CAS 80-62-6 Methyl methacrylate (MMA), also known as methacrylic acid methyl ester, is an organic compound with the chemical formula C5H8O2. It is a colorless liquid with a pungent, fruity odor. It is used primarily to produce polymethyl methacrylate (PMMA). Additionally, MMA is used in making various coatings, adhesives, paints, and medical devices.
what is methacrylic acid (MAA)?
CAS 79-41-4 Methacrylic acid (MAA) is a polymerizable, unsaturated, monocarboxylic acid functional monomer. In copolymers, low levels (≤5%) of MAA improve latex stability, adhesive properties, wettability and pigment dispersion, as well as allowing for post-crosslinking reactions. MAA is used in copolymers to enhance performance in adhesives, caulks, sealants, paint, coatings, varnishes, printing inks, and textile finishes.
