Startup makes 'liquid glass' to protect screens from cracks
A German startup has created a 'liquid glass' formula called ProtectPax to make touchscreens scratch- and crack-resistant. The coating, which claims to last for a full year, also repels water. Using nanotechnology, ProtectPax is said to be as hard as Ruby or Sapphire as it uses titanium dioxide nanoparticles, which close the microscopic wells on the glass.
