About the hardness of coating products:
Recently, it is said on the market that the hardness of the coating is 9H. I have just heard that it is 10H, 11H or even 12H.
Among the Mohs hardness, 10H is the hardest diamond in nature.
Therefore, some brand coating products advertise that their hardness is 9H. In fact, they are not Mohs hardness. Converted to a pencil test method is 4-5H.
In fact, the results of the 9H and 10H products produced by the pencil test method are not good, because we are a factory. We have produced 9H and 10H products, and the durability of the products is very short, only a few days. So at present there is no brand on the market that can reach the hardness of 9H and 10H of the pencil hardness, so everyone should distinguish what unit hardness is used.
At present we KISHO produce the product hardness is 5-7H. Because the hardness is too high product adhesion is poor, so we are pursuing a cost-effective product effects, both hardness and durability. This is also the current international very popular product hardness .
The essence of coating is long-term adhesion and toughness, not just hardness.
