During coating application and film formation, surface defects such as orange peel, brush marks and cratering are common problems troubling producers and applicators. These problems not only affect the appearance of the coating, but may also reduce its protective performance, leading to customer complaints and directly affecting brand reputation and market competitiveness. The core pain point lies in uneven surface tension and poor flow control during the flow and drying process of the coating system. Faced with these challenges, Chemi Tech provides precise and efficient leveling agent solutions backed by deep technical accumulation. Our approach is not simply adding an additive, but is based on in-depth analysis of your specific coating system, such as solvent-based, water-based or UV systems.
First, our technical team will assist you in problem diagnosis, accurately identifying the root cause of the defects - whether it is the Benard cells caused by surface tension gradients, insufficient substrate wetting, or compatibility conflicts between the defoamer and the system. Next, we will recommend targeted Chemi Tech leveling agent products.
For example, for orange peel caused by residual high-boiling solvents in solvent-based coatings, we provide leveling agents that effectively homogenize surface tension and promote long-lasting flow; for cratering prone to occur in water-based systems, we have products with strong wetting and spreading capabilities.
The solution includes clear steps:
Step One, sample evaluation and problem confirmation;
Step Two, laboratory screening of matching leveling agents and small-scale trials;
Step Three, determine the optimal dosage and process to ensure perfect synergy with your resins, solvents and other additives;
Step Four, provide mass production application guidance and follow-up technical support.
Case evidence: a furniture coating manufacturer, when using a traditional formula, always saw fine brush marks on the film with uneven gloss after drying. By adopting the silicone-modified leveling agent provided by Chemi Tech at a very low dosage of 0.1%-0.3%, the leveling and spreading of the coating were significantly improved. After application, the film was flat and smooth, the brush marks disappeared, and the gloss uniformity was greatly improved. The customer passed acceptance in one go, and production efficiency was also improved. Choosing Chemi Tech means choosing a deep understanding of coating surface science and reliable product performance. We are committed to collaborating with you in innovation, preventing surface defects before they occur, and jointly creating flawless coating results to win market recognition.
