In the field of industrial surface treatment, electrophoretic coating has long become a standard process in industries such as automobile manufacturing, hardware and home appliances, construction machinery, and rail transit, relying on its core advantages of uniform coating, strong corrosion resistance, high utilization rate, and environmental friendliness. With the continuous tightening of national environmental protection policies, the accelerated transformation of manufacturing intelligence, and the iteration of downstream end-market demand, the entire electrophoresis industry is ushering in an all-round transformation in products, technologies, and production models.
In recent years, traditional old electrophoretic production lines with high pollution and high energy consumption have been gradually eliminated, and green and low-carbon development has become the main theme of the industry. Water-based electrophoretic paint and lead-free, cadmium-free environmentally friendly electrophoretic raw materials have been fully popularized. Low VOCs emissions, closed-loop wastewater recycling, and harmless treatment of waste residues have become rigid standards for enterprises to build factories and carry out technological transformation. In the past, small workshop-style factories that seized the market with low-cost and inferior raw materials are accelerating their exit under the dual pressure of environmental supervision and industry norms. The industry concentration has further increased, and the competitive advantage of formal large-scale enterprises has become increasingly obvious. Globally, strict environmental regulations such as the EU's New Pollutant Regulation (NPR) and China's Volatile Organic Compounds Comprehensive Control Plan have also forced enterprises to phase out solvent-based coatings and switch to water-based electrophoretic coatings, which has become a global industry consensus.
In addition to environmental upgrading, intelligence and automation are restructuring the production logic of the electrophoresis industry. Traditional electrophoretic production lines rely on manual temperature control, paint mixing, and loading and unloading, which not only have low efficiency and uneven coating quality, but also are prone to defects such as sagging, pinholes, and color difference due to human operation. Today, fully automatic electrophoretic production lines, intelligent temperature control systems, automatic ultrafiltration recovery equipment, and robotic loading and unloading have been gradually popularized, realizing the full-process automatic operation from pre-treatment, degreasing and phosphating, electrophoretic coating to curing and drying. Automated capillary electrophoresis technology has also been continuously optimized, further improving the efficiency and accuracy of quality control in the production process.
The changes brought by intelligent transformation are obvious to the naked eye: the coating thickness is more uniform, the pass rate is greatly improved, the raw material loss and labor costs are significantly reduced. At the same time, it can stably adapt to the production of large batches of standard workpieces, and also meet the needs of small-batch and multi-category customized orders, perfectly adapting to the current trend of flexible production in the manufacturing industry. Through pulse electric field technology, nano-level film thickness control can be achieved, with an error of ±0.5μm, which is far superior to the ±5μm of traditional spraying, further improving the coating quality.
From the perspective of the downstream application market, the application boundary of electrophoretic technology is constantly expanding. In addition to traditional auto parts, hardware furniture, and door and window profiles, emerging fields such as new energy vehicle structural parts, energy storage equipment casings, photovoltaic accessories, security equipment, and agricultural machinery have higher and higher requirements for corrosion resistance, appearance texture, and service life, leading to a continuous surge in the market demand for high-performance cathodic electrophoretic paint. Globally, cathodic electrophoretic paint accounts for more than 90% of the market, and its high corrosion resistance and excellent throwing power make it widely used in high-end fields such as automobile whole vehicles and high-end parts. Specifically, the demand for electrophoretic paint in the new energy vehicle field is growing at a rate of 26%, far exceeding the 3% of traditional fuel vehicles, becoming a core growth driver.
At the same time, customers no longer only focus on price, but also pay more attention to coating corrosion resistance level, weather resistance, adhesion, environmental qualifications, and delivery stability. This has forced electrophoretic processing plants and coating manufacturers to shift from "competing on low prices" to "competing on technology, quality, and service". This change is particularly obvious in the global market, where high-quality, environmentally friendly, and efficient electrophoretic solutions are more favored by international buyers.
For practitioners in the electrophoresis industry, the current situation is both a challenge and an opportunity. The normalization of environmental compliance forces enterprises to upgrade equipment and optimize formulas; the popularization of intelligence reduces long-term operating costs and improves market competitiveness; the outbreak of downstream emerging tracks opens up new profit space. It is predicted that the global electrophoretic paint market will grow at a rate of 5.0%-5.5% in 2026, and the Chinese market will grow at a rate of 6.5%-7.5%, showing strong growth momentum. In the future, only electrophoretic enterprises with complete environmental qualifications, intelligent production lines, stable quality control, and one-stop supporting services can stand firm in the industry reshuffle and seize more market share.
In the current era of intensified industry involution, only by keeping up with the direction of environmental policies, deploying intelligent production, deeply cultivating the high-end application market, and continuously optimizing processes and services, can enterprises achieve steady growth in the new round of development wave of the electrophoresis industry. For international partners, grasping these trends will help seize market opportunities and achieve win-win cooperation.
