Cleaning pre film agent is a chemical agent used for surface treatment, mainly used to clean and purify the surface to be coated, providing ideal conditions for subsequent coating processes. Its functions can be summarized as follows:
Removing pollutants: Cleaning the pre film agent can effectively remove grease, dust, dirt, and other impurities from the surface to be coated. These pollutants may have a negative impact on the adhesion and adhesion of the coating, so the use of cleaning pre film agents can ensure good adhesion between the coating and the substrate.
Increase the adhesion of the coating: The cleaning pre film agent improves the adhesion of the coating by cleaning the surface of the substrate, removing the oxide layer and other adverse surface substances. It can provide a clean and uniform substrate surface for the coating, allowing it to better adhere to the substrate, improving the durability and stability of the coating.
Promoting surface activity: Some components in the cleaning pre film agent can change the chemical properties of the substrate surface, improving surface activity and wettability. This helps coatings or other coating materials to disperse evenly and stably on the surface and interact better with the substrate.
Removing oxide layer: For certain metal substrates, cleaning pre film agents can remove the oxide layer on the metal surface, restoring the activity and cleanliness of the metal. This is crucial for the anti-corrosion and coating process of metal substrates, ensuring that subsequent coatings can fully adhere and provide effective protection.
It should be noted that the selection of appropriate cleaning pre film agents should be based on the type of substrate to be treated and the specific application requirements. When using cleaning pre film agents, the instructions and usage methods provided by the manufacturer should be followed to ensure safety and the best cleaning effect.
