Product Description

Methacrylic Acid is a carboxylic acid monomer used as the core building block for methacrylate esters, acrylic resins and a broad range of polymeric materials. It serves as a reactive intermediate in coatings, adhesives, sealants, elastomers and specialty chemical synthesis where methacrylate functionality imparts hardness, weatherability and optical clarity.

Application

  • Polymer & resin monomer
    Methacrylic acid is a primary monomer or co-monomer for acrylic and methacrylic resins used in coatings, adhesives and sealants.

  • Acrylate ester production
    Used to manufacture methyl, butyl and other methacrylate esters that serve as solvents, plasticizers and specialty monomers.

  • Adhesives & sealants
    Functionality-providing raw material for pressure-sensitive adhesives, structural adhesives and high-performance sealants.

  • Protective coatings
    Feedstock for weather-resistant, UV-stable coatings and lacquers where hardness and clarity are required.

  • Ion-exchange & specialty polymers
    Monomer for ion-exchange resins, hydrogels and specialty functional polymers after appropriate modification.

  • Chemical intermediate
    Intermediate in syntheses of pharmaceuticals, agrochemical intermediates and specialty additives where methacrylic functionality is required.
