The case No. : 106-91-2
The answer : 142.1525
Please : C7H10O3
Glycidyl methacrylate is a colorless, transparent liquid insoluble in water, soluble in almost all organic solvents, and irritating to skin and mucous membranes. Avoid contact with acids, oxides, UV radiation, free radical initiators. Because it contains both carbon-carbon double bonds and epoxy groups in its molecule, it can carry out both radical reaction and ionic reaction. Therefore, it has high reactivity and is an important fine chemical raw material.

Product Application: GMA molecule has two functional groups, active vinyl group and epoxy group with ionic reaction, which can be polymerized by functional group or ionic reaction. Therefore, it can be used for modification of ethylene polymer and polycondensation polymer. GMA can be involved in polymerization in three ways, one is ethylene polymerization, so that the epoxy group is located on the branch, that is,"O" polymer [2]; the other is epoxy ring opening, so that the vinyl group is located on the branch, that is,"V" polymer [3]; the third is a compound with active hydrogen and GMA reaction, ring opening on the epoxy group into a chain. The polymer is modified at the time of polymerization by any one of the above three methods. In coatings, GMA can improve hardness, gloss, adhesion and weather resistance of coatings. It can be used in acrylic coatings, acrylic ester coatings, alkyd resin coatings, vinyl chloride resins and some water-based coatings. Acrylic emulsion, binder and nonwoven fabric can improve the adhesion to metal, glass, cement and polyvinyl fluoride when GMA is used; when used in synthetic latex nonwoven fabric, it can improve its washing resistance without affecting the feel. When used in synthetic resin material processing, it can improve its injection moldability, extrusion moldability, and obviously improve the adhesion with metal. When applied to synthetic fibers, it can improve the coloring power of poorly dyed fibers, improve color fastness, and improve crease resistance and shrinkage resistance. This product can improve the sensitivity, resolution and corrosion resistance of photosensitive resin.
Main Uses:
⑴. Mainly used in powder coatings, but also thermosetting coatings, fiber treatment agents, adhesives, antistatic agents, vinyl chloride stabilizers, rubber and resin modifiers, ion exchange resins and printing ink adhesives.
⑵. Used as a functional monomer in polymerization reactions. Mainly used in the manufacture of acrylic powder coatings, used as soft monomer and methyl methacrylate and styrene hard monomer copolymerization, can adjust the glass transition temperature and flexibility, improve the gloss of the coating, adhesion and weather resistance. It is also used in the manufacture of acrylic emulsions and nonwoven fabrics. As a functional monomer, it can be used to produce photosensitive resin, ion exchange resin, chelating resin, selective filter membrane for medical use, dental material, anticoagulant, insoluble adsorbent, etc. It is also used to modify polyolefin resins, rubber and synthetic fibers.
(3) Because it contains both carbon-carbon double bonds and epoxy groups in its molecule, it is widely used in the synthesis and modification of polymer materials. Used as reactive diluent for epoxy resins, stabilizer for vinyl chloride, modifier for rubber and resins, ion exchange resins and binder for printing inks. Also used in powder coatings, thermosetting coatings, fiber treatment agents, adhesives, antistatic agents and so on. In addition, GMA has also significantly improved the adhesion, water resistance and solvent resistance of adhesives and nonwoven coatings.
⑷. In electronics, it is used for photoresist film, electron ray, protective film, far infrared phase X-ray protective film. In terms of functional polymers, it is used for ion exchange resins, chelating resins, etc. In medical materials, used in anti-blood coagulation materials, dental materials, etc.
