Choosing the appropriate leveling agent is crucial for ensuring coating performance, improving production efficiency, and reducing costs. Facing the dazzling array of leveling agent products in the market, how to accurately select them has become a major challenge for coating formulators.

Firstly, it is necessary to clarify the type of coating (oil-based, water-based, UV curing, etc.) and the required properties (such as glossiness, hardness, weather resistance, etc.), and select the matching leveling agent type. The construction environment (temperature, humidity), tools (brushing, spraying, rolling), and substrate properties can also affect the selection of leveling agents. Choose leveling agents that comply with local environmental regulations and have low VOC (volatile organic compound) emissions, while considering the safety and health of operators. Taking into account the impact of price, dosage, and overall formula cost while ensuring performance.

Conduct performance tests such as leveling, drying speed, glossiness, hardness, etc. by simulating actual construction conditions. Select several candidate leveling agents for small-scale experiments, compare their effects, and adjust the formula if necessary. At the same time, for already launched coating products, collect customer feedback on coating appearance and durability as a reference for subsequent leveling agent selection.

With market changes and technological advancements, regularly evaluate existing formulas and adjust the types and amounts of leveling agents in a timely manner. Excessive addition may lead to issues such as coating becoming too soft and reduced scratch resistance, and the recommended amount should be followed. Ensure that the leveling agent is fully dispersed in the coating to avoid local concentrations that are too high or too low. Sometimes a single leveling agent cannot meet all requirements, and the best effect can be achieved by compounding different types of leveling agents.

The correct selection of leveling agents can not only improve the quality of coatings, but also effectively reduce costs and enhance market competitiveness. By following the above principles and methods, combined with practical application experience, coating formulators can select suitable leveling agents more scientifically and efficiently.
