Hydrophobic Nano Coating for Glass, Facades and Ceramic Surfaces

Ready-to-use silicon dioxide sol-gel coating for glass and ceramic surfaces, also available as a concentrate for volume users. Hydrophobic and oleophobic, food-safe, UV-stable, no change in look or feel, PFOA-free and PFAS-free.

Benefits

Hydrophobic and oleophobic: water beads and runs off, oil and grease sit on the surface and wipe away
Soil-repellent: dust, pollen and traffic film do not bond to the glass, so rain rinses facades and cleaning cycles drop
No change in look and feel: invisible on glass, mirrors, glazed tiles and sanitaryware, no film, no tint
Abrasion resistant: withstands high-pressure and steam cleaners up to 60 bar, depending on the substrate
Food-safe and biocompatible: meets the German food and feed code (LFGB) and EC 1935/2004 for food contact surfaces
Temperature resistant: up to 450 °C peak, suitable for hobs, oven glass and facades in full sun
UV-stable: 3,500 hours of artificial UV weathering with the coating still repelling water
Chemical resistant: stable from pH 2.5 to 12; dried graffiti can be removed repeatedly with Vetro Power Pre Cleaner
PFOA-free and PFAS-free: silicon dioxide sol-gel chemistry, no fluorinated repellents
Coverage: about 800 to 1,000 sq ft per litre of ready-to-use coating (roughly 11 to 14 ml per m²), depending on the surface and method

Performance & Testing

Artificial UV weathering, ISO 11507 method A, 3,500 h (Polymer Service GmbH Merseburg): water contact angle 116.7° on the freshly coated glass and 95.3° after 3,500 hours of UV exposure. Untreated glass measures 10° to 15°. The coating is still strongly water-repellent after the full test.
Flexural strength, DIN 1249-12, DIN 18516-4, DIN EN 12150-1 (Friedmann & Kirchner): coated single-pane safety glass meets the normative flexural strength requirements; the coating does not weaken the glass.
Reflection, FT-IR (IGR, Institut für Glas- und Rohstofftechnologie): no difference between coated and uncoated glass on either the tin side or the air side.
Transmission, UV-Vis spectrometer (IGR): no loss of transmission in the visible range; increased transmission from the mid-visible into the long-wave UV on the coated sample.
Food safety (CBA Chemische Produkte-Beratung und Analyse GmbH): meets sections 30 and 31 of the German food and feed code (LFGB) and the requirements of Regulation (EC) 1935/2004 for consumer goods.
Application: clean with Vetro Power Pre Cleaner so the glass is free of dust, grease and cleaner residue. Apply by HVLP spray or with a soft, lint-free cloth; coverage is about 800 to 1,000 sq ft per litre of ready-to-use coating. Ready-to-use is applied neat. A concentrated version is available for volume users. Surfaces can be handled as soon as the ethanol has flashed off; full hardening in 24 hours at 20 °C, faster with warmth. Test on an inconspicuous area first.

Applying Vetro Power Glass & Ceramic Protect

How Vetro Power Glass & Ceramic Protect is applied: clean with Vetro Power Pre Cleaner, apply by HVLP spray or lint-free cloth, flash-off, then 24 hour hardening at room temperature

Vetro Power Glass & Ceramic Protect water contact angle test results: untreated glass 10 to 15 degrees, coated glass 116.7 degrees, 95.3 degrees after 3,500 hours UV weathering ISO 11507

Where Vetro Power Glass & Ceramic Protect is used

Three of the surfaces the coating is specified for, with the test data that applies to each.

Vetro Power Glass & Ceramic Protect hydrophobic coating on an office building glass facade with rain beading off the glass

Glass facades and windows

Rain beads and runs off instead of spreading, and dirt is released with water. Contact angle on coated glass 116.7°, still 95.3° after 3,500 hours of artificial UV weathering (ISO 11507). Reflection and visible light transmission of the glass are unchanged, and flexural strength to DIN EN 12150-1 is unchanged. Resistant to high-pressure and steam cleaners up to 60 bar.

Vetro Power Glass & Ceramic Protect water repellent coating on a hotel bathroom glass shower screen with water droplets beading

Shower screens, tiles and sanitaryware

Specified for shower screens, glazed tiles, wash basins, toilets and bathroom glass. Water and soil are repelled, so routine cleaning is with water, or water and a mild pH 5 to 7 cleaner for heavier soiling. The coating withstands chemicals from pH 2.5 to 12, and there is no change in the look or feel of the surface.

Vetro Power Glass & Ceramic Protect food-safe coating on a restaurant buffet glass guard and glazed ceramic serving dishes

Food service, kitchens and worktops

Certified food-safe by CBA GmbH to sections 30 and 31 of the German food and feed code (LFGB) and Regulation (EC) 1935/2004, for glass guards, glazed ceramic, worktops and counters. Oil-repellent as well as water-repellent, and heat-resistant to a peak of 450 °C.
