How can you produce a thicker Class A foam concentrate?

Thicker Class A foam comes from using more foam concentrate in the mix. When you raise the concentrate percentage, there are more surfactants and thickening agents present in the solution, which builds a denser, more cohesive foam blanket. This thicker film sticks to surfaces better and provides longer-lasting coverage, which helps with cooling and fuel control. Adding more air changes how much the foam expands, not how thick the liquid film is, and mixing with more water dilutes the concentrate, making the foam thinner. Lowering the percentage reduces thickness. So, increasing the concentrate percentage is the direct way to increase foam thickness, within manufacturer guidelines.
