In January 2026, Wuxi Juhe Hi-Tech, incubated by Shanghai Hanfu, made a major breakthrough in the field of polysilazane high hydrophobic coatings. Its developed product raised the hydrophobic angle of polysilazane to 120° without fillers, with hardness ≥8H, and also has excellent properties such as high temperature resistance and strong adhesion, breaking the traditional cognition of superhydrophobic coating construction. The hydrophobic property of polysilazane coating is jointly determined by chemical composition and micro-rough structure, and can be upgraded from hydrophobic to superhydrophobic after chemical modification.
    With advantages like thermal stability, UV aging resistance and corrosion resistance, the coating has significant application value in anti-freezing, ice-phobic, metal anti-corrosion and other fields. Its F02W02 product can withstand 5% hydrochloric acid corrosion for 30 days. Polysilazane integrates organic hydrophobicity and inorganic ceramic properties, and can in-situ construct stable rough structures, solving the industry pain point of insufficient durability of traditional protective coatings and opening up a disruptive technical route. It is regarded as the core material of the next-generation high-performance protective coatings, and Wuxi Juhe Hi-Tech deeply cultivates the petrochemical anti-corrosion field to provide professional solutions.
