Frequently Asked Questions - Paint Applications

What is the preferred impeller for mixing and holding paint in my paint kitchen? I work in an automotive factory.

The impeller of choice is a low-shear axial-flow impeller, such as the A510, since it minimally shears the batch. Even at 350 rpm, it won't hurt your product due to the uniform velocities it imparts.

For tint and shade tanks, how do I incorporate dry materials into my batch?

Use an A200 upper impeller for better surface turbulence and locate it approximately 2/3 to 3/4 D below the liquid level.

When can I use a "standard" impeller rather than a high-shear impeller?

Generally, any time pigment extension is not required, but it varies with the type of pigment.
