Resin & Coating Raw Materials
Methacrylic acid is an important organic chemical raw material and polymer intermediate. MAA is formed via the acetone cyanohydrin (ACH) route to manufacturing 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.

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.

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.
