The Main Uses Of Glycidyl Methacrylate
Because GMA molecules contain two functional groups, active vinyl and ionic reactive epoxy, which can be polymerized through both functional and ionic reactions, they can be used for the modification of ethylene and condensed polymers. GMA can intervene in polymerization in three ways: firstly, during ethylene polymerization, the epoxy group is located on the branched chain, which is an "O" type polymer [2]; The second is epoxy ring opening, which places the vinyl group on the branched chain, i.e. the "V" - shaped polymer [3]; The third is that compounds with active hydrogen react with GMA to open rings and form chains on the epoxy group. Using any of the above three methods, the time for polymer modification in the polymerization reaction. In terms of coatings, the presence of GMA can improve the hardness, glossiness, adhesion, and weather resistance of coatings, and can be used in acrylic coatings, acrylic ester coatings, alkyd resin coatings, vinyl chloride resins, and some water-based coatings.
Acrylic acid emulsions, binders, and non-woven fabrics can improve the adhesion to metals, glass, cement, and polytetrafluoroethylene when using GMA; When using non-woven fabrics for synthesizing latex, improve their washing resistance without affecting the feel. When synthetic resin materials are processed, this can improve injection moldability, extrusion formability, and significantly enhance the adhesion between resin and metal. When used for synthetic fibers, it can improve the coloring power of poorly dyed fibers, enhance color fastness, and enhance wrinkle and shrinkage resistance. This product can improve the sensitivity, resolution, and corrosion resistance of photosensitive resins. This product can be grafted with polyolefin to improve tensile strength and flexural strength. In addition, this product can also be used as a raw material for ion exchange resins, mixed resins, medical selective filtration membranes, anticoagulants, dental materials, non soluble adsorbents, etc. Also used for rubber modification.
