What is Glycidyl Methacrylate GMA CAS 106-91-2?

Glycidyl Methacrylate, commonly abbreviated GMA and also called 2,3-epoxypropyl methacrylate, is a methacrylate ester with molecular formula C7H10O3. It is a reactive monomer used in epoxy-functional acrylic and polymer-modification routes, not a finished resin.

What are the main applications of Glycidyl Methacrylate?

GMA is used to make epoxy-functional acrylic and methacrylic copolymers for coatings, adhesives and powder coatings. It also appears in polymer and elastomer modification, ion-exchange resin synthesis and specialty functional-resin routes.

Why is MEHQ inhibitor added to Glycidyl Methacrylate?

GMA is a reactive methacrylate monomer that can polymerise prematurely, so commercial grades are usually stabilised with MEHQ at about 50-100 ppm. Storage should be cool and protected from light, and the inhibitor level should be considered for the selected polymerisation process.

What typical liquid properties should be expected for GMA?

Glycidyl Methacrylate is normally a clear liquid with density around 1.04 g/cm3 and boiling point around 189 deg C. Its refractive index is about 1.449-1.451, and it has limited water solubility of roughly 0.5-1.0 g per 100 mL at 20 deg C.

Product Description

Glycidyl Methacrylate (GMA) CAS 106-91-2 is 2,3-epoxypropyl methacrylate, with EC 203-441-9 and molecular formula C₇H₁₀O₃.

Synonyms: 2,3-Epoxypropyl Methacrylate; GMA; Methacrylic Acid Glycidyl Ester.

CAS: 106-91-2.

Molecular formula: C₇H₁₀O₃.

It is supplied as a clear liquid.

It is positioned as a dual-functional reactive monomer for epoxy-functional acrylic and polymer-modification routes.

It is a resin-manufacturing input and is not a finished epoxy resin, coating or adhesive.

It is used in epoxy-functional acrylic and methacrylic copolymer manufacture.

It is used in coating and adhesive resin modification.

It is used in powder-coating and specialty polymer-resin production.

It is used in polymer and elastomer modification routes requiring GMA functionality.

It contains both a polymerisable methacrylate double bond and a reactive epoxide group.

It can copolymerise through the double bond while the epoxide remains available for later crosslinking or functional reactions with amines, acids or hydroxyl groups.

Commercial grades are usually stabilised with MEHQ at about 50-100 ppm, with storage cool and protected from light.

Confirm monomer assay, epoxy functionality, inhibitor profile, colour, water and acid-value controls.

It has a density around 1.04 g/cm3, boiling point around 189 C, refractive index about 1.449-1.451 and limited water solubility of roughly 0.5-1.0 g per 100 mL at 20 C.

Store in tightly closed containers in a cool, dry, well-ventilated area, use suitable PPE when handling, and follow the current SDS.
