POWDER MATERIAL FOR ELECTROSTATIC APPLICATION TO A SUBSTRATEAND ELECTROSTATIC APPLICATION OF THE POWDER MATERIAL TO A SUBSTRATE |
摘要 |
This invention concerns a powder material suitable for electrostatic application to a substrate and a method of electrostatically applying said powder material to a substrate. At least some of the particles which constitute the powder material comprise a core and a shell surrounding the core. The shell and core generally have differing compositions and have different chemical and/or physical properties. Components which are likely t o be altered can be placed in the core whilst maintaining the shell compositio n, thus allowing changes in formulation of the powder material without destroyi ng the performance of the material in electrostatic application. The powder material is especially suitable for electrostatic application to pharmaceutical solid dosage forms.
