Is Glycidyl Methacrylate (GMA) the same substance as 2,3-epoxypropyl methacrylate?

Yes. Glycidyl Methacrylate, GMA and 2,3-epoxypropyl methacrylate are names used for the substance identified by CAS 106-91-2. The offered material should still be matched by the agreed assay, inhibitor level and handling requirements.

Is GMA supplied as a finished coating, adhesive or plastic product?

No. GMA is a reactive industrial monomer used in resin and polymer formulations. The finished coating, adhesive, composite or plastic depends on the selected comonomers, resin, curing chemistry, fillers and processing conditions.

Which GMA details should be confirmed before a reactive resin order?

Confirm identity, assay, colour, moisture, epoxide equivalent, inhibitor content, packaging and storage controls. The batch COA, product TDS and SDS should correspond to the agreed grade and the intended polymerization or curing process.

Glycidyl Methacrylate (GMA) CAS 106-91-2

Glycidyl Methacrylate (GMA), CAS 106-91-2, is a bifunctional liquid monomer used to introduce epoxy and methacrylate reactivity into resins and polymers. Also known as 2,3-epoxypropyl methacrylate, it is used in epoxy-acrylic resin modification, adhesion-promoting copolymers, coatings and composite systems. GMA is a formulation raw material rather than a finished adhesive, coating or plastic. Its suitability depends on monomer composition, inhibitor content, processing temperature and the subsequent curing route. Commercial orders should be matched by assay, colour, epoxide equivalent, moisture, packaging and transport conditions. Batch COA, TDS and SDS can be reviewed against the agreed grade. For a non-epoxy methacrylate monomer, Methyl Methacrylate is a related material to compare separately by polymer design and inhibitor condition.

Product Introduction

Glycidyl Methacrylate (GMA) (CAS 106-91-2), also known as 2,3-epoxypropyl methacrylate, is a dual-functional reactive monomer for epoxy-functional acrylic and polymer-modification routes. The listed material is a resin-manufacturing input for coatings, adhesives and specialty polymers; it is not a finished epoxy resin, coating or adhesive.

Applications

Epoxy-functional acrylic and methacrylic copolymer manufacture
Coating and adhesive resin modification
Powder-coating and specialty polymer-resin production
Polymer and elastomer modification routes requiring GMA functionality

Order Specification and Documentation

The GMA grade is confirmed for the stated resin route, including the agreed monomer assay, epoxy functionality, inhibitor profile, colour, water and acid-value controls. A batch COA, together with the applicable TDS and SDS, is available for the quoted Glycidyl Methacrylate material. Packaging and quantity follow the agreed production requirement.

For related reactive monomer pages used in acrylic, methacrylate or adhesive systems, compare Methyl Methacrylate, Hydroxyethyl Methacrylate, and N-Butyl Cyanoacrylate.
