配制方法:
Tablets are finished to a high gloss with a finish-coat of clear "Klucel" solution. Application of this coating is made in the coating pan. The clear overcoat is the "Klucel"-shellac or "Klucel"-ethyl cellulose binder solution (used in the color coating operation) to which is added some "Carbowax" 4000 to improve tablet slip. A typical composition is 4.9 parts "Klucel," 1.3 parts shellac solids, 1.0 parts "Carbowax" 4000, and 93.7 parts by weight of ethanol.
