Hydrophobic Coating Ultra-clear Glass Plate

Ultra-clear glass with a hydrophobic coating combines superior optical clarity with advanced water-repellent functionality. The base glass, characterized by its low iron content, offers exceptional light transmittance—often exceeding 91%—providing a crystal-clear, colorless viewing experience. A nano-scale hydrophobic layer, typically composed of modified silica nanoparticles or silicone-based polymers, is applied to the surface.

This specialized coating significantly reduces the glass’s surface energy, causing water to bead up and roll off effortlessly. This “self-cleaning” effect efficiently carries away dust and dirt particles. Crucially, the coating is engineered to maintain the glass’s high transparency, with some advanced formulations achieving a peak transmittance of up to 99.5% while exhibiting a water contact angle exceeding 150° for superior water repellency.

The durable coating also provides resistance against stains, UV radiation, and environmental contaminants. This makes ultra-clear hydrophobic glass ideal for high-end architectural windows, solar panels, automotive displays, and optical instruments where both maximum clarity and minimal maintenance are required.

Water Repellency: The surface causes water to bead up into nearly perfect spheres (with a contact angle often exceeding 110°) rather than spreading out into a thin film.

Self-Cleaning Effect: As water droplets roll off, they effectively pick up and carry away dust, dirt, and debris, keeping the surface cleaner for longer periods.

High Transparency: The ultra-thin nano-coating preserves the glass’s excellent optical clarity and light transmittance (typically over 90%), ensuring no distortion or haziness.

Anti-Fouling: The low surface energy makes it difficult for contaminants like oil, fingerprints, and mineral deposits to adhere to the glass.

Durability: High-quality hydrophobic coatings are engineered to bond strongly with the glass, offering resistance to scratches, UV radiation, and environmental corrosion for long-lasting performance.
