Because it forms strong films with excellent adhesion, ETHOCEL™ Polymers have a long history in film and bead coating for controlled release applications. These polymers can offer a versatile diffusion barrier whose properties can be modified by film thickness (weight gain), level of water soluble pore-forming additives (such as METHOCEL™), plasticizer choice, solvent(s) used, or the viscosity (molecular weight) of ETHOCEL™.

For multiparticulate formulations, Dow Pharma Solutions has developed a new ethylcellulose grade, ETHOCEL™ HP, with a particle size distribution which has been optimized for use with high productivity dry powder coating processes. These processes are capable of offering drug release profiles similar to traditional fluid bed coatings in a fraction of the time and without the use of expensive solvents and solvent handling requirements.
