so if other colors are needed, it must be post-processed again to obtain different colors.

The poor electrical conductivity of the dacro coating, as well as the long time and high energy consumption in the production process, also limit its range of use.

So what is the Dacro surface treatment process, what is the difference between this surface treatment process and other metal surface treatment process, what is the special role?

DACROMET is a transliteration of DACROmet, also known as DACROrust or DACROdragon, which is a new type of anti-corrosion coating on metal surfaces using aluminum, zinc and chromic acid as the main coating materials.

The matrix materials of DacRO are mainly steel and non-ferrous metals. After the coating liquid reacts with the metal matrix, a silver-gray anti-corrosion film will be formed on its surface, which can separate the matrix from the air and protect the workpiece.

Dacro is widely used in various industries, such as construction, hardware, fasteners, road engineering and petrochemicals.

Dacro has very strong anti-corrosion performance, which makes up for the defects of short time of traditional anti-corrosion, and pushes the anti-corrosion technology to a new level.
