Surface additives in industrial applications serve various functions to enhance the performance and durability of coatings. Here’s a summary based on the functions you’ve listed:

Leveling and Slip: These additives improve the smoothness of the coating’s application, reducing brush marks and other surface irregularities. They also enhance the slip properties, making the surface less prone to friction and wear.

Leveling and Surface Tension Reduction: By reducing surface tension, these additives help in achieving a more uniform coating thickness across the entire surface, preventing issues like orange peel or craters.

Substrate Wetting: Wetting agents are used to ensure that the coating spreads evenly over the substrate, improving adhesion and minimizing defects like pinholes or fisheyes.

Silicone-free Leveling: These additives provide the leveling benefits without the use of silicones, which can be desirable in applications where silicone contamination is a concern.

Silicone- and Fluorine-free Leveling: Similar to silicone-free additives, these also avoid the use of fluorine compounds, offering an environmentally friendly option that still provides effective leveling properties.

Each type of additive is designed to address specific challenges in the coating process, ensuring a high-quality finish and performance of the industrial product.
