Five Chinese electrophoretic coating makers highlighted for 2026

Five Chinese electrophoretic coating manufacturers are being positioned as key suppliers in a market growing on demand for corrosion resistance, low-VOC finishes, and high-volume surface protection. The group includes Dongguan Yongxin, Guangdong Kodest, Haolisen Chemical Technology, Shanghai Kinlita, and Jiangyin Hengxing Paint.

Why it matters: - Electrophoretic coating is gaining use across automotive, industrial equipment, electrical components, and other manufacturing sectors because it delivers uniform coverage, corrosion resistance, and low VOC emissions. - China is emerging as a major manufacturing hub for E-coat systems as global buyers look for efficient and sustainable surface-treatment suppliers. - The five manufacturers highlighted here represent a cross-section of Chinese capacity for domestic and export markets.

What happened: - A July 9, 2026 industry roundup identified five Chinese electrophoretic coating manufacturers as notable suppliers: Dongguan Yongxin Industrial Co., Ltd., Guangdong Kodest Environmental Protection Technology Co., Ltd., Haolisen Chemical Technology (Jiangsu) Co., Ltd., Shanghai Kinlita Chemical Co., Ltd., and Jiangyin Hengxing Paint Co., Ltd. - The companies were described as serving industries from automotive fasteners and consumer electronics to industrial machinery. - Dongguan Yongxin Industrial Co., Ltd. was profiled as a high-tech enterprise focused on electrophoretic processing for metal surface treatment.

The details: - Electrophoretic deposition is a water-based dip-painting process with high transfer efficiency, often up to 95%. - Cathodic epoxy systems are described as the market leader, with coatings often exceeding 1,000 hours of neutral salt spray resistance under ASTM B117 testing. - Anodic coatings typically maintain around 500 hours of salt spray performance, and film thickness is commonly controlled in the 20–40 micron range. - Yongxin was established in 2018 in Qiaotou Town, Dongguan City. - Yongxin employs 60–80 staff and operates a 4,000 m² production facility that expanded to 10,000 m² total plant area in 2025. - Yongxin’s R&D team includes 5–10 engineers, and annual production capacity reaches 30,000,000 units. - Yongxin runs six electrophoresis production lines, more than 20 general processing units, more than 20 CNC machines, over 10 die-casting machines, and more than 10 metal stamping machines. - Yongxin’s integrated setup combines metal forming, precision machining, and electrophoretic treatment under one roof. - Yongxin holds ISO 9001, ISO 14001, and IATF 16949 certifications and was recognized as a National High-Tech Enterprise in 2023. - Yongxin’s testing lab uses German FISCHER film thickness gauges, Swiss Zehntner gloss meters, Japanese Konica Minolta spectrophotometers, Mitutoyo roughness meters, salt spray testers, constant temperature and humidity chambers, and tape abrasion testers. - Yongxin inspects every production batch for coating uniformity, adhesion, and corrosion resistance. - Yongxin’s anion and cation electrophoretic coatings based on acrylic and epoxy resin can achieve 300 to 1,000 hours of salt spray resistance, depending on resin formulation. - Yongxin coats carbon steel, alloy steel, aluminum alloy, magnesium alloy, zinc alloy, and other metal substrates. - Yongxin processes automotive components, bicycle accessories, CNC-machined parts, and stampings. - Yongxin offers black, white, and custom colors, plus matte or glossy finishes, with typical film thickness of 15–25 μm and ±1 μm tolerance. - Yongxin has supplied parts to Huawei, DJI, OPPO, Panasonic, BYD, VIVO, Apple, and Foxconn. - Yongxin’s product line includes black, white, and color E-coating, UV-resistant formulations, corrosion-resistant formulations, and both anion and cation types. - Yongxin also provides CNC precision machining, die casting, and metal stamping. - Guangdong Kodest Environmental Protection Technology Co., Ltd. focuses on low-VOC electrophoretic paints and waterborne resin systems for automotive aftermarket and general industrial uses. - Haolisen Chemical Technology (Jiangsu) Co., Ltd. develops functional electrophoretic coatings, including UV-resistant and high-hardness variants, for construction machinery and agricultural equipment. - Shanghai Kinlita Chemical Co., Ltd. offers cathodic and anodic E-coat materials with an emphasis on color electrophoretic coatings for home appliance and electronics applications. - Jiangyin Hengxing Paint Co., Ltd. operates a dedicated electrophoretic coating line and supplies metal furniture, radiators, and hardware components with cost-competitive anti-corrosion products.

Between the lines: - The roundup points to a market that is shifting from basic corrosion protection toward tighter performance control, more durable finishes, and stronger environmental compliance. - Companies with in-house R&D, multi-process manufacturing, and testing capabilities appear better positioned to win international buyers seeking single-source suppliers. - The mention of 1,500-hour salt spray resistance as an emerging benchmark suggests competition is moving toward higher-performance coatings.

What's next: - The global E-coat market is projected to grow at a 6.5% CAGR through 2032. - Chinese manufacturers are expected to benefit from supply-chain relocation and rising demand for durable, eco-friendly surface treatments. - Investment in modern equipment and certifications is likely to become a key divider between leaders and smaller competitors. - Buyers seeking more information can visit the company's announcement.

The bottom line: - China’s electrophoretic coating sector is being shaped by scale, certification, and process integration, with Yongxin and four peers positioned to capture more domestic and export demand.
