The Japanese Coatings Association conducted a hardness test on KISHO products. The test result is that the hardness of KISHO Si-701 model is 7H, and the hardness of Si-901 model is 5H. Ceramic coating is used on different paint surfaces, and the hardness displayed is The difference is that the hardness of German cars and Japanese cars is different. The paint of German cars is harder, most of the paint hardness is 4H-5H, while the paint of Japanese cars is softer, the paint hardness is 3H-4H. Therefore, the use of KISHO products will increase the hardness of 1H-2H car paint.
In addition, the hardness of the product is also related to the amount and thickness of the product used.
The hardness of ceramic coating products is different when used on car paint once and twice. The hardness of the two-layer product will be higher than that of the one-layer product. KISHO's ceramic coating products have been tested by the Japan Coatings Association, and the hardness of the paint surface can be increased to 7H when the paint surface is used.
At present, many merchants on the market advertise that the hardness of their ceramic coating products is 9H. Just imagine that the ceramic coating product has only a thin layer applied to the paint surface, which is thinner than the plastic wrap. What about the thin layer? Can reach the hardness of diamonds. As a manufacturer of KISHO, we are responsible for saying that the hardness of the product is as high as 9H or even 10H, and the durability is as long as several years. This is all false propaganda. It is a publicity stunt made by brand owners to sell more products.
In fact, the higher the hardness, the shorter the adhesion of the product. A few years ago, KISHO produced a batch of 9H hardness products, but according to the test of the technical department, the durability of the product was only one week. So we did not let the product go on sale. So facts have proved that the cost-effectiveness of high-hardness products is very low. So KSIHO gave up producing 9H products.
The KISHO product hardness test method is: completely immerse a test board in the product for a period of time, then take the test board out to naturally harden, and draw the test board with pencils with different H hardnesses to get our product hardness results. This is also the most recognized hardness test method in the world.
At present, the hardness of KISHO products is 5-7H. What we are pursuing is a cost-effective product that has both hardness and durability. This is also a very popular product hardness in the world.
