In today's pursuit of the ultimate coating appearance and performance, waterborne coatings often face severe challenges in production and application: poor substrate wetting causing craters and fish eyes; poor system compatibility causing surface defects; and inadequate leveling resulting in orange peel and brush marks. These surface problems not only affect product appearance, but may also reduce the protective performance of the coating, leading to customer complaints and cost waste.
In response to these market pain points, Chemi Tech has intensively developed a series of high-performance waterborne wetting and leveling agents. Our solution is not simply adding an additive, but is based on a deep understanding of coating interface science, providing full-process support from problem diagnosis to precise resolution.
Our specific solution steps are clear. First, our technical team conducts a detailed analysis of your coating system and substrate to precisely identify whether the root cause is insufficient wetting, unbalanced surface tension or poor dynamic leveling. Second, based on the diagnosis, we select the matching wetting and leveling agent from the Chemi Tech product library; these products effectively reduce the dynamic surface tension of the system, promote rapid and uniform spreading of the coating over the substrate and primer, and enhance system compatibility to avoid defects such as Benard cells caused by surface tension gradients. Finally, we provide scientific dosage and process guidance to ensure the additive performs stably in the system without affecting intercoat adhesion or other core properties.
Practice verifies the value of the solution. A furniture coatings manufacturer, when spraying its waterborne clear topcoat, always saw scattered craters in corner areas, and repeated adjustments of resin and defoamer failed to fully resolve the issue. After Chemi Tech technical engineers intervened and conducted systematic tests, it was determined that localized substrate contamination had caused uneven critical surface tension for wetting. We recommended a specific wetting and leveling agent with extremely low dynamic surface tension and excellent substrate penetration. After the customer added it as instructed, the craters were completely eliminated, the uniformity of coating gloss improved significantly, and no side effects were introduced, achieving stable mass production smoothly.
Choosing Chemi Tech means gaining technical empowerment beyond the product itself. We are committed to helping every customer overcome coating surface challenges, making the leap from "usable" to "excellent", and making your waterborne coating products more competitive in the market.
