What is the HYDROSORBENT PRODUCTS - 40 Gm. Silica Gel?

One of the most effective moisture absorbers ever developed. These man-made crystals prevent rust, mildew, corrosion, and tarnish before they start by literally "sucking up" and safely holding the moisture that causes them. Yet, the crystals stay dry to the touch, will not harm or dampen any surface even when saturated. When built-in indicator changes from blue to pink, the crystals have all the moisture they can hold, and are easily reactivated by heating in a conventional oven for 3 hours. The crystals can be reactivated over and over again, giving you a lifetime of protection from the destructive effect of dampness. Gives longest time between reactivations when used in enclosed areas and containers. Perfect for tool chests and lockers, closets, safes, etc., to protect guns, cameras, silver, clothing, documents, leather, medicines, electronics and tools. Several boxes may be used together for large gun cabinets and chests, closets, darkrooms, boat lockers.


SPECS: 40 Gram protects 3 cu. ft. - one drawer, individual gun, or a camera. 2" (5.1cm) x 4" (10.2cm) x 1/2" (1.3cm) flat aluminum can. 450 Gram protects 33 cu. ft. 7" (17cm) x 4-1/2" (11cm) x 2" (5cm) corrugated carton. 750 Gram protects up to 57 cu. ft. 6" (15.2cm) high x 4" (10.2cm) dia. steel can. 900 Gram protects 66 cu. ft. 6" (15.2cm) x 3" (7.6cm) x 8-1/4" (21cm) corrugated carton.

Great to keep products free of moisture and when window changes color it can be re-activated in your oven.

Just right!
The 40g version comes in a nice, thin, aluminum container with lots of small holes for air circulation, and a window so you can see when the color has changed to pink, indicating the pack needs to be put in the oven and dried out. These are just right for putting in a sealed Pelican gun case (or similar) to keep the internal humidity level down.

Great stuff
I store all my ammo in 50 cal and 40mm ammo cans. I started off just protecting surplus ammo with these little packs, and then expanded to ammo in fiberboard packs, and now I protect everything with 2 packs in each can which I change twice a year wither then need it or not. I've some packs that I've recharged a half dozen time with no problem. I keep the recharged packs in an ammo can until I need them.
