Information

DACROMET is a translation and abbreviation of DACROMET, DACROMET rust, dikron. Zn-cr coating is a new anticorrosive coating with zinc powder, aluminum powder, chromic acid and deionized water as the main components.

Dacros was first created in the late 1950s. In North America, Scandinavia, the cold winter and thick ice on the road a serious impediment to the motion of the motor vehicle, people scattered on the ground with salt method to reduce the temperature of freezing point to ease the roads, but the chloride ion erosion of sodium chloride followed the steel substrate, transport damaged, serious problem appeared. American scientist Michael Martin was developed mainly metal zinc and aluminum, chromium acid and deionized water as solvent with high dispersion of water-soluble coating, coating on metal substrate, after full closed cycle coating baking, form a thin coating, dacromet coating resistance to chloride ion erosion successfully, anticorrosion technology has entered a new stage, It innovates the defect of short anticorrosion life of traditional process.

As a result, Dacro technology was adopted by the U.S. military as an anti-corrosion military technology (U.S. standard MTR-C-87115). In the 1970s, The Japanese NDS company introduced dacro technology from THE U.S. MCI Company, and bought out the rights to use it in the Asia-Pacific region and acquired a controlling stake in MCI. The island nation of Japan has a large tonnage of steel corrosion every year, so it pays special attention to anticorrosion technology. After the improvement of Dacro technology in Japan, more than 100 coating factories and more than 70 pharmaceutical units have been rapidly developed in Japan, and some developed countries have also introduced dacro technology. China officially dacro technology imported from Japan in 1994, initially only for the defense industry and domestic auto parts, and then develop to electric power, building, Marine engineering, household appliances, hardware and standard parts, railway, bridge, tunnel, highway guardrail, petrochemical industry, biological engineering, medical apparatus and instruments of powder metallurgy and other industries.
