How can I overcome the surface defects I’m experiencing in my spray-applied coating?

Charlie Hegedus
Research Associate

In spray-applied, high-speed coatings techniques – and even in traditional applications – the surfactant’s ability to migrate rapidly and effectively to the newly formed surface is critical to achieving defect-free surfaces. The solution is to use a surfactant that can effectively reduce equilibrium surface tension and maintain its performance under dynamic conditions when the rate of surface creation increases. Research and extensive industry testing have shown that low-foam dynamic wetting agents within the Surfynol® and Dynol™ surfactant product lines are ideal solutions to this problem. The optimum surfactant will depend on the specific formulation and substrate; therefore, we recommend selecting the dynamic wetting agents recommended for the particular application in which you will use your formulation. Please refer to the application pages for these product recommendations.
