The contact angle of KISHO nano coating: refers to the angle θ where the tangent of the gas-liquid interface made at the intersection of gas, liquid, and solid passes through the liquid and solid-liquid boundary line. The surface tension can be calculated by measuring the contact angle, but our customers use the contact angle to determine the hydrophobicity and hydrophilicity of the paint surface in order to confirm the surface treatment effect or cleaning effect.
If θ<90°, the smaller the angle, the better the wettability; if θ>90°, the hydrophobicity of the solid surface is better, that is, the liquid is not easy to wet the solid and is easy to move on the surface.
Therefore, nano coating can make the car body easy to clean and maintain. Simply rinse with clean water can be as bright as new, saving a lot of car washing costs.
When it comes to the benefits of nano coating, in addition to being easy to clean, there must be many people who will definitely think: it can increase the brightness of the paint surface. Nano coating can make the car surface brighter, the paint surface is crystal clear and brilliant, and the brightness is more than 95%, while the new car is only about 70%.
The use of nano coating for car paint can make the surface of the car paint very smooth, increase a certain degree of brightness and luster, and even achieve a mirror effect, because in the use of nano coating, the pretreatment of deep clean paint is very important.
For example, through a series of decontamination grinding mud and extreme polishing treatment, the paint surface can be restored to the brilliance of the car paint, making the original small scratches smaller and reaching the point where the naked eye cannot observe. To ensure that the performance of nano coating can be fully utilized.
