Abstract
Method and apparatus for agitating an acidic aqueous coating composition containing dispersed particles of an organic coating-forming material are disclosed. Movable vanes are disposed beneath the surface of a bath of the composition. The vanes have a relatively large surface area and are moved through the bath at low speed so that the shear stress imposed on the dispersed particles is minimized. This prolongs the stability of the composition.
