Thermo Scientific™ Methacrylic Acid 99% Stabilised is a high-quality monomeric organic acid used extensively in polymer chemistry, coatings technology, adhesive formulation, textile auxiliaries, and materials research. Stabilised with hydroquinone (HQ) or hydroquinone monomethyl ether (MEHQ) to prevent premature polymerisation, this reagent offers exceptional stability and purity for both laboratory and industrial processes.
Methacrylic acid is a key precursor for the synthesis of methyl methacrylate (MMA), methacrylamide, N-substituted methacrylamides, acryloyl chloride, and various specialty methacrylate derivatives. It is also widely used to enhance adhesion in coatings and adhesives and plays an essential role in the formation of poly(methacrylic acid)/montmorillonite nanocomposites, which are utilised in leather tanning and surface modification applications.
