What is the difference between coating and coating?

1, the coating

Coating is a solid continuous film obtained by the application of coating at one time. It is a thin plastic layer coated on metal, fabric, plastic and other substrates for protection, insulation, decoration and other purposes.Coatings can be gaseous, liquid, or solid, and the type and state of coatings are usually determined by the substrate to be sprayed.

Commonly referred to as coating, generally speaking the thickness should be a little bit thicker, micron level, for example, the TiN coating on the tool plating system, the thickness should be more than 1 micron, we can also call it film layer.There are also decorative coatings, such as black, gold, white, rose gold, and so on, these can be called as coatings.

2, optical coating

Coatings, which we call thin films, are usually nanoscale and are used mainly in optical films.

The advantages of thin film optical coating are as follows:

1. Anti-oxidation, anti-fouling, anti-scratch, long-lasting luster.

2. Maintain the surface coating for a long time.

3, different luster.No matter how much dust and dirt is attached to the surface, the flash can be seen.

4. All cars can be used externally.

5, not affected by the external harsh weather, use as usual.

6. It can be reused.The car which has been plated with film can continue to be coated on the surface to further develop the protective effect.Make his long house shine.

7. Prevent feces and insects.

8. Hydrophobic.
