A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Transport classification per the UN Model Regulations / 49 CFR 172.101 Hazardous Materials Table. Confirm against the grade-specific SDS (Section 14) before shipping.
Glycidyl methacrylate (CAS 106-91-2), an epoxy-functional methacrylate monomer. It serves as a crosslinking and adhesion-promoting comonomer in acrylic and vinyl resins, a reactive monomer and diluent in coatings and adhesives, and an impregnant for paper and textiles.
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.
