Packing and Storage:
It is generally packed in 200/250kg galvanized drums or 25kg plastic drums. Phenolic resin is thermosetting resin, generally at room temperature will continue to react, so the indicators of the resin will also change with the extension of storage time, especially the molecular weight and viscosity will increase with the extension of time, so it cannot be stored for a long time, should be used as soon as possible; Low temperature storage, transportation should avoid sunlight exposure, keep distance from heat sources. It is recommended to store at low temperature. Valid for 1 month, 2~3 months in winter.
