A paint wetting agent is an important additive that improves the wetting performance of the paint on the substrate. Wetting agents reduce the interfacial tension between the liquid and solid surface, allowing the paint to spread and adhere better to the substrate, thus improving the uniformity and adhesion of the coating. Wetting agents reduce the interfacial tension between liquid and solid surfaces, thereby promoting uniform spreading of the paint on the substrate.
Their main functions include:
Improve wetting: enhance the ability of the paint to wet the substrate, reducing defects such as shrinkage holes and pinholes.
Improve adhesion: enhance the bonding force between the paint and the substrate, improving the adhesion of the coating.
Prevent floating and mottling: reduce the floating and mottling of pigments and fillers in the paint, improving the appearance quality of the coating.
Promote dispersion: help pigments and fillers disperse better in the paint system, improving the stability of the paint.

Promote dispersion: help pigments and fillers disperse better in the paint system, improving the stability of the paint.
Reduce surface tension: Wetting agent molecules form a thin film on the liquid surface, reducing the liquid's surface tension and making it easier for the liquid to spread over a solid surface.
Penetration effect: Wetting agent molecules can penetrate into the microscopic pores of the substrate surface, further enhancing the wetting effect.
Dispersion effect: Wetting agents can help pigments and fillers disperse better in the paint system, preventing agglomeration.
Building coatings: Improve the quality and appearance of the coating, preventing defects such as shrinkage and pinholes.
Industrial coatings: Improve the uniformity and adhesion of the coating, especially on metal and plastic substrates.
Wood coatings: Improve the smoothness and gloss of the coating, preventing floating color and mottling.
Automotive coatings: Improve the flatness and durability of the coating, especially during spraying.
Printing inks: Improve the spreading and adhesion of the ink on paper and other substrates.
