In the pursuit of perfect coating performance today, many waterborne coatings formulators and application engineers face a common challenge: surface defects such as cratering, pinholes, orange peel, or poor wetting and spreading during the drying process. These flaws not only severely impact product appearance and feel but can also compromise the protective properties of the coating, leading to customer complaints and cost losses. Traditional additives often address one issue at the expense of another, struggling to find the precise balance between dynamic surface tension reduction, substrate wetting and compatibility, and foam stability.
Chemi Tech deeply understands these pain points. Through in-depth research into interface chemistry, we have developed a new generation of high-efficiency waterborne wetting and leveling agent series. Our solution is not simply an addition but a systematic intervention throughout the entire coating process.
First, accurate diagnosis. We recommend systematically investigating the coating formulation, substrate cleanliness and tension, application environment, and process parameters when encountering surface issues. Common root causes include low substrate surface energy, presence of contaminants, or incompatible trace substances within the system.
Second, targeted additive selection. The core advantage of Chemi Tech's wetting and leveling agents lies in their unique molecular structure design. They quickly migrate to the interfaces between the coating and air, and the coating and substrate, effectively reducing the system's dynamic surface tension and promoting rapid spreading of the coating on low surface energy substrates (such as plastics, old coatings). Simultaneously, the products offer excellent compatibility, preventing new defects caused by their own agglomeration, and possess good foam control capabilities, reducing pinholes caused by bubble rupture.
Finally, scientific addition and validation. We provide professional application technical support to assist customers in determining the optimal addition point and dosage (typically between 0.1%-1.0%), and verify significant improvements in coating surface smoothness, gloss, and appearance through leveling panel tests, contact angle measurement, and real-world condition simulation.
Case Study: A home furnishings manufacturer frequently experienced micro-cratering on metal handle surfaces when using a waterborne topcoat, affecting product grade. Analysis by the Chemi Tech technical team identified the cause as a mismatch between residual mold release agent on the substrate and the coating system. After recommending and incorporating a specific Chemi Tech wetting and leveling agent at 0.3% into the formulation, the cratering was completely eliminated. Additionally, the gloss uniformity and smooth feel of the coating were improved, leading to a substantial increase in the customer's first-pass yield rate.
Choosing Chemi Tech is not just selecting an additive; it is choosing a reliable surface problem solution. We are committed to helping you achieve impeccable coating results and enhance product value through professional chemicals and innovative technology.
