Metal coating is a layer of coating applied on the car, mainly to protect the inner parts and skin of the car. We all know that the driving environment of the car is very complicated. For different locations, the environment The composition of the acid rain is also different, some heavy industrial bases will have more serious pollution, and with the frequent occurrence of severe weather, acid rain also gradually appears in our lives, causing serious damage to some open-air buildings, and metal coating The emergence of just alleviated this problem.
1. Anticorrosion of heat-loaded parts. Some auto parts have high working temperature, and the surface protective layer of these parts is required to have good corrosion resistance at high temperature. The curing temperature of Dacromet coating is about 3 degrees, and the coating The chromic acid polymer does not contain crystal water, the coating is not easy to be damaged at high temperature, and shows a certain high humidity anti-corrosion performance.
2. Anticorrosion of fasteners. Dacromet coating is suitable for high-strength fasteners. In addition to high corrosion resistance, the friction factor is also an important indicator of fasteners.
To sum up, it is the application of metal coating on automobiles. Only by understanding these can it play a better role in the actual application in the future. Here I want to remind everyone that if you want to carry out metal coating Surface treatment, before that, the body should be cleaned to prevent some impurities from adhering and affecting the normal use of metal coating.
