Technical Specifications

• Material: High-purity Silica Gel ($SiO_2$).

• Indicating Agent: Cobalt Chloride (provides the deep blue color).

• Unit Size: 2lbs (Approx. 900g) Resealable, Air-Tight Container.

• Bead Size: 2-4mm spherical beads (optimized for airflow and surface area).

• Adsorption Capacity: Up to 35-40% of its own weight in water vapor.

Key Features & Benefits

• Visual Status Indicator: The beads change color from Deep Blue (Dry/Active) to Pink (Saturated/Inactive), allowing for instant inspection of the environment’s humidity levels.

• Rechargeable & Reusable: These beads are highly economical. Once they turn pink, they can be “recharged” (driven back to a dry state) by heating them, restoring their blue color and adsorption capacity.

• High Porosity: Engineered with millions of microscopic pores that trap moisture through physical adsorption rather than a chemical reaction.

• Dust-Free & Durable: High crush strength ensures the beads do not break down into dust, making them safe for use near sensitive mechanical parts or optical lenses.

Applications

• Industrial Air Drying: Used in compressed air dryers and breathers for transformers or hydraulic tanks to prevent internal corrosion.

• Electronics Protection: Ideal for protecting PCBs, camera gear, and laboratory instruments from humidity and fungal growth.

• Safe Storage: Perfect for long-term storage of metal components, preventing rust and oxidation.

• Flower Preservation: Widely used in botanical and craft applications for rapid, even drying of floral specimens.

Recharging Instructions

To reuse the beads, follow these heat-activation steps:

1. Spread the saturated (pink) beads in a single layer on a shallow, oven-safe tray.

2. Heat in a ventilated oven at approximately 105°C to 120°C.

3. Heat until the beads return to their original Deep Blue color (typically 0.5 to 2 hours depending on volume).

4. Allow to cool in a sealed container before returning to service to prevent immediate moisture re-adsorption.

Safety & Handling

• Safety Note: Blue indicating silica gel contains Cobalt Chloride. It should not be used in direct contact with food or pharmaceutical products (for those applications, we recommend our Orange Indicating or Non-Indicating silica gels).

• Handling: Wear gloves and avoid inhaling dust when handling large quantities.

• Storage: Always keep the container tightly sealed in a cool, dry place when not in use to maintain shelf life.
