Ashland’s line of fully formulated, easily dispersed and ready-to-use Aquarius™ film-coating systems have a range of functions to suit almost any tablet core. Aquarius film-coating systems present an optimum balance of film strength and adhesion, even on challenging cores. The Aquarius Preferred HSP and HSC coating systems are sprayable at 20% solids, for faster throughput and reduced labor and energy costs compared with conventional, lower-solids coatings.
A smooth, defect-free appearance with crisp logo definition is available with Aquarius film coating systems, whether in clear, white, pearlescent or full-color formulations.
Ashland’s Aquarius film coatings systems can be customized to address a number of special needs:
- Improved adhesion
- Improved flexibility
- Moisture barrier
- Odor and taste masking
- Controlled/delayed release
Ashland Tablet Binding
Binder selection is critical for robust tablet formulation. Recent research by Ashland’s scientists has led to a deeper understanding of the physics of tablet binding and the development of practical tools for binder selection. The exceptional range of binders produced by Ashland ensures you will find the right one for your formulation. Ashland produces binders for wet granulation, dry granulation, direct compression and roller compaction. The tables below contain information to help formulators determine the best binder for each application.
- High tablet hardness
