    GMA main uses:

    1. Mainly used in powder coatings, but also used in thermosetting coatings, fiber treatment agents, adhesives, antistatic agents, vinyl chloride stabilizers, rubber and resin modifiers, ion exchange resins and adhesives for printing inks.

    2. Used as a functional monomer for polymerization. Mainly used in the manufacture of acrylic powder coatings. It is used to copolymerize soft monomers with hard monomers such as methyl methacrylate and styrene. It can adjust the glass transition temperature and flexibility, and improve the gloss, adhesion and weather resistance of the coating film. Wait. It is also used in the manufacture of acrylic emulsions and nonwovens. As a functional monomer, it can be used in the manufacture of photosensitive resins, ion exchange resins, chelating resins, medical selective filtration membranes, dental materials, anticoagulants, and non-soluble adsorbents. It is also used to modify polyolefin resins, rubbers and synthetic fibers.

    3. Because it contains both carbon-carbon double bonds and epoxy groups in the molecule, it is widely used in the synthesis and modification of polymer materials. Used as reactive diluent for epoxy resin, stabilizer for vinyl chloride, modifier for rubber and resin, adhesive for ion exchange resin and printing ink. It is also used in powder coatings, thermosetting coatings, fiber treatment agents, adhesives, and antistatic agents. In addition, GMA has also significantly improved the adhesion, water resistance, and solvent resistance of adhesives and non-woven coatings.

    4. In electronics, it is used for photoresist film, electron wire, protective film, and far-infrared phase X-ray protective film. In terms of functional polymers, it is used in ion exchange resins, chelating resins, and the like. For medical materials, it is used for anti-blood coagulation materials and dental materials.
