Hz info:June 27—Under the witness of Sun Xudong, Member of the Standing Committee of the Hangzhou Municipal Party Committee and Secretary of the Xiaoshan District Committee, along with representatives from government and enterprises, Zhongxi Guoxin New Materials (Zhejiang) Co., Ltd., a core subsidiary of Qingxi Holding Group, signed the Investment Cooperation Agreement for the Industrialization Project of High-Performance Polysilazane and Graphene with the Xiaoshan Economic and Technological Development Zone. This collaboration marks a major technological breakthrough in China’s high-end coating materials sector, successfully breaking the European and American technological blockade and establishing an industrial pilot base for polysilazane and graphene-modified functional coating materials

As the first domestic enterprise to fully realize the localization of polysilazane and graphene-modified functional coating materials, Zhongxi Guoxin has independently mastered the full-process independent intellectual property rights from preparation to application. It has built a complete industrial chain layout spanning raw material mining, extraction, production, application, and sales. The project will be implemented in three phases:

• Phase 1 (Q2 2025): Construct a 5,000 m² R&D center at Building 27, Qianwan Bio-Harbor.

• Phase 2 (Q3 2025): Complete a 5,000 m² pilot and industrial base using existing facilities in the development zone.

• Phase 3 (H1 2027): Invest RMB 1 billion to reserve 100 mu (6.67 hectares) of industrial land and 30 mu (2 hectares) of chemical land, building 150,000 m² of non-standardized factories for mass-producing polysilazane and graphene-modified coatings. Upon full operation, the project is expected to generate an annual output value exceeding RMB 1.5 billion, driving upstream-downstream industrial synergy and injecting new momentum into the regional economy.

Driven by technological breakthroughs and industrial deployment, Zhongxi Guoxin is accelerating the scale-up of graphene applications. On June 25, the company signed a strategic agreement with Transfer Coatings to jointly establish a Graphene and Polysilazane Materials Innovation Center. This partnership aims to advance technological innovation and industrial upgrading in specialty coatings through shared resources and dual-driven institutional-scientific reforms.

Technically, Zhongxi Guoxin’s R&D team has overcome critical challenges in modified synthesis, dispersion, and stabilization of polysilazane and graphene. Its "solvent-free nano-enhanced polysilazane primer-topcoat integrated anti-corrosion coating technology" has been deployed at scale in State Grid Fujian’s power systems, protecting 600,000 transformer facilities with "nano armor." The technology merges the inorganic-organic hybrid properties of polysilazane with the nano-layered structure of graphene, creating a composite coating system that delivers:

High-temperature resistance (-50°C to 400°C)

• Insulation strength >30 kV/mm

• Salt spray resistance >3,000 hours

• Flame retardancy (UL94 V-0)

• Adhesion (cross-cut test) < Grade 11

Compared to traditional three-coat systems, this "primer-topcoat integration" enables construction on live equipment without thorough derusting, cutting per-station construction time by 60%, reducing costs by 30%, and enabling 10-year maintenance-free operation1.

Graphene, as a revolutionary 2D material, shows vast potential in heavy-duty anti-corrosion and new-energy batteries due to its conductivity, thermal stability, and mechanical strength. According to market research, China’s graphene market reached RMB 38.6 billion in 2023 and is projected to hit RMB 46 billion by 2025, dominated by graphene powder (90.7%) versus film (9.3%). Key players like Changzhou Sixth Element ,Ningbo Morsh , and Hangzhou Gaoxi Tech are accelerating application development1.

In graphene anti-corrosion coatings, Sinopec’s Shanghai Petrochemical Research Institute developed five high-performance coatings since 2019, with adhesion >16 MPa and salt spray resistance >2,000 hours. In 2025, these were applied at Chenshan Oil Depot in East China, boosting coverage rate by 64% and extending service life beyond 10 years. SEG Luoyang R&D Center further standardized construction protocols to support industry adoption1.

The Hangzhou project signifies China’s autonomy in high-end coating materials. By integrating full industrial chain deployment , it injects momentum into graphene’s scaled application—from lab breakthroughs to market synergy—reshaping the global specialty coatings landscape through new quality productive forces.
