Pre film agents are mainly chemical substances used to clean and treat surfaces, in order to provide better adhesion, wetting, and durability before coating or painting. Their molecular structural formulas may vary depending on the specific components used, and the following are some common pre film agent components:
Organic solvents: such as alcohols, ketones, or esters, used to dissolve and carry other components.
Surfactants: such as adsorbents, wetting agents, or detergents, used to improve the contact and adhesion performance of coatings to the surface.
Stabilizer: used to prevent chemical reactions, oxidation, or decomposition, in order to maintain the effectiveness and stability of the pre film agent.
Corrosion inhibitor: used to suppress corrosion on metal surfaces and improve the adhesion and durability of coatings.
Deionizing agent: used to remove ions or impurities from water to reduce surface pollution and defects.
It should be noted that the specific formulation and composition of the pre coating agent may vary depending on different applications and manufacturers. If you are interested in the molecular structure of a specific pre coating agent product, it is recommended to refer to the product’s Safety Data Sheet (SDS) or contact the relevant manufacturer for detailed information.
