methylcellulose for film coating
|Microcrystalline Cellulose and Carrageenan
||LustreClear™, All-in-one coating system
||Aquacoat® CPD Cellulose Acetate phthalate
C-A-P NF Eastman is used in solvent based coatings
||Klucel® EF and LF enhance the utility of
HPMC. Eliminates bridging, improve adherence to problem tablet
substrates, reduce the incidence on film cracking on the tablet edge.
|Immediate Release Coatings
||moisture barrier/sealant: use Aquacoat® ECD,
Opadry® AMB, Sepifilm™ LP, Surelease®
taste masking: use Aquacoat® ECD, LustreClear™,
Metolose® SM-4, Surelease®
LustreClear™ is used as an
aqueous clear film coating. It allows for short hydration time prior to
coating and fast drying. Its smooth satin-like finish eliminates edge
wear and logo bridging.
Sepifilm™ LP is a ready to use, gastrosoluble
composition for the film-coating of moisture sensitive solid particles.
Plasticized with stearic acid. Shows significantly lower moisture
permeability compared to PVA and other HPMC based coating formulations.
|Sustained Release Coatings
a complete, optimally plasticized system for modified release.
||Klucel® EF is a highly flexible film
former, and is an excellent subcoat for tablets that are difficult to
||Metolose® SM-4, low viscosity (4mPas),
less tacky, and therefore better than HPMC for fine pellet coating
