MAA is formed via the acetone cyanohydrin (ACH) route to manufacture MMA and is used in many applications, which include the production of speciality methacrylates for automotive coatings, in cement modifiers, NBR latex for disposable synthetic rubber gloves and in vinyl ester resins. MAA contributes a number of additional beneficial properties including surface adhesion, toughness and chemical resistance.
Mainly used in paints area, insulated material, adhesive ion-exchange resins and others.

Transportation in cold weather, MAA condensation risk increasing. Condensation is caused by the initial temperature, transport time, external temperature, the capacity of tank insulation and heat loss prevention. In order to reduce these factors’ impacting, recommend to using special temperature control system in transportation, then steam can reduce the risk of products condensation.
Hazard Class: 8
UN/NA: UN2531
Packing Group: III
To avoid the sunlight in the storehouse; to control the temperature at 18℃to 40℃ (64-104 Fahrenheit degrees); to leave 4 inches wide channel around the venue; to supply enough oxygen among monomer (recommend to using greenhouse with water transfer system); to require to ventilate and oxygenate before out of the works and this measure is necessary during the transport; need to open the cap and ventilate before storing in the warehouse so as to have enough oxygen to make inhibitor working, avoiding the polymerization of MAA.
If freezing or melting occurring in transportation, please note:
No use strong steam or electric heating system (heating cable, electric hood), or maybe local hot spots caused.
No directly use heat water& steam, mixed by the nozzle or T-tube, with the help of hot ring-disk, upper to melt. Increasing steam pressure or moisture can generate heat immediately. And pay attention the temperature will not higher than 40℃ when heating.
No withdraw from the partial melting tankers, tanks or reserve tanks. During melting and after melting, materials in
the cylindrical containers should be mixed completely. Ensure the inhibitor well-mixing before the removal of any liquids. Mixture need to be processed through circulator, stirrer or decimator, but not by passing bubbles into MAA.
MAA implosion will produce heat and smoke. If implosion caused, using plenty of water to wash immediately and transfer lateral materials, and other staff must evacuate.
MAA is corrosive. Once stain on hands or clothing, give a well water washing and with alkaline soap. Once touch eyes, wash and see the doctor.
