Description of key information
Additional information
Glycidyl methacrylate (GMA) is a clear and colour less organic liquid with a fruity (ester-like) odour.
It's physico-chemical parameters are:
Melting point: -41.5 deg C
Boiling point: 189 deg C (196.8 - 197.9 has also been reported)
Relative density: 1.07 kg/m3 @ 25 deg C
Vapour pressure 4.2 hPa @ 25 deg C
Surface tension: 0.025 N/m @ 20 deg C
Water solubility: ca 50 g/l @ 25 deg C (hydrolysis)
Log P(octanol/water): 0.96 @ 25 deg C
Viscosity: 5.481 cP @ 70 deg F (21 deg C)
Flash point 84 (open cup), resp. 76 (closed cup) deg C
Self ignition temperature: 389 deg C
GMA is unstable in aqeous solution (half life @ 25 deg C at pH=4, 7 and 9, resp. 2.83 days, 3.66 days and 2.22 days).
With a flashpoint of 76 (closed cup) – 84 (open cup) deg C (170 – 185 deg F) and a low volatility (vapour pressure of 4.2 x 100 Pa @ 25 deg C) is glycidyl methacrylate a combustible liquid class IIIA and should be kept away from heat, sparks, flame and any source of ignition.
GMA is stable under recommended storage conditions. Elevated temperatures can cause hazardous polymerisation. Polymerisation can be catalysed by the absence of air, the presence of free radical initiators and peroxides, acids, UV light, bases or high temperature. GMA usually contains an inhibitor (stabiliser) to minimise polymerisation. It contains 45-150 ppm of the monoethyl ether of hydroquinone (MEHQ, CAS#150-76-5).
Avoid unintended contact with activated carbon or silica gel, as this may cause polymerisation. Also avoid contact with cellulose or clay based absorbents, and with incompatible materials such as oxidising or reducing agents, strong acids and bases, metals (cast iron, mild steel, copper, brass) and metal oxides. Use within 12 months and store < 25 deg C.
