How does silica gel remove moisture?

Silica gel is a desiccant that can hold 30 to 40\% of its weight in water. Each silica bead has many tiny interconnected pores, resulting in high surface area. The tiny pores also hang on to moisture through capillary condensation, which means that, even when saturated with moisture, the beads seem dry.

How long does it take for silica gel to work?

Activated clay, silica gel, and molecular sieves can all absorb approximately 10\% of water when exposed to 25°C/75\%RH for 1 hour. Silica gel’s high specific surface area (around 800 m2/g) allows it to adsorb water readily, making it useful as a desiccant (drying agent).

What Colour is silica gel?

The three most commonly available colors for silica gel are white, blue indicating and orange indicating. Indicating silica gels are processed with moisture indicators that change color to show when the product is saturated and needs to be regenerated.
