In industrial coating and material manufacturing, surface defects such as craters, fish eyes, and orange peel often occur due to uneven substrate tension or contamination, leading to non-uniform coating application. Chemi Tech addresses these challenges with high-performance leveling and wetting agents designed to reduce surface tension and enhance flow, enabling rapid spreading and defect remediation.
The solution involves four steps: First, diagnose the defect type and root cause through analysis. Second, select a compatible agent based on substrate characteristics. Third, incorporate the additive at 0.1%-0.5% into the production system. Finally, optimize parameters via leveling tests and validation.
An automotive parts manufacturer faced frequent cratering during primer spraying, resulting in a 15% rework rate. After adopting Chemi Tech's leveling wetting agent, cratering was eliminated, first-pass yield increased to 98%. The product is compatible with water-based and solvent systems and suitable for metals, plastics, and other substrates.
