Cathodic Electrodeposition Coating Market
Cathodic electrodeposition coating have many environmental benefits that makes it an environment friendly solution for metal finishers. The volatile organic compounds (VOCs) content in cathodic electrodeposition coating ranges from 0.1 pounds per gallon to 3.0 pounds per gallon, with most of the products containing below 1.0 pounds per gallon. Moreover, most of the cathodic electrodeposition coating products are water-based and are have low VOC. The epoxy and acrylic grades of cathodic electrodeposition coating are formulated to be hazardous air pollutants (HAPS) free. The biochemical oxygen demand (BOD/COD) levels in cathodic electrodeposition coating is low and the products have the capability to be run without any waste water to drain via closed loop rinsing.
A properly maintained cathodic electrodeposition coating system generates a minimal amount of solid waste. Moreover, these systems are clean systems and do not require disposable suits, respirators, and other protective gears for protection of workers from airborne hazards that are a daily concern for spray painters. Moreover, it reduces fire hazards as, most of the cathodic electrodeposition products are not considered ‘Red Label’ (substance is considered as flammable), as they are formulated from water-based materials. This simplifies shipping and storage of these products.
However, one of the drawbacks using cathodic electrodeposition coating include non-uniform coating i.e. part of the substrate, which is in proximity to the metal source displays higher thickness compared to the part, which is away from the source. However, this limitation can be reduced by using baths, where metal ions are in complex form.
The cathodic electrodeposition coats exhibits high level of protection against corrosion due to presence of aromatic polyurethane and urea type cross-linkers. However, coatings containing aromatic polyurethane cross linkers do not perform well in ultraviolet (UV) lights. Aromatic polyurethanes can cause yellowing of the coating itself as well as yellowing in subsequent layers. Moreover, during the baking process, a significant undesired side reaction produces aromatic polyamines. These undesired aromatic polyamines can inhibit curing of subsequent acid catalyzed topcoat layers and thus, can cause delamination of subsequent top layers after exposure to sunlight.
The global cathodic electrodeposition coating market was valued at US$ 2,408.5 million in 2018 and is expected to exhibit a CAGR of 3.3%, in terms of value over the forecast period (2019-2027), and is expected to reach US$ 3,016.8 million by 2027.

North America is expected to exhibit significant growth in the global cathodic electrodeposition market during the forecast period. This is owing to the established automotive industry, which is creating a stagnant demand for new coating technologies in the region. Cathodic electrodeposition coatings are used in automotive parts. Therefore, growth of the automotive industry is expected to fuel demand for cathodic electrodeposition coating and in turn, is expected to drive the market growth during the forecast period. For instance, according to the American Automotive Policy Council report on State of the U.S. Automotive Industry in 2018, the U.S. auto production raised from 5.6 million vehicles in 2009 to 11.3 million vehicles in 2017. Moreover, according to the same source, the three major players in the U.S. automotive industry such as FCA US, Ford, and General Motors manufactures and buy vehicles and their parts, and also conducts R&D in the U.S. than their competitors.

Cathodic electrodeposition coating is the most widely used coating process in automotive industry, as it provides a corrosion resistant base coat on automotive parts in a single-layer process. Growth of the automobile industry is expected to drive demand for cathodic electrodeposition coating process over the forecast period. For instance, according to the India Brand Equity Foundation, India became the fourth largest auto market in 2018 with sales increasing 8.3% year-on-year to 3.99 million units. According to the same source, domestic automobiles sales increased by 6.71% during 2013-2019 with 26.27 million vehicles sold in 2019
Major players operating in the global cathodic electrodeposition coating market include Kansai Paint Co., Ltd., Axalta Coating Systems, Kyoei Vietnam Co., ltd, Nippon Paint Holdings Ltd., PPG Industries, Inc., B.L Downey, Dornauer-Grillitsch GmbH, KAPCO Manufacturing Inc., BASF Coatings Gmbh, and DuPont de Nemours, Inc.
Electrodeposition coating is the most conventional coating process used in automobile industry. The two types of electrodeposition available include anodic and cathodic. In cathodic electrodeposition coating, the metal part is negatively charged while the paint to be coated is positively charged. The cathodic process helps in reducing the iron that can enter the paint film, which helps in offering high performance and excellent corrosion resistance. Hence, cathodic process is the most preferred electrodeposition process.
Market Dynamics
Moreover, growth of the automobile industry is expected to drive demand for paints and coatings from the industry, which is expected to drive demand for cathodic electrodeposition coating method over the forecast period. The increase in transportation and transit of consumer goods, people, and raw materials have boosted growth of the automobile industry. For instance, according to the China Association of Automobile Manufacturers (CAAM), in September 2019, the production and sales of commercial vehicles in China reached to 345,000 and 340,000 units, respectively, which showed an increase of 15.8% and 11.6% than that of last month, and up by 4% and 1.9% year on year.
Furthermore, according to the European Automobile Manufacturers Association (ACEA), in December 2019, commercial vehicle registrations increased by 5.7% across the European Union (EU). Moreover, according to the same source, in EU, demand for commercial vehicles increased by 2.5% in 2019, marking the seventh consecutive year of growth.
Furthermore, key players across the globe in the market are focusing on business expansion to gain strong foothold in the global market. For instance, in December 2019, BASF Coatings Gmbh started construction of a new facility to double its production capacity of automotive refinish coatings at its site in Jiangmen, Guangdong Province in South China. The plant is expected to start production in the first half of 2022.
