Functional Coating Technology

Functional Coatings and Ultrasonic Spray Application Technology

Functional coatings are a specialized category of surface coating materials, which are designed to endow substrate surfaces with specific physical and chemical properties beyond the basic anti-rust, wear-resistant and protective effects of ordinary coatings. Unlike conventional decorative coatings that focus on improving surface aesthetics and simple protection, functional coatings take targeted performance optimization as the core. They can effectively modify the surface characteristics of glass, metal, polymer and other substrates, including hydrophobicity, hydrophilicity, anti-reflection, anti-fouling, conductivity and biocompatibility, greatly expanding the service performance and application scope of base materials in various industries.

In the field of glass processing, functional coatings are indispensable core technologies for high-performance glass products. Ordinary glass has single performance and is easily affected by dust, water stains, light reflection and external environmental erosion, which limits its application in high-end scenarios such as optoelectronic devices, architectural optics and precision instruments. After being coated with professional functional coatings, glass can achieve customized functions: anti-reflection coatings improve light transmittance, hydrophobic and anti-fouling coatings keep the glass surface clean for a long time, and special protective coatings enhance the weather resistance and corrosion resistance of glass.

Functional coatings endow base materials with tailored properties including corrosion resistance, biocompatibility, electrical conductivity, hydrophobicity and catalytic performance, which are widely demanded across new energy, medical device, electronic manufacturing and advanced material industries. Traditional coating approaches often suffer from excessive material waste, uneven film formation, over‑spraying and difficulty in controlling thin‑layer deposition. Ultrasonic spray technology generates fine, uniform droplets through high‑frequency ultrasonic vibration, enabling precise, low‑waste deposition of functional coating slurries onto complex‑shaped substrates. It delivers thin, consistent, pinhole‑free coating layers while greatly reducing raw‑material consumption. This combination of functional coatings and ultrasonic spray opens up reliable, scalable manufacturing solutions for fuel cell layers, medical catheter surface coatings, perovskite thin‑films and various functional membrane modification processes, supporting high‑quality mass production of high‑performance components.
