How to store the two-part gap filler?

A: Unless otherwise indicated on product data sheets, two-part Gap
Fillers should be stored in the original sealed container in a climate
controlled environment at or below 25°C and 50% Relative
Humidity. If stored at reduced temperatures, materials should be
placed at room temperature and allowed to stabilize prior to use.
Unless otherwise noted, all cartridges and tubes should be stored
in Bergquist defined packaging with the nozzle end down.
