Flow modifiers dispersed in coating compositions are another potential application where a first molecular weight composition prevents cratering of {HEAD ~ the coating} during deposition on a substrate while another molecular weight composition functions to improve {TAIL ~ flow} and leveling of the coating after deposition as well as, perhaps, promoting release of air trapped in the composition
