Frequently Asked Questions
What is another name for glycidyl methacrylate?
Glycidyl methacrylate (CAS 106-91-2, C7H10O3) is also called GMA, 2,3-epoxypropyl methacrylate, and methacrylic acid 2,3-epoxypropyl ester. It is an epoxy-functional methacrylate monomer.
What is glycidyl methacrylate used for?
GMA is used as a crosslinking and adhesion-promoting comonomer that introduces epoxy functionality into acrylic and vinyl resins, as a reactive monomer/diluent in coatings and adhesives, and as an impregnant for paper and textiles.
How does glycidyl methacrylate work as a crosslinker?
The methacrylate group polymerizes into the resin backbone while the pendant epoxide remains available to react with carboxyl, amine, or hydroxyl groups, enabling post-cure crosslinking and adhesion promotion. This dual functionality is why it is used as a comonomer in acrylic/vinyl systems.
Is glycidyl methacrylate an acid or a base?
Neither; GMA is a neutral organic ester (an epoxy-functional methacrylate). Its reactivity comes from the polymerizable methacrylate double bond and the reactive epoxide ring rather than acid/base behavior.
How is glycidyl methacrylate shipped and what is its UN number?
GMA ships under UN 2810 and HS heading 2916.14 (esters of methacrylic acid); confirm current DOT classification and packaging on the SDS before transport. RawSource supplies it in bulk to manufacturers, typically stabilized with inhibitor; request a bulk quote, CoA, and SDS.
What is the REACH and TSCA regulatory status of Glycidyl Methacrylate (GMA)?
Glycidyl Methacrylate (GMA) (CAS 106-91-2) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 203-441-9).
