应用
Kollicoat Protect is a ready-to-use moisture barrier system for use in combination with pigments. Kollicoat polymers can be employed as film coatings (intelligent surfaces) with controlled-release agents, for instant-release or sustained-release applications. Kollicoat polymers can be used with all standard coating equipment and are cost-effective, delivering maximum quality in terms of function, stability, and appearance. This research grade product is intended for use in R&D and development only.

The objective of this study was to receive detailed information on the mechanism of drug release from polyvinyl acetate (PVAc)/polyvinyl alcohol-polyethylene glycol graft copolymer (PVA-PEG) coated Propranolol HCl and Theophylline tablets. For this purpose the coating composition (PVAc/PVA-PEG: 90/10 and
