Product Description

MAHICOAT – L 100   (FOR ENTERIC FILM COATINGS)

“METHACRYLIC ACID COPOLYMER TYPE A”

MAHICOAT - L 100 is an anionic copolymer based on meth acrylic acid and methyl -        meth acrylate. The copolymer corresponds toUSP/ NF "Meth acrylic Acid copolymer. Type A". It is insoluble in acids and pure water. It becomes soluble in a neutral to weakly alkaline milieu by forming salts with alkalis, thus affording enteric film coatings which are soluble in intestinal juice.
