Butyrate dope

An aircraft finishing product having a film base of cellulose fibers dissolved in a mixture of acetic and butric acids. Butyrate dope, also called CAB (cellulose-acetate, butyrate) dope, contains, in addition to the film base, the necessary solvents, thinners, and plasticizers to make it bond to the fabric and shrink it. Butyrate dope has, to a great extent, replaced nitrate dope because it is less flammable than nitrate.
