Features & Benefits
Product Highlights
- For use in coatings: semipermeable, excellent film former,strong, flexible
- Characteristics of coating can be modified (permeability, mechanical strength, flexibility) through blending two CAs or CA with CAB.
- For use in tableting directly compressible, matrix for sustained release
- CAB is more hydrophobic than CA.
- Requires a solvent for coatings formulations
- Modify a wide range of film properties through additives
- Adjust sustained release by blending CA with CAB
