Abstract: Certain glycerides are effective flow-promoting agents in powdered acrylic coating formulations. As a powdered acrylic resin coating material is applied by electrostatic sprayer means to a substrate, a rough layer of discrete particles is formed. To produce a commercially acceptable coating, this layer must be fused into a continuous film and induced to flow into a smooth, glossy finish. The subject glycerides, which may be acetylated, promote such flow and produce a surface finish equivalent to that of the conventional acrylic paints which employ an organic solvent vehicle.
