Nano-Scale Liquid Glass Coatings

Mobile Phone Coatings

Mobile Phone Protection

CCM GmbH is the world's leading manufacturer of "Liquid Glass" coatings for mobile phones. CCM supplies wipes and kits for private label customers in more than 60 countries.


The application of a protective layer of liquid glass to a phone is very simple and the advantages are:

  • Mobile phone becomes easy-to-clean
  • Fingerprints can be removed with a dry wipe
  • Water-repellent
  • Screen gains significant protection against micro scratches
  • Screen becomes approximately 30% harder
  • Phone becomes „biostatic“, meaning the coating significantly inhibits the development of bacteria
  • Gamma wave emissions are reduced significantly (Gamma waves are highly penetrative and damage human cells)
  • No need for an unattractive protective film (significantly reduces plastic waste) and no bubbles
  • Super easy and fast to apply
  • Invisible / undetectable protection
  • Usable for all mobile phones, including „Edge“ models
  • Can also be used for the rear "glass" of some mobile phone
  • Protects the all-important lenses of mobile phones
  • No impairment of the touch & button functions, scrolling becomes more pleasant ("better haptic experience")
  • Sharper playback of videos
  • Durable for approximately one year
  • Award-winning technology
  • TÜV tested (all claims are based on independent testing)
  • Heat tolerant to approximately 250°C

The main component of the coating is "SiO2" (silicon dioxide = glass), these glass molecules are created from pure quartz sand, one of the most abundant raw materials in nature. SiO2 is used in toothpaste and it is also naturally present within the human body.


Our Mobile Devices Coating has passed these TÜV tests:

  • MSZ ISO 18593:2008: Microbiological Test
  • MSZ 9640/41:1983 Scratch hardness test with spring ball rod
  • MSZ EN ISO 15184:2013Pencil Hardness Test
  • Sessile drop method Water-Repellent, surface tension, contact angles
  • DIN 51 155 Impact Test
  • ICP-MS MSZ EN ISO 17294-2:2005 Metal content of the wipes
  • ICP-MS + XRF RoHs screening test

The History of Liquid Glass Mobile Phone Coating

CCM GmbH from Overath near Cologne is proud to be the world's first company to bring Liquid Glass coatings to the market. Since our founding in 2006 by Bernd Zimmermann, we have been committed to developing, producing, and selling innovative protection solutions for mobile phones in over 80 countries worldwide.

In 2011, we revolutionized the industry with the first Liquid Glass coating specifically designed for mobile phones. At that time, when the concept of the "smartphone" was still in its infancy, most mobile phone displays were made of plastic. Our first coating introduced unprecedented scratch resistance and water repellency, which immediately garnered significant media attention. Soon, we were selling the product in over 60 countries, both under our own brand and as an OEM product for our customers.

In 2017, we launched the second generation of our coating, optimized for the now widespread glass displays. With the innovative component to reduce Y-wave radiation by up to 80%, we made smartphones healthier. Despite the challenge of low-quality Asian copies flooding the market temporarily, we remained undeterred.

2023 marked the introduction of the third generation of our smartphone coatings, adapted to a rapidly changing market with a multitude of new smartphone providers. Our Liquid Glass coating is the ideal solution for all smartphones, both for the front and the increasingly glass-backed devices. Especially since the Corona pandemic, health protection has become more important than ever. Our biostatic coating ensures that bacteria and viruses cannot survive on the surface.

Our Liquid Glass coating, developed in Germany, effectively blocks 80% of Y-wave radiation, as confirmed by independent tests. It significantly increases scratch resistance and provides long-lasting water repellency, as evidenced by numerous applications and customer feedback.

The history of smartphone coating will continue to be written. CCM will always be at the forefront of innovation, responding to new market demands.
