Methacrylate Acid
Undiluted or glacial methacrylic acid [MAA] is produced for use as a building block to make a wide range of polymer-based products that we see and use every day like binders in paints and coatings but also water-soluble polymers, as an interlevant in glass and, as an intermediate for the manufacture of methacrylic acid esters to name but a few.
