Overcoming Polyurethane Coating Surface Challenges: Chemi Tech Leveling Agent Solutions

In the application of polyurethane coatings, adhesives, or sealants, poor surface leveling is a common challenge faced by many engineers. Defects such as orange peel texture, micro craters, brush marks, or uneven wetting and spreading that appear after the coating cures not only severely impact the aesthetic appeal of the product but can also pose potential threats to the protective performance and durability of the coating. These issues often stem from imbalances in system surface tension, poor substrate wetting, or local disturbances generated during the defoaming process.

Addressing these specific market pain points, Chemi Tech has developed a series of high-performance leveling agents specifically for polyurethane systems. Our solution goes beyond simply adding an additive; we provide a systematic application approach designed to optimize the coating surface state at its root.

First, accurate diagnosis is essential. Our technical support team assists customers in analyzing the specific causes of coating defects, whether they originate from the substrate, formulation compatibility, or application environment. Second, scientific selection and evaluation are conducted. Chemi Tech offers various leveling agent models, screening the product with the best compatibility and minimal impact on transparency or other key properties through simulation tests. Finally, the optimal addition process is determined. We guide customers on the best stage for addition, recommended dosage, and suitable mixing methods to ensure uniform dispersion and full effectiveness.

We once assisted a manufacturer of electronic device housing coatings in resolving an issue with dense micro craters on their product surface. Analysis revealed the problem was related to their specific polyurethane topcoat formulation and rapid curing process. We recommended a leveling agent with strong wetting power and dynamic surface tension adjustment capabilities and guided them to adjust the addition sequence and dispersion parameters on the production line. After application, surface craters were completely eliminated, gloss significantly increased and stabilized, strengthening the customer's product appearance satisfaction and market competitiveness.

Choosing Chemi Tech means you not only receive a leveling agent product but also gain professional support for surface optimization of polyurethane systems. We are committed to providing precise technical solutions to help you achieve the ultimate smoothness and perfection of your coating surfaces.
