It is advised to refrigerate COR on arrival, at or below 5 °C (the temperature of most common refrigerators). Keep COR cold for long term storage. COR will solidify when cooled, and needs to be warmed to a homogenous liquid solution before printing.
The shelf life at room temperature is approximately one week. If you are actively using COR throughout the workday, you do not need to refrigerate in between prints.
Our recommended workflow is to put COR in the refrigerator at the end of every workday, and follow the thawing instructions on the Pre-Print Prep page each morning before printing.
