   The 17th China Electronic Copper Foil Technology Symposium will be held in Meizhou, Guangdong Province from November 17 to 19, 2026. The theme of this symposium is Technology-driven, Linking the Future — Building a New Ecosystem for International Cooperation in the Copper Foil Industrial Chain.

As an important domestic copper foil industrial base, Meizhou has established a complete industrial chain of “copper foil — copper clad laminate — printed circuit board”, and nurtured leading enterprises including Yinghua Technology, Jiayuan Technology, Longyu Electronics and Bomin Electronics. Hosted in Meizhou, the symposium aims to leverage its industrial cluster advantages and build an in-depth docking platform for the global copper foil industrial chain.

As a technology-based enterprise integrating R&D, manufacturing and trade, our company has long been engaged in electronic chemicals and copper foil additives and will participate in this symposium.  Copper foil electrodeposition and anti-oxidation treatment are critical to copper foil quality. Traditional protein peptides used in electrodeposition additives suffer from poor stability and susceptibility to oxidative deterioration, which restrict coating quality and production efficiency. The post-treatment of copper foil also requires integrated solutions that balance corrosion inhibition and interfacial adhesion. To address these industry pain points and customer demands, our company will showcase four innovative products covering both the electrodeposition and post-treatment processes of copper foil during the conference, as detailed below:

To tackle the drawbacks of poor stability and easy oxidation of protein peptide additives, we has developed synthetic alternatives: Aliphatic Polyoxyethylene Ether Sulfonate (NEOS) and Branched Aliphatic Polyoxyethylene Ether Sulfide (NEOS‑3). Both are chemically synthesized innovative electroplating additives mimicking the molecular structure of protein peptides, serving as direct substitutes for conventional protein peptides with equivalent or superior electrochemical performance.

NEOS: Features strong cathode adsorption capacity, improves coating brightness and bright working range, and markedly boosts the tensile strength of lithium-ion battery copper foil. It delivers flatter deposits with lower Rz values, suitable for low-profile lithium copper foil processes. It resists oxidation during solution preparation and storage with excellent chemical stability, specially designed for lithium copper foil electrodeposition.

NEOS‑3: Retains the electrochemical characteristics of protein peptides, improves coating wettability and broadens the bright operating window. It boasts stable chemical properties and good storage resistance, and is compatible with both lithium-ion battery copper foil and PCB copper foil electrodeposition for wider applicability.
For copper foil post-treatment, we offer Benzotriazole Silane (PCU‑1214) and Benzotriazole Silane Oligomer (PCU‑B). Both are bifunctional organosilicon products containing benzotriazole and silane groups, providing dual functions of copper corrosion inhibition and interfacial adhesion enhancement.

PCU‑1214: High-purity benzotriazole silane monomer with a well-defined molecular structure. It combines copper anti-corrosion performance and silane coupling effect, allowing customers to conduct on-demand hydrolysis and formulate customized film-forming systems on-site.

PCU‑B: Pre-hydrolyzed oligomer derived from PCU‑1214, ready for use directly out of the drum without on-site hydrolysis required. Its oligomer structure forms a more uniform and dense film with good storage stability and easy operation.

Committed to technological innovation, we strive to improve product quality and customer experience. Our goal is to continuously develop new products to meet the growing demands of the electronic copper foil industry and deliver high-quality services and support to customers.
We look forward to meeting you in Meizhou to discuss the future development of the electronic copper foil sector!  Please follow our official website for further updates on new product details and market trends.
