methacrylic acid uses
99.5% Methacrylic acid (MAA) is a key industrial monomer primarily used to produce a wide range of polymers and copolymers, such as methyl methacrylate (MMA), butyl methacrylate, and ethyl methacrylate, which are building blocks for acrylic plastics, resins, and coatings.
CAS 79-41-4 is also used in producing adhesives and sealants.
MAA methacrylic acid is an additive in detergents (as a dispersant), and in the formulation of ion-exchange resins for water treatment and chemical purification.
