Product characteristics

  • 01. Storage

    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.

  • 02. Package & Transportation

    Polyethylene containers (net weight 200kg)or stainless tank.

    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.
