Detailed Explanation of 10 Common Types of Paints and Industrial Coatings Classification
In the fields of industrial manufacturing, construction engineering, automotive refinishing, wood furniture, and equipment anti-corrosion, paint and coating products are highly diverse. The core differences among various coating types mainly stem from the "film-forming substance" or "resin binder."
The film-forming resin determines the hardness, adhesion, weather resistance, corrosion protection, chemical resistance, and service life of the paint film. Therefore, when selecting industrial paints, it is essential to understand the characteristics of different resin systems.
The following will detail the 10 common types of industrial paints currently on the market and their application ranges.
