Leveling agents are key additives in the fields of coatings, inks, adhesives, and more, capable of improving the surface fluidity of liquid materials and reducing coating defects such as orange peel, shrinkage cavities, and brush marks. However, with a wide variety of leveling agents available on the market, how should we correctly select the appropriate one?

The core function of a leveling agent is primarily achieved by migrating to the coating surface, reducing the interfacial tension between the liquid and the substrate, and promoting uniform spreading. It optimizes and balances the fluidity of the coating, avoids defects caused by sagging or rapid drying, and inhibits surface tension differences formed by uneven solvent evaporation.

The key factor in selecting the appropriate leveling agent lies in its selection based on the coating system. Different coating systems require different matching leveling agent products. For example, high-temperature curing systems require leveling agents with good thermal stability. Secondly, adjustments need to be made based on the application method. This can be evaluated through small-scale tests, and continuous attention should be paid to its compatibility.

Choosing the right leveling agent requires comprehensive consideration of the coating system, application method, and performance requirements. It is recommended to conduct small-scale tests first, and then gradually optimize the formula to achieve the best leveling effect.
