The main components of the pre film agent

Pre coating agent is a chaical substance used to enhance adhesion and surface treatment before surface coating. Its main components may vary depending on the application, but typically include the following:

• Surfactants: These compounds help reduce surface tension, allowing the pre coating agent to better wet the target surface and improve the adhesion of the coating.

• Solvents: Solvents can help other components in the pre coating agent to be evenly dispersed and quickly evaporate after coating, promoting rapid drying of the coating.

• Chelating agents: These compounds can form complexes with metal ions, thereby improving the adhesion between the pre film agent and the metal surface.

• ​Additives: Pre film agents may also contain some other additives, such as antioxidants, stabilizers, or dosages to improve rheological properties, in order to enhance the performance and stability of the coating.

The proportion and specific formula of these ingredients may vary depending on the application and required performance.
