Amino methacrylate copolymer is widely used in the pharmaceutical industry as a coating material for tablets and capsules. It provides a protective layer that controls the release of active ingredients, ensuring sustained or delayed drug delivery due to its pH-dependent solubility. This copolymer is particularly effective in masking unpleasant tastes and odors, improving patient compliance. It is also utilized in oral formulations to protect drugs from stomach acid, allowing them to be released in the intestines for better absorption. Additionally, its film-forming properties make it suitable for creating stable and uniform coatings on various dosage forms.

Beyond pharmaceuticals, it is used in cosmetic products such as creams and lotions to adjust skin condition and enhance moisture retention. It also finds applications in the coatings and paints industry due to its excellent adhesion and durability in various environmental conditions.
