Description
Glycidyl acrylate (GA) is a monomer that polymerizes in the presence of a free-radical initiator to form polyacrylic acid. This compound is used as a cross-linking agent for coatings, adhesives, and sealing compounds. GA is an excellent starting material for the preparation of cationic polymers with high reactivity and good stability. It has been used as a control agent in the synthesis of polycarboxylic acids and fatty acids. The hydroxyl group on this molecule allows it to be used as a water-repellent coating or sealant.
Chemical Properties
amber liquid
Uses
Glycidyl Acrylate 85% can be used as an adhesive composition.
Application
Glycidyl acrylate is used as monomer (polymers for adhesives and coatings), crosslinking agent (polymers of trialkyltin esters), and epoxy resin diluent.
General Description
Light amber liquid.
Air & Water Reactions
Water soluble.
Reactivity Profile
GLYCIDYL ACRYLATE may be sensitive to polymerizing conditions and/or catalysts. GLYCIDYL ACRYLATE will react with oxidizers.
Hazard
Irritant to skin and eyes
Health Hazard
TOXIC; may be fatal if inhaled, ingested or absorbed through skin. Inhalation or contact with some of these materials will irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Fire Hazard
GLYCIDYL ACRYLATE is combustible.
Safety Profile
A poison by ingestion,
inhalation, and skin contact. Mutation data
reported. A skin and severe eye irritant.
Flammable liquid when exposed to heat or
flame. Can react vigorously with oxidmers.
To fight fire, use foam, dry chemical, CO2.
When heated to decomposition it emits
acrid smoke and fumes. See also ESTERS.
Toxicology
For Glycidyl acrylate (GA), LD50 values of 210 mg/kg bw and 150 mg/kg bw were reported in 2 studies in rats and a LD50 of 89 mg/kg bw was reported in rabbits (NLM). Glycidyl methacrylate (GMA) is classified as hazardous as a Category 1B substance with risk phrase 'May damage fertility' in HCIS (Safe Work Australia). The available data for GMA are consistent with this classification. Given the structural similarity and common metabolite (glycidol), this classification is also warranted for GA.
