Why Dacromet coating can't be placed in high temperature environment?

Posted on 2019-03-11
Dacromet equipment plays an important role in modern industry. Dacromet coatings are also very common in production, but Dacromet coatings cannot be stored at high temperatures. Why?
The reason is that there are a series of advantages in Dacromet technology that traditional plating can't match, which is quickly pushed into the international market. After more than 20 years of continuous development and improvement, Dacromet technology has now formed a complete surface treatment system, which is widely used in the anti-corrosion treatment of metal parts. This company established Nippon.Darro.shamrock (NDS) in 1973 with Japan Oil & Fats Co., Ltd., and also established DACKAL in Europe and France in 1976. They divided the world market into four major markets: Asia Pacific, Europe, Africa and the Americas. Responsible for one region and seek common interests on a global scale.
Because that the higher temperature, the more likely the aging of the coating liquid is, the storage temperature of the Dacromet coating liquid is preferably controlled below 10 °C. At the same time, under the sunlight, the coating liquid is easy to polymerize, metamorphose, and even scrapped, so it is best to keep it in a cool place. The storage period of Dacromet coating liquid is not very long, because the longer the stored coating liquid, the higher the pH value will be, which will cause the coating liquid to be aged and discarded. Some experiments have shown that the waste after the preparation of chromium-free Dacromet ,the liquid is valid for 30 days at 20 ° C, 12 days at 30 ° C, and only 5 days at 40 ° C.
Therefore, the Dacromet coating liquid must be present under low temperature conditions, or the high temperature will cause the coating liquid to age.
