Title: Coating of articles with organic cellulose esters
IPC: B05D3/02
Filed: 1961-03-06
Abstract: An article is coated with a cellulose ester by preheating it to above the normal maximum preheating temperature (i.e. that temperature above which the article cannot be preheated without obtaining coatings susceptible to hairline or other cracking), bringing it into contact with the powdered cellulose ester long enough only to form a film-like coating, removing it from the powder, adjusting the article to a normal pre-heating temperature and thereafter bringing it into contact with the powder at a normal preheating temperature long enough to form a relatively thick layer.  The article may be allowed to cool from the first temperature to the second, or may be allowed to cool to room temperature and subsequently be reheated.  The surface to be coated may first be sand-blasted.  In an example an iron plate is coated with cellulose aceto-butyrate; cellulose aceto-propionate may also be used.  The powder may be applied by spraying or by dipping in a quiescent or fluidized bed of particles.
