Paint Additives

Leveling Agent

1.Regulates Surface Tension: Quickly reduces the surface tension of coatings or inks and balances the internal and interfacial tension differences within the system, preventing defects such as pinholes, orange peel, or shrinkage caused by uneven tension, allowing the coating to naturally level into a smooth surface.
2.Promotes Interfacial Migration: After application, it rapidly migrates to the coating surface, forming a monomolecular layer at the interface and occupying the “surface advantage,” suppressing surface anomalies caused by impurities in the substrate or system, such as wood splinters or edge shrinkage from metal oil contamination.
3.Improves Flow and Leveling: By reducing system viscosity or imparting thixotropy, it extends the coating’s “open time,” giving the material enough time to fill brush marks or spray spots, minimizing surface defects caused by overly rapid drying.
4.Compatibility and Stability: High-quality leveling agents are well compatible with resins, pigments, and other components, avoiding turbidity, phase separation, or precipitation. They also enhance the coating’s weather resistance and chemical resistance without affecting curing speed or adhesion.

Application
Parameter

Architectural Coatings: Added to latex paints to eliminate brush and roller marks, preventing “blotchy” wall surfaces and improving the uniformity of matte paint gloss. In exterior wall coatings, it also enhances resistance to rain wash-off and reduces sagging.
Industrial Coatings: In automotive coatings, fluorocarbon-based leveling agents can achieve a “mirror-like” smoothness, reducing rework rates. In furniture and wood coatings, they can mask wood grain marks, provide a delicate hand-feel, and improve abrasion resistance.
Printing Inks: In offset inks, they improve ink layer spreading, preventing dot gain or smudging. In gravure and flexographic inks, they eliminate streaks and air bubble marks, ensuring uniform color and smooth surfaces in packaging printing.
Adhesives and Sealants: Reduce bubbles and streaks during application, allowing the adhesive layer to evenly cover the substrate and improving bonding and sealing performance. For example, in window and door sealants, they prevent surface unevenness after curing.
Resins and Composites: In fiberglass and engineered stone production, they improve compatibility between resin and fillers, promote material flow to fill molds, reduce surface defects and internal bubbles, and enhance product appearance and mechanical performance.
