During coating and ink application, surface defects such as craters, fisheyes, and orange peel are common pain points that directly affect product appearance and performance. These problems are mostly caused by insufficient substrate wetting or poor leveling, especially in water-based systems.
Chemi Tech's water-based wetting and leveling agent reduces system surface tension through a specially designed molecular structure, promotes uniform coating spreading, and eliminates defects caused by substrate contamination or compatibility issues. The solution involves three steps: first, analyze the system polarity and match a suitable additive type; second, optimize through experiments at an addition level of 0.1% to 0.5%; and finally, verify actual performance through flow coating or spray application.
An industrial coatings manufacturer encountered persistent cratering during aluminum profile coating. After adding Chemi Tech's wetting and leveling agent, the coating surface smoothness improved significantly, the defect rate dropped, and interlayer adhesion and water resistance were unaffected. This case confirms the additive's adaptability under complex operating conditions.
Centered on technical service and product innovation, Chemi Tech provides customers with precise and stable application support to help achieve high-performance coating manufacturing.
