Some car owners worry about whether the crystal will fall off after the expiry date of the car glass coating, which will affect the appearance. In fact, it is too much to worry about. Glass coating is a transparent protective layer. The crystal composition of Huijiang is silica. When its nano-level composition is used on the paint surface, it is only a very thin layer, which is precisely micron.
Regarding the thickness problem, generally the thicker the better, in fact, it is not the case. In addition, many car owners worry that the temperature of the front car paint will be very high due to the high engine temperature during the driving of the car. Cooling, thermal expansion and contraction lead to gaps between the plating crystal coating and the car paint. The thicker the plating crystal, the easier it is to crack and fall off.
The hardness of our KISHO glass coating products is above 6H, which is the highest value of the Japan Paint Inspection Association (the previous highest value was 9H). Because of the poor adhesion of 9Hglass coating products, after long-term sunlight or hard object impact on the crystalline film, the nano-molecules will split and the film will fall off faster. Now it has been upgraded to a product with a hardness of 6H or higher, which has both hardness and flexibility and super adhesion.
The effect case comes from China
