Cleaning pre film agent is a chemical agent used to clean surfaces and provide pre-treatment, commonly used in the preparation stage of coating processes. Different cleaning pre film agents may have different components and formulas, and the specific content of the main components may also vary. The following are some of the main components that may be included in the cleaning pre film agent:
Surfactants: Cleaning pre film agents typically contain a certain amount of surfactants, such as anionic surfactants, non ionic surfactants, or cationic surfactants. These components can reduce the surface tension of the liquid, help the cleaning agent better moisten and penetrate the treated surface, and effectively remove dirt and grease.
Corrosion inhibitor: Cleaning pre film agents may contain corrosion inhibitors to protect metal surfaces from corrosion. Common corrosion inhibitors include organic amine compounds, phosphates, etc. These components can react with metal ions to form a protective film with corrosion inhibition properties.
PH regulator: In order to adjust the acidity and alkalinity of the cleaning pre film agent, pH regulator may be added. These components can maintain the pH value of the solution within an appropriate range, which contributes to the effectiveness of cleaning and pre-treatment.
Coordination agent (optional): Some cleaning pre film agents may contain coordination agents, such as chelating agents or complexing agents. These components can undergo coordination reactions with metal ions, forming stable complexes and reducing oxidation and corrosion on the metal surface.
It should be noted that the formula of specific products may vary depending on different manufacturers and applications, and the specific ingredient content may vary depending on the design and usage requirements of the product. Therefore, it is recommended to refer to the product manual or consult the manufacturer for specific ingredient content information to ensure the correct and effective use of cleaning pre film agents.
