Presence of water in liquid and vapor form in a package containing metals had always been an unpleasant
subject. Conventional Desiccants partially addressed these problems only if it were used in a right way.
Silica gel is most commonly used desiccant, which attracts and holds water by adsorption and capillary
condensation, allowing Silica gel to adsorb about 25% plus of its weight in water. |

Procedure to Activate Silica Gel :
- Safepack Silica Gel pouch contains 25% of blue coloured granules. Blue colour turns to purple to pink when Silica Gel is partially saturated. It becomes whitish on complete saturation, i.e it has become deactivated.
- Take the deactivated pouches of Silica gel in a tray. Keep the tray at a fixed temperature (115 – 1250 C) for 2 to 4 hrs in a ventilated oven.
- Check the pouch for colour difference. Initially the whitish granules will turn to pink and as time passes the indicative type of granules will become blue in colour.
- The colour change from white to blue confirms that Silica gel is reactivated and ready for use.
- Repeat the same procedure every time so as to reactivate and reuse the same pouch of Silica gel.
Features and Benifits :
- Silica Gel performs best at room temperatures (700 to 900 F) and high humidity (60% to 90% Rh) and will drop the relative humidity in a container down to around 40 Rh.
- Indicating Silica Gel is deep blue colour when it is dry and turns from blue to purple to pink as it becomes saturated with moisture.
- High crush strength and high porosity.
- Remains dry and free flowing even when saturated.
- Chemically inert and Non-Corrosive.
