Re-yingcai® Hydrophobic Nano Coating for Optoelectronic Glass is an ultra-thin transparent functional coating designed for photovoltaic modules, optoelectronic glass and architectural glazing. A biomimetic superhydrophobic structure combined with photocatalytic performance delivers self-cleaning, enhanced light transmission and durable protection. The coating improves efficiency while lowering maintenance costs and is suitable for photovoltaic power plants, high-rise curtain walls, displays and touch panels operating in arid, dusty, humid and other demanding environments.
Product Features
-
Superhydrophobic Self-CleaningRolling rainwater removes dust with more than 90% self-cleaning efficiency, reduces PV cleaning frequency by 80% and can increase annual power output by approximately 2%.
-
High Transmittance & EfficiencyVisible-light transmittance reaches up to 99%, more than 7% higher than uncoated glass, reducing reflection loss and improving photoelectric conversion efficiency.
-
Durable and StableAfter 8,000 hours of xenon-lamp aging and salt-spray testing, the contact angle remains above 110°. The coating offers 4B abrasion resistance and operates from -40°C to 270°C.
-
Ultra-Thin Nano FilmA film thickness of only 1–1000 nm preserves substrate optics, adheres flexibly without cracking and accommodates curved PV and automotive glass structures.

Superhydrophobic Self-Cleaning with Water Beading
The coating has extremely low surface energy, producing a water contact angle above 110° and nearly spherical droplets. Flowing water rapidly removes dust and stains from the glass through a lotus-leaf self-cleaning effect. This keeps outdoor optoelectronic glass clear for longer, reduces manual cleaning frequency, prevents mineral water marks and supports stable light transmission and photoelectric conversion efficiency.
Strong Anti-Fouling and Easy Cleaning
The nano coating creates a robust barrier against fingerprints, oil and airborne organic contaminants. It blocks direct contact between contamination and the glass substrate, making stubborn stains difficult to attach. Even heavily contaminated surfaces can be restored with a light wipe using a damp cloth, significantly simplifying maintenance for frequently touched interactive glass curtain walls, displays and screens.
High-Hardness, Wear-Resistant Protection
-
Precision nanostructure design provides excellent hardness and abrasion resistance while maintaining hydrophobic performance. The coating resists damage from routine wiping, windblown sand and light scratching, preventing wear-related loss of function. This durable protective layer maintains long-term water and contaminant resistance and extends optoelectronic glass service life in demanding environments.
High Transmittance without Performance Loss
-
Designed specifically for optoelectronic glass, the ultra-thin nanolayer provides strong protection with minimal impact on visible-light transmission. Its material properties may even enhance transmission through reduced reflection. The coating therefore preserves PV power generation, display quality and touch functionality while potentially improving overall optical efficiency.
