»UNICOAT AQ II IS HPMC BASED AQUEOUS (Water) FILM COATING POLYMER WITH
11% SOLID CONTENT.» This technique has been replaced by film coating technology. This technique was started
with the use of organic solvents but now has been replaced with aqueous film coating
due to environmental and regulatory considerations. Moreover, the cost of any organic
solvent is more than the cost of purified water. Therefore, the conversion from organic
solvent-based coating to aqueous-based coating makes the coating process more
economical, though initially, it may need a little investment to upgrade the coating facility.
