This product pioneered a castor oil-modified blocked polyurethane prepolymer structure, which was developed by integrating the following technologies: low free cyanate control, reduced screen printing pore size, low-temperature baking, and the use of a blocking agent. It has achieved four major improvements: 1. Significantly enhanced print stability, with a print duration of over 20 hours (industry best: 16 hours); 2. Welding tensile force > 1.37 Newtons (industry best: 1 Newton), ensuring product reliability; 3. Screen printing pore size is less than 10 microns (industry best: 14 microns), promoting fine manufacturing; 4. The delamination temperature is 90 (the lowest in the industry: 120), significantly reducing the unit consumption of silver paste and production costs. This technology has been evaluated as a scientific and technological achievement and has reached the international advanced level.
In addition, the heterojunction technology route is currently the only one suitable for the concentrated stacking of perovskites. The technology of this product adds value to the sustainable development of the industry. By promoting this green production technology and practice, the industry has been guided to develop in a greener and more sustainable direction, playing a positive exemplary role in environmental protection and sustainability. This product has also been included in the 2025 Green Technology Promotion Catalogue of Guangzhou City.
With innovative technology, this product has broken through the traditional manufacturing bottleneck. As a key basic material for manufacturing, it is widely used in core fields such as energy, electronics, and semiconductors, effectively promoting the innovation of industrial technology and domestic substitution. With its outstanding performance, it has won high recognition from users and injected strong impetus into the independent and controllable industrial chain and high-quality social and economic development.
