Glycidyl Methacrylate (GMA)
Glycidyl Methacrylate (GMA) is an ester of Methacrylic Acid and Glycidol. The characteristic of the property of Glycidyl Methacrylate (GMA) is its dual functionality – due to the methacrylic and epoxy groups. This gives it the possibility to combine the chemical properties of acrylates, reacting with styrene, by acrylates or by ethylene, and epoxies. The epoxy group of Glycidyl Methacrylate (GMA) is capable of different chemical transformations both in the monomer and in the polymers.
Glycidyl Methacrylate (GMA) reacts with different substances (amines, phenols, ketones, carbonaceous acids, which contain halogen and others). It makes it possible to synthesize many new chemical connections. Small additives of Glycidyl Methacrylate (GMA) and its derivatives to different polymeric materials improve their mechanical, optical, adhesive characteristics, chemical, and atmospheric durability.

To prevent polymerization, Glycidyl Methacrylate (GMA) should always be stored in air, and never under inert gases. For the stabilizer to work effectively, oxygen is required. It must contain a stabilizer. Storage temperature should not exceed 35 °C. Under these conditions, the storage stability of one year can be expected. To minimize the likelihood of congestion, the storage procedure should strictly follow the principle of “first come, first come”. For a long shelf life of more than 4 weeks, it is advisable to replenish the oxygen content. Over time, the content of ethylene glycol diacrylate slowly increases. If this component is relevant to your process, Glycidyl Methacrylate (GMA) should be used within 12 months of receipt. The preferred material for tanks and pipes is stainless steel. Carbon steel is also used, although rust formation may occur, which will lead to a problem with product quality (color). Iron (III) -ion has been shown to be a weak initiator of polymerization. If carbon steel is to be used, special treatment should be used to prepare the tank for use. Storage tanks, pumps, and pipes must be earthed. Store containers with Glycidyl Methacrylate (GMA) tightly closed in a cool, dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.
