Coating for Windscreens

There is no simple answer to the "How long does it last?“ question. On some cars, which are driven infrequently, the coating can last for several years, but if one applies the coating to a taxi which drives 300 miles per day around Long Island, where there is a frequent rain (and sand from local beaches) the coating will last for a shorter period. Formal lab testing informs us that that the coating lasts for the equivalent of 20,000 km but it is proposed that under standard driving conditions one application will last for approximately 6 months (on the taxi windscreen example it may last for only 3 months).

The main impact on the performance of the coating is associated with
A. Quality of application.
B. The amount of abrasion which the screen is subjected to.

Another example:
if a car drives 20,000km around the US during a month-long road trip, in the early summer, it is possible that the windscreen wipers will have been used for only a matter of minutes. After 20,000km the coating will have experienced very little degradation (unless driving closely behind vehicles when transiting a desert) and it will retain strong performance.

If the same road trip is made in the autumn, when there is significantly more light rain, it is possible that the windscreen wipers will have been used on many occasions. This windscreen wiper action will start to abrade the surface. Light, misty rain does not immediately run off the coated windscreen at low speeds and so the windscreen wiper will be used

If the same road trip is made in the winter and let us assume that the rain is torrential, it is highly probable that the windscreen wipers will only need to have been used on rare occasions as heavy / torrential rain runs off the windscreen very rapidly.

Having noted the above one application of the windscreen coating should last for approximately 6 months +/- under normal usage conditions.

The windscreen coating is made from nano scale glass. This new glass layer is very hydrophobic. Water will "bead up" and slide off the slippery glass surface. The coating is only 100nm thick (500 times thinner than a human hair.) It is both super hard, yet flexible at the same time.... this is why it is so durable... the wonders of nano technology!

As noted above, it all depends on weather and environmental conditions but as a general rule application every 6 months is recommended, having noted this, we recommend that after the very first application a second application may be suitable at the 4-month mark. Then every six months afterwards.

Always wash the areas on the windshield that you will apply liquid glass coating to with a suitable cleaning agent. We suggest Biosativa as the best cleaner. Ensure that you thoroughly rinse the screen as washing liquid and similar cleaning agents leave a tenside residue on the surface. This must be rinsed off. It normally takes at least 5 minutes to thoroughly clean a windscreen. After rinsing and drying the screen, deep clean the surface using the cleaning wipe (usually noted as No "1"). Allow the screen to dry for 2 minutes after wiping with the alcohol cleaning cloth then buff the screen and remove the light film which will appear after wiping the area with the alcohol wipe (Use a clean cloth or tissue).

Application of the coating:
Wipe the windscreen with the coating cloth (No "2"). Work quickly and methodically ensuring full coverage of the screen. The cloth will dry within approximately 90 seconds. Vertical and Horizontal wiping actions are recommended.
Use suitable disposable gloves when cleaning and coating. A fingerprint can be 100 times thicker than the coating!

Approximately 5 minutes in warmer weather and 20 minutes in colder weather (see back of wipes).

After Drying: You will see that there is a haze on the surface. This is completely normal. Please use a clean and dry microfibre cloth to buff the surface. The buffing action may take up to 5 minutes.

Yes, you can apply outside. It’s best applied in a shaded area. Do not apply when very humid or when rain is expected within minutes of application. Do not apply in direct "hot" sunlight. If applying in a garage, please remember that the wipes contain alcohol and are combustible. Do not apply on to a hot windscreen. 5-20°C is the suggested surface temperature.

Yes. By using a combination of wire wool (0000) and cerium oxide.

We do not work with discrete nano particles, the SiO² is amorphous molecular scale SiO². Our Liquid Glass coatings are designed as wet-chemical coatings. The dried coatings are approximately 100nm (nanometres) thin and therefore fall under the official definition of “nanotechnology” (“structures” <=100 nm). If the coating does come into contact with the body work, we suggest that area is buffed as soon as possible. The windscreen coating is designed specifically for application to glass.

Maintenance: The coating is very resistant to soiling but micro contamination from vehicle exhausts will sit on the surface. Over time it will be necessary to remove this contamination. Wash the surface with Biosativa or alcohol and the coating will become rejuvenated.

Yes, the coating does withstand freezing. You will also notice improved visibility when driving in snow.
