Rk. Chang et M. Leonzio, THE EFFECT OF RUN-TIME ON THE INTER-UNIT UNIFORMITY OF AQUEOUS FILM COATING APPLIED TO GLASS-BEADS IN A HI-COATER, Drug development and industrial pharmacy, 21(16), 1995, pp. 1895-1899
Coating experiments were conducted to assess the uniformity using indi
vidual weight gains of glass beads. more aqueous film coating and prol
onging the film-coating diluting the coating suspension did improve th
e coating among glass beads. It appears that run time is an important
underlying factor which affecting the inter-unit coating uniformity.
