All-hydrogen polysilazane coating: The core material of the green industrial revolution

1.A revolutionary breakthrough in environmental protection performance
All-hydrogen polysilazane coatings, with their halogen-free and heavy metal-free characteristics, have passed the EU REACH regulation and RoHS 2.0 certification, becoming the preferred solution to replace traditional chromium-containing coatings. It adopts a 100% solid content formula to achieve zero VOC emissions. Moreover, the development of the water-based system has reduced solvent usage by 90%, significantly lowering the environmental load during the coating process. In the protection of refractory materials in incinerators, the SiO₂ ceramic layer formed by this coating can effectively prevent the release of harmful substances at high temperatures, extending the service life of refractory materials by more than five times. The full life cycle carbon footprint of this material is 60% lower than that of traditional coatings and has been included in the key promotion list of the "Guidelines for the Construction of the Green Manufacturing Standard System".

2. Innovative applications in the field of industrial protection
In the petrochemical industry, as a protective coating for the inner walls of boilers, it can resist the corrosion of sulfur-containing flue gas, extending the maintenance cycle from 6 months to 18 months. In the field of architecture, room-temperature curing products form an anti-graffiti coating with a hardness of 5H on the surface of metal curtain walls. Weather resistance tests show that it can still maintain a gloss of over 95% in acid rain environments. In the new energy scenario, this coating is used for the protection of wind turbine blades. It remains crack-free in an alternating environment ranging from -40 ℃ to 120℃, and its performance is 50% better than that of conventional high-strength paints. What is more worthy of attention is that when it is used in combination with epoxy resin, the adhesion grade can reach level 0, meeting the ISO 12944 C5-M anti-corrosion standard.

3. Dual opportunities of market growth and policy dividends
The global market size of all-hydrogen polysilazane is expected to reach 1 billion US dollars by 2025. As the largest consumer market, China has a compound annual growth rate of 15%, among which the demand for electronic packaging materials is growing the fastest. At the policy level, the "Catalogue for the Guidance of Industrial Structure Adjustment (2024 Edition)" has listed it as an encouraged project, and local governments are promoting the industrialization process through tax incentives, research and development subsidies and other means. A certain electronic semiconductor materials project has been approved for construction, with the investment in environmental protection facilities accounting for 15.9%, demonstrating the industry's high regard for green production. The People's Government of Qianjiang City. With the transfer of the semiconductor industry to China, the expansion of 12-inch wafer production capacity will drive the demand for spin-coated glass materials to increase by more than 20% annually.

4. Technological Iteration and Future Development Trends
The newly developed gradient doping technology endows the coating with temperature response characteristics. The surface layer of silicon carbide particles provides high-temperature resistance, and the bottom layer of elastomer network offers anti-vibration toughness. It has been successfully applied to the protection of high-speed rail braking systems. Nano hydrophilic products perform exceptionally well in the field of automotive crystal plating. The super hydrophilic surface with a contact Angle of less than 10 degrees can achieve self-cleaning, and its scratch resistance is three times better than that of traditional crystal plating solutions. More cutting-edge research shows that through vacuum ultraviolet light treatment, this material can be transformed into a high refractive index SiOxNy dielectric layer, which exhibits excellent performance with a light transmittance of over 90% and a water vapor transmission rate of less than 0.001g/(m² · day) in the packaging of flexible electronic devices. With the development of future industries such as 5G communication and quantum technology, this material that integrates high performance, environmental friendliness and intelligent response is becoming the core force driving the green transformation of industry.
