79-41-4
2-Methyl-propenoic acid
It is produced for use as a building block to make a wide range of polymer-based products
Paint resins
water-soluble polymers
base material for the manufacture of methacrylic esters
Shelf life of the standard stabilized product: 6 months between 20 °C and 25°C from date of delivery.
Maintain the temperature of the methacrylic acid between 18 °C and approx. 35°C. The ideal storage temperature is 20 °C ─ 25°C. Depending on the situation, temperatures up to 40°C may occur during transport.
Below 16 °C the GMAA crystallizes and is depleted of dissolved oxygen and inhibitor. Hence the process of unfreezing has to be done very carefully.
It is registered in REACH.
