Purpose of Use and Primary Targets for Coatings
| Purpose | Primary Target | Deterioration Factor |
|---|---|---|
| Corrosion Resistance | Mainly metals | Oxygen, Water |
| Weather Resistance | Mainly plastics | Ultraviolet (UV) rays |
| Decorative Properties | All materials | - |
To add strength, it is crucial to clarify the purpose of the coating for the specific target object.
Roles of Coatings
| Characteristic | Content |
|---|---|
| Mechanical Properties | Provides durability, lubrication/anti-slip properties. |
| Separation Properties | Provides waterproof, gas barrier properties. |
| Coating Properties | Provides adhesive, water-repellent, antibacterial properties. |
| Heat Resistance Properties | Provides heat resistance. |
To add functionality, it is essential to select a coating with the necessary characteristics.
Coating Methods
| Coating Methods | Precision | Skill Dependency |
|---|---|---|
| Brush/Roller Coating | Low | High |
| Dip Coating | Low | High |
| Electrodeposition Coating | High | Low |
| Atomization (Spray) Coating | High | High |
Select the optimal coating method based on the target object and the type of coating.
