The rapid development of the automotive industry cathodic electrophoresis coatings industry has long benefited.

In recent years, China's automobile industry has developed rapidly. Data show that in the first 11 months of this year, car production reached 2.527 million units, up 14.26% year-on-year and a new record high. Cathodic electrophoresis
coating
has good corrosion resistance, has replaced anode electrophoresis paint as a car base coating. The rapid development of the automotive industry will stimulate the growth of the cathodic electrophoresis coatings industry.
Unlike general coatings, electrophoresis coatings have two main characteristics, one is water as a solvent, non-toxic, non-polluting, no fire danger;
According to the "China Cathodic Electrophoresis Coatings Industry Investment Planning Analysis Report" data released by the Forward-Looking Industry Research Institute, more than 90% of the world's automobiles produce mid-bottom coatings using electrophoresis coatings, of which cathodic electrophoresis coatings account for 90%. Cathodic electrophoresis coatings almost completely replace anode electrophoresis coatings because they avoid defects that reduce corrosion resistance due to the involvement of coatings in electrolytic reactions.
cathode electrophoresis coating consists of a cation-type resin and other components, the United States PPG company in 1972 successfully developed. After more than 20 years of development, cathodic electrophoresis coating level has been greatly improved, the variety is also increasing.
Simply put, the development trend of cathodic electrophoresis coating is mainly manifested in four aspects, namely, the thickness of the coating film from thin to thick, swimming permeability from low to high, organic solvent content from high to low, curing temperature from high to low.
China's development and application of cathodic electrophoresis coating and coating technology history of up to 20 years, the earliest in 1979 by the Ministry of Weapons May 4 Research Institute developed the first generation of cathodic electrophoresis paint. However, China's independent research and development of cathodic electrophoresis coatings and foreign products have a certain gap, the advantages are mainly in terms of price.
cathodic electrophoresis coatings are developed by the automotive industry, so the current cathodic electrophoresis coating industry trend is to meet the increasing requirements of automotive coating lines. Such as thick-film cathode electrophoresis coatings, low-temperature cured cathode electrophoresis coatings, etc., are designed to adapt to the requirements of higher automotive components.
, in order to expand the use of cathodic electrophoresis coatings, foreign enterprises began to pay attention to high decorative cathodic electrophoresis coatings. However, high decorative cathodic electrophoresis coating is still in the research and development stage, there is no mature products. Because there must be good corrosion resistance, but also to highlight decorative, technical difficulty.
, as the automotive industry continues to develop at a high speed, the cathodic electrophoresis coatings industry will continue to benefit, and continue to introduce new products to meet the increasing requirements of the automotive industry. China still has a lot of room for improvement in this regard, although it can not reach the level of foreign technology, but there is a clear price advantage, the future is expected to occupy a certain market share.
