Packaging and storage: Generally, it is packed in 200/250kg iron drums or 25kg plastic drums. Since phenolic resin is a thermosetting resin, it will generally react continuously at room temperature, so the various indicators of the resin will change with the extension of storage time, especially the molecular weight and viscosity will increase with the extension of time. It cannot be stored for a long time and should be purchased and used immediately; store at low temperature, avoid sunlight exposure during transportation, and keep away from heat sources. It is recommended to store at low temperature. The validity period is 1 month, and 2~3 can be stored in winter.
