In the application of polyurethane coatings, adhesives, and sealants, poor surface leveling is a common challenge for many engineers. Defects such as orange peel, tiny craters, brush marks, or uneven wetting and spreading after curing not only seriously affect the appearance of the product, but may also pose a potential threat to the protective performance and durability of the coating. These defects often arise from surface tension imbalance in the system, poor substrate wetting, or local disturbances during defoaming.
In response to these specific market pain points, Chemi Tech has developed a series of high-performance leveling agents specifically for polyurethane. Our solution is not limited to simply adding additives, but provides a systematic application process aimed at optimizing the coating surface from the root.
First, accurate diagnosis is the prerequisite. Our technical support team helps customers analyze the specific causes of coating defects, whether they stem from the substrate, formulation compatibility, or the application environment. Second, we carry out scientific product selection and evaluation. Chemi Tech offers multiple leveling agent models and, through simulation experiments, selects the product with the best compatibility with the customer's polyurethane system that does not affect transparency or other key properties. Finally, we determine the optimal addition process. We guide customers to master the best addition stage, recommended dosage, and appropriate stirring and mixing methods to ensure uniform dispersion and full performance.
We once assisted a manufacturer of electronic device housing coatings to solve the problem of dense tiny craters on its product surfaces. Through analysis, the problem was related to the polyurethane topcoat formulation and the fast-curing process. We recommended a leveling agent with strong wetting and dynamic surface tension adjustment capabilities, and guided them to adjust the addition sequence and dispersion parameters on the production line. After application, the surface craters disappeared completely, and gloss improved significantly and remained stable, strengthening the customer's satisfaction with the product appearance and its market competitiveness.
Choosing Chemi Tech means you gain not only a leveling agent product, but also a set of professional support for surface optimization of polyurethane systems. We are committed to helping you achieve perfectly smooth and flawless coating surfaces with precise technical solutions.
