The Quartz 7 coating contains ポリシラザン or Polysilazane element that does not require any additional polishing process after application. A crystallised layer will form on the car’s surface after application and a self-reactive chemical reaction. This technology is usually used to produce Semiconductor Insulation Film in high-tech electronics factory. Not only can it be used as a car protective layer, but it is also widely used in aircraft, ships, phone, computer, building materials and a protective layer for other paint or plastic material.
