Hydrophobic Nano Coating for Glass, Facades and Ceramic Surfaces

Vetro Power Glass & Ceramic Protect makes glass and glazed ceramic hydrophobic and oleophobic, so water, oil and dirt stay on the surface and wipe or rinse off. It is soil-repellent, abrasion resistant, food-safe, UV-stable and temperature resistant to 450 °C, and it does not change the look of the glass. It is PFOA-free and PFAS-free and covers about 800 to 1,000 sq ft per litre of ready-to-use coating.

In artificial UV weathering to ISO 11507 for 3,500 hours the water contact angle fell only from 116.7° to 95.3°, against 10° to 15° on untreated glass, so the coating was still strongly water-repellent at the end of the test. Service life on a building depends on exposure and on how the glass is cleaned. Reapply when water stops beading.

Yes. It was developed for industry and trade: glass facades, curtain walls, shopfronts, hotel bathrooms, sanitaryware, glazed tiles and processing equipment. Because dirt does not bond to the coated surface and rain rinses it away, facade cleaning intervals and the scaffolding, manpower and disruption that go with them come down.

By independent institutes: artificial UV weathering (ISO 11507, 3,500 h), flexural strength of coated safety glass (DIN 1249-12, DIN 18516-4, DIN EN 12150-1), reflection by FT-IR and transmission by UV-Vis spectrometry, and food-contact safety to LFGB and EC 1935/2004. The results are listed under Performance and Testing on this page.

Clean the glass first with Vetro Power Pre Cleaner so it is free of dust, grease and cleaner residue. Apply by HVLP spray, or wipe on with a soft, lint-free cloth, working square metre by square metre and avoiding ponding. Test on an inconspicuous area first. The surface can be handled as soon as the ethanol has flashed off and is fully hardened after 24 hours at 20 °C.

Both. The ready-to-use grade is applied neat. A concentrated version is available for volume users; it keeps for 2 years unopened.

At least 2 years in the unopened original container, and 6 months once opened. Store between minus 5 °C and plus 30 °C, tightly closed, away from heat and open flames; the product is flammable.

Water is usually enough. For heavier soiling use water with a mild, neutral cleaner of pH 5 to 7. Dried graffiti is removed by spraying Vetro Power Pre Cleaner on the area, leaving it a few minutes and wiping; this can be repeated. Avoid abrasive pads, hydrofluoric acid and strongly alkaline chemicals such as bleach and caustic soda, which shorten the life of any coating.

The liquid itself can vary slightly in colour from batch to batch because of the raw materials used; this has no effect on the coated surface. On the surface, apparent colour differences come from the glass structure, gloss level, application and light, not from the coating, which is invisible once cured.

All non-absorbent glass and glazed ceramic: windows, glass facades, porches and canopies, mirrors, lenses, shower screens, glazed wall and floor tiles, wash basins, toilets, winter gardens and worktops. It is not for absorbent unglazed ceramic or stone; for those see Vetro Power Porous Stone Protector.

Yes. The coating is temperature resistant up to 450 °C peak, so it can be used on ceramic hobs, oven and fireplace glass, and on facades and canopies exposed to full sun.

Yes. The coating meets sections 30 and 31 of the German food and feed code (LFGB) and Regulation (EC) 1935/2004 for consumer goods, tested by CBA GmbH. It is used on glass worktops, splashbacks, glazed tiles and glass in food processing areas.

No. Measured by UV-Vis spectrometer at IGR, coated glass showed no loss of transmission in the visible range, and slightly higher transmission from the mid-visible into the UV. Reflection measured by FT-IR was unchanged. This is why the same coating is used on solar glass.

Water beads and runs off the coated screen instead of drying in place, so far less of the mineral residue that forms limescale is left behind, and what does form is on the coating rather than etched into the glass and wipes off with a neutral cleaner. Squeegeeing after use extends the effect.

The coating does not change the look and feel of the surface, so a tile keeps the slip resistance it had before. It is not an anti-slip treatment; for wet floors that need added grip see Vetro Power Anti-Slip Protect.
