There are many types of anti-corrosion coatings, and their properties and uses are different. The correct selection is crucial to the anti-corrosion effect and service life of the coating. When choosing:

1. The nature of the surface material of the coated object
For example, iron red and red lead primers can be selected for ferrous metals, and red lead primers not only can not protect aluminum and other non-ferrous metals but will have a destructive effect.

2. The use environment of the coated object
Anti-corrosion coatings are highly specific to the environment, and the most suitable coatings should be selected according to the specific use environment, such as the type of medium, concentration, temperature, and equipment operation conditions.

3. Construction conditions
Appropriate paint varieties should be selected according to the actual conditions of the construction site. For example, in a site with poor ventilation, it is advisable to use solvent-free or high-solid or water-based anti-corrosion paint. Only self-drying paints can be used on sites where baking is not available.

4. Comprehensive effect of technology and economy
It is not only necessary to consider whether the technical performance is excellent, but also economic rationality. When conducting economic calculations, comprehensive consideration should be given to material costs, surface treatment costs, construction costs, coating performance and service life, and maintenance costs.
