Our drying materials meet or exceed military specifications for control of atmospheric humidity or moisture in sealed packages and containers. Desiccant is one of the most effective and cost-efficient static desiccants available today.

Desiccant  is especially effective in protecting electronic products such as computers, circuit boards and electronic control components.

DESICCANT products are also ideal for machine parts, photographic and optical devices, medical equipment and diagnostics, aerospace and military products, film, paper and metal, food packaging, shipment and storage, packaged chemicals, and packaging of any hygroscopic materials.

We recommend the small size Silica Gel Desiccant for small personal survival kits, survival kit tins and small survival fishing kits and the large size Desiccant for anything larger.

• Meets FDA specifications for food and drug products.
  

• Provides superior adsorption. Remains dry at maximum saturation.
  

• Silica gel can adsorb 15% of its weight in water vapor in 2 hours.

Silica Gel is cheap insurance for your valuable items.  For this price, how can you not take this extra step to insuring the integrity of your survival kit for years to come.

HEAT ON LOW TEMPERATURE TO RE ACTIVATE

1. Arrange the bags on a wire tray in a single layer to allow for adequate airflow around the bags during the drying process. The oven’s inside temperature should be room or ambient temperature (77-85 deg F.) (A CONVECTION, CIRCULATING, FORCED AIR TYPE OVEN IS RECOMMENDED FOR THIS REGENERATION PROCESS. SEAL FAILURES MAY OCCUR IF ANY OTHER TYPE OF HEATING UNIT OR APPLIANCE IS USED.)
2. When placed in a forced air, circulating air, or convection oven, allow a minimum of 1.5 to 2.0 inches of air space between the top of the bags and the next metal tray above the bags. If placed in a radiating exposed infrared element type oven, shield the bags from direct exposure to the heating element, giving the closest bags a minimum of 16 inches clearance from the heat shield. Excessive surface film temperature due to infrared radiation will cause the GDT-II material to melt and/or the seals to fail. Seal failure may also occur if the temperature is allowed to increase rapidly. This is due to the fact that the water vapor is not given sufficient time to diffuse through the GDT-II material, thus creating internal pressure within the bag, resulting in a seal rupture. Temperature should not increase faster than 0.25 to 0.50 deg F per minute.
3. Set the temperature of the oven to 250 deg F + 5 deg F, and allow the bags of desiccant to reach equilibrium temperature. GDT-II has a melt temperature of ~325 degrees F. (Activation or reactivation of both silica gel and bentonite clay can be achieved at temperatures as low as 220 F).
4. Desiccant bags should be allowed to remain in the oven at the assigned temperature for 24 hours. At the end of the time period, the bags should be immediately removed and placed in a desiccator jar or dry (0% relative humidity) airtight container for cooling. If this procedure is not followed precisely, any water vapor driven off during reactivation may be re-adsorbed during cooling and/or handling.
5. After the bags of desiccant have been allowed to cool in an air tight desiccator, they may be removed and placed in either an appropriate type polyliner tightly sealed to prevent moisture adsorption, or a container that prevents moisture from coming into contact with the regenerated desiccant.
