In today's pursuit of perfect coating performance, many waterborne coating formulators and application engineers face a common challenge: surface defects such as craters, pinholes, orange peel, or poor wetting and spreading during drying. These flaws not only seriously affect product appearance and feel, but may also weaken the protective performance of the coating, leading to customer complaints and cost losses. Traditional additives often address one problem at the expense of another, making it difficult to strike a precise balance among dynamic surface tension reduction, substrate wetting and compatibility, and foam stability.
Chemi Tech understands these pain points well and, through in-depth research into interface chemistry, has developed a new generation of high-efficiency waterborne wetting and leveling agents. Our solution is not a simple addition but works systematically throughout the entire coating process.
First, precise diagnosis. When surface problems occur, we recommend systematically checking the coating formulation, substrate cleanliness and surface tension, application environment, and process parameters. Common root causes include excessively low substrate surface energy, the presence of contaminants, or incompatible trace substances in the system.
Second, targeted selection of additives. The core advantage of Chemi Tech wetting and leveling agents lies in their unique molecular structure design. They migrate rapidly to the coating-air and coating-substrate interfaces, effectively reducing the dynamic surface tension of the system and promoting rapid spreading of the coating on low-surface-energy substrates such as plastics and aged coatings. At the same time, the products offer excellent compatibility to prevent new defects caused by self-agglomeration, and possess good foam-stability control to reduce pinholes caused by foam rupture.
Finally, scientific addition and verification. We provide professional application technical support to help customers determine the optimal addition point and dosage (usually between 0.1% and 1.0%), and verify the significant improvement in coating surface smoothness, gloss, and appearance through drawdown tests, contact angle measurement, and actual working-condition simulation.
Case sharing: a household product manufacturer using a waterborne topcoat frequently saw tiny craters on the surface of metal handles, affecting product grade. After analysis by the Chemi Tech technical team, the cause was identified as residual mold release agent on the substrate combined with poor matching of the coating system. After recommending a specific Chemi Tech wetting and leveling agent added at 0.3% in the formulation, the cratering was completely eliminated, the gloss uniformity and smooth feel of the coating were both improved, and the customer's first-pass yield increased significantly.
Choosing Chemi Tech means not just choosing an additive, but choosing a reliable set of surface problem solutions. We are committed to helping you achieve flawless coating results and enhance product value through professional chemicals and innovative technology.
