In coating operations, surface defects such as orange peel, brush marks, craters or sagging not only affect appearance, but may also reduce the protective performance of the coating. These common surface defects often result from uneven surface tension of the coating system, improper solvent evaporation rate or poor control of the application environment. How to efficiently obtain a flat, smooth, high-gloss coating surface is a continuous challenge for many coating formulation engineers and applicators.
Targeting this core pain point, Chemi Tech has devoted extensive research to developing a series of high-performance acrylic leveling agents. Through unique molecular structure design, our products can effectively adjust the surface tension distribution during coating curing, promote uniform spreading of the coating on the substrate, and suppress surface disturbance caused by solvent evaporation or uneven reaction. Their function is not simply to dilute the coating, but to precisely intervene at the rheological level to achieve self-leveling of the coating.
Our solution consists of three steps: first, precisely diagnose the root cause of the problem. Our technical team will help analyze the specific type of coating defect and the conditions under which it occurs, whether it is a system compatibility issue or caused by the application environment. Second, targeted product selection. Chemi Tech offers acrylic leveling agents with different functional-group modifications and molecular weights to suit solvent-based, solvent-free and waterborne systems, ensuring perfect compatibility with your formulation. Finally, provide optimized dosage and process guidance. We determine the optimal addition ratio through experiments and recommend suitable stirring and dispersion processes to ensure the additive performs at its best.
For example, we once cooperated with an enterprise specializing in industrial equipment coating. The enterprise was always troubled by slight orange peel in one of its solvent-based topcoats, which was particularly obvious on large flat workpieces. By introducing a specific Chemi Tech acrylic leveling agent at a dosage of only 0.3%, the leveling and spreading properties of the coating were significantly improved. In the end, the surface smoothness of the coating was greatly improved, the gloss increased by more than 10 units, and the customer was very satisfied with the final coating appearance. This improvement was achieved without changing the main resin and main production process, making it both efficient and economical.
