Silica gel is a reusable desiccant which can be used to lower the relative humidity of an enclosed environment to below 40%. This is effective at preventing forms of moisture damage such as mould, condensation & rust. In ideal conditions, silica gel can adsorb up to 40% of its weight in moisture before reaching its adsorption capacity and requiring replacement or regeneration. Silica gel is non-deliquescent, so even when saturated with moisture, its outer surfaces stay dry and remain in a solid form.

White silica gel beads do not contain a moisture indicator, like orange or blue indicating silica gel, so it is more difficult to determine if they’ve become saturated. However, since silica gel becomes heavier as it adsorbs moisture, you can weigh the amount before use and check the weight regularly. Once its weight has increased by approximately 30%, the silica gel should be reactivated or replaced as it is close to saturation.

Humidity indicator cards can also be used to keep track of the relative humidity of the sealed environment. When the card begins to read a higher humidity, then you know the silica gel has stopped working due to saturation.

Features

  • Packaged in resealable bag or pail (depending on chosen weight)
  • Lowers relative humidity in enclosed environments to 35-40%
  • Prevents moisture damage, such as condensation, mould & rust
  • Adsorbs up to 40% of its weight in moisture before reaching its adsorption capacity
  • Beads stay dry and remain free-flowing, even when saturated with moisture
  • Reusable; easily regenerate by heating in any standard oven
  • Non-corrosive with a low dust emission rate making it safe for use with sensitive items
  • Inert, odourless and non-toxic


Applications

  • Gas drying
  • Electrical enclosures
  • Electronics
  • Non-consumable packaged items
  • Double-glazed windows
  • Mining industry
  • Aerospace
  • Laboratories


Reactivation Instructions

  1. Spread the silica gel on an appropriate metal or glass oven-proof tray – try to keep the silica gel layer to a thickness of less than 2 inches (5cm).
  2. Place in a 115°C -125°C oven for approximately 3 hours.
  3. Once reactivated, remove from the oven and leave out until cool enough to handle.
  4. Store in a sealed container until ready for use.

very happy

By: on 6 November 2020
just arrived today, havent used as yet (don't expect any problems - it is only gel) it arrived quickly (express post) and very well packaged - the beads packet was even bubble wrapped (how awesome is that) - was so impressed, had to leave a review - would not hesitate to buy again, but i don't expect i would need to (as i can dry them out again in the oven). :D
