  • What is Nanotechnology?
    Nanotechnology means, basically, miniaturized technology. Nanotechnology refers to the measurement of mater and the creation particles at the Nano scale. A Nano particle is approximately 10 times 10-9 of a meter. It is hard to imagine just how small nanotechnology is. In simple terms, one nanometre is a billionth of a meter, so; • There are 25,400,000 nanometres in an inch • A sheet of newspaper is about 100,000 nanometres thick • On a comparative scale, if a marble were a nanometre, then one meter would be the size of the Earth.
  • How does nanotechnology apply to Liquid Glass?
    In the last decade, considerable efforts have been made to develop ultra-high-performance Nano coatings. One such Nano coating technology is Liquid Glass. This is where a Nano-scale layer of molecular, particle free glass (500 times thinner than a human hair) is deposited onto the surface of the substrate. The layer is flexible, breathable, highly durable, heat tolerant, anti-microbial and offers non-stick and “easy clean” characteristics. Using a simple wipe on application process the application of Liquid Glass to a substrate is amazingly straightforward.
  • What is Silica Dioxide (Si02)?
    Silica Dioxide or Si02 comes in many forms and one of those forms is something called Liquid Glass. Si02 is essentially microscopic particles of glass and Liquid Glass are those particles suspended in a liquid solution. It turns out that Silica Dioxide is actually very useful stuff. It has been around in various forms for industrial use for over 30 years and is used as a flow agent in lots of everyday products. If you have ever used toothpaste or drank a beer, then the chances are you have consumed Silica Dioxide. The molecules of glass (silicon dioxide/SiO²) come from pure quartz sand, of which there are vast reserves, as silicon dioxide is one of the most abundant compounds on the planet. Just like domestic glass, Liquid Glass coatings are food safe, chemically inert and highly resistant to commonly used cleaning chemicals. The coatings also offer resistance to alkalis, acids and solvents.
  • What is the KEY Liquid Glass Screen Protector?
    There are many types of Liquid Glass, each designed for a specific type of application. For Key to achieve a protective coating suitable for mobile device screens, it had to develop its own, a unique form of Liquid Glass screen protector that works on mobile device screens at the Nano scale. The KEY Liquid Glass Screen Protector is based on Liquid Glass (Si02) nanotechnology. The coating is effectively tiny particles of glass (silica) suspended in a solvent (alcohol). Once applied the coating is only 100nm thick (500 times thinner than a human hair), yet it can dramatically increase the hardness and durability for coated screen. The coating is applied by embedding the glass particles onto the glass substrate by wiping it on. The solvent then evaporates, and the glass particles remain
  • How does the KEY Liquid Glass Screen Protector Work?
    When viewed under a microscope a glass surface is not smooth. It is full of valleys and ridges, which can become points of weakness when exposed to external stress through blunt impact. When the KEY Liquid Glass Screen Protector is applied the glass particles in the coating bond to the glass and in so doing, they fill in these valleys and ridges at the Nano level. This liquid glass layer causes a smoothing out effect on the glass, which significantly reduces the points of weakness. As a result, the hardness of the coated glass increases with a corresponding increase in durability.
  • Is it harmful to my device?
    No not at all, Liquid Glass is a completely inert substance and does not hard your device in any way.
  • Can I take it off?
    No once it has been successfully applied, it bonds with the glass it has been applied to and become part of that glass substrate.
  • Can I use it all over the phone?
    The KEY Liquid Glass Screen Protector is only effective when applied to the glass surfaces on your device. It does not protect any non-glass surface.
  • If my screen is cracked, can I still apply the coating?"
    It is possible to apply the KEY Liquid Glass Screen Protector to a cracked screen, but we would strongly advise against it as you will not be able to register your device for the warranty with a cracked or broken screen and the level of protection offered by the coating will be dramatically reduced. We would always recommend that you replace a cracked or broken screen before applying the Key Liquid Glass Screen Protector.
  • Will the Nano Coating affect the manufacturer's warranty?
    No, the Key Liquid Glass Screen Protector will not affect the manufacturer’s warranty.
  • How do I apply the coating to my device?
    Please follow the in-pack instructions or watch the application video for guidance on product application.
  • How many devices can one pack coat?
    Each Pack is designed to coat one device only – you can only register one device per pack.
  • Do I have to use the App to register my device?
    Yes, you must use the Registration App to test and register your device.
  • Does it make the device shatterproof and scratchproof?
    The KEY Liquid Glass Screen Protector has been designed to increase the level of shatter and scratch resistance of mobile devices under normal use and conditions. It is important to remember that your device screen is still made of glass and if you apply excessive blunt force to any glass surface, it will suffer damage.
  • What is covered by the Warranty?
    If your device screen breaks within 12 months of the date you purchased your KEY Liquid Glass Screen Protector and you have correctly applied the product and registered that device through the Registration App then we will pay a contribution towards your replacement screen up to the value stated on your warranty.
  • What is not covered by the Warranty?
    This limited warranty does not cover screen breakage resulting from catastrophic damage that renders the Device inoperable, including but not limited to liquid damage and destruction of the Device. This limited warranty does not cover screen damage that may have resulted from normal wear and tear or misuse/abuse of the Device. This limited warranty does not cover scratches on your Device screen. This limited warranty does not cover damage to your Device screen if the Product has not been properly installed on your Device. Your Device must have the Product installed and in place at the time the Device screen was damaged and when the Device is sent for inspection or when taken to the repair centre of your choice to be repaired. Company will not be liable for any indirect or incidental damages arising from the use of the Product.
  • When will my coverage begin?
    Your limited warranty must have been registered at protectsyourdevice/key within thirty (30) days of the Product purchase date as set forth on your Product purchase receipt and failure to do so will void the limited warranty. No claim under the limited warranty will be accepted within (30) days of the date of registration. This limited warranty is non-transferable and only applies to the original purchaser and registered Device.
  • How long does the coverage last?
    Your limited warranty coverage starts on the date you purchased the KEY Liquid Glass Screen Protector and is valid for 12 months from that date assuming that has been registered within 30 days of that purchase date.
  • When do I need to register my device?
    You must register your device by downloading and installing the Asfalis Registration App available from either the Apple App Store or the Google Paly Store.
  • What information will I need to register my mobile Device?
    You will need your Warranty Activation PIN included in your product pack and a valid purchase receipt to prove the date of purchase. The registration App will if given the appropriate permissions test your device screen and collect all the relevant device information. You will also need to provide your personal contact details to that we can register the warranty to you.
  • How do I file a claim?
    To submit a claim under this limited warranty, please send an email from your previously registered email address to We will reply by email providing you with a secure link to enable you to quickly and easily submit your claim online. Upon submission of your claim, our customer service team will provide email confirmation and information on your claim status, options, shipment and claim settlement.
