METHYL ACRYLIC ACID Chemical compatibility with O-rings, rubbers, & plastics

Methyl acrylic acid, more commonly called methacrylic acid or MAA with the formula C4H6O2, is a colorless liquid used as a monomer in the production of methacrylate resins and polymers. These materials are widely used in coatings, adhesives, plastics, and ion exchange resins. In industrial equipment, methacrylic acid may contact O-rings, rubber seals, gaskets, and plastic components, so compatibility should be evaluated to prevent swelling or material degradation. Exposure can cause skin, eye, and respiratory irritation, making proper storage, safe handling procedures, ventilation, and appropriate PPE essential.
