Silica Gel - FAQ

Uses for Silica Gel; Problems solved by Silica Gel protection.

Most damage to stored valuables and supplies is caused by humidity trapped within the enclosed storage area itself ... be it a safe, gun, camera or telescope case, video tape or photograph collection, computer parts and accessories such as CD-ROM cases, tool box, storage container, display case, shipping container, locker, silver drawer, whatever. Humidity trapped within enclosed space turns into almost imperceptible condensation which causes irreparable damage:

rust, corrosion, oxidation, tarnish of tools, electronic, computer and other valuable equipment, coin collections, silverware
mildew, fungus, mold, odor, spoilage
spotting, toning, stains, gum damage, cracks to stamp collections and valuable documents, photographs, videos
shortened "shelf-life" of photographic film, batteries, fogging of lenses
deterioration of foods, medicines, etc.

Silica gel prevents these moisture related problems before they begin. (Manufacturers know this. That's why they often include a small packet of silica gel in shipments of new guns, cameras, electronics, leather goods, pharmaceutics, etc.)
Silica gel creates a protective shield of dry air within any enclosed storage area.

What is Silica Gel; How does Silica Gel work?

Silica gel was developed just prior to WWI and was used in Allied gas masks; then, in WWII it was used extensively to keep penicillin dry. It remains the highest capacity adsorbent available today. Not a "gel" as commonly thought of, and not to be confused with "silicon gel", silica gel is a porous, granular form of silica, synthetically manufactured from sodium silicate.
The internal structure of each small silica gel granule is composed of a vast network of inter-connecting microscopic pores, which attract and hold moisture by a phenomena known as physical adsorption and capillary condensation. (It sounds ridiculous, but a single teaspoon of Hydrosorbent Silica Gel has an internal adsorptive area equivalent to a football field, including the two end zones.) Hydrosorbent Silica Gel is inert, non-toxic and safe to use to protect foods, medicines, sensitive materials, electronics, films, etc. Even when saturated with adsorbed moisture, silica gel looks and feels dry to the touch.

Hydrosorbent Silica Gel can be reactivated indefinitely. Each Hydrosorbent Silica Gel unit has a built-in indicator which turns from blue to pink signalling when the product is saturated with moisture and needs reactivation. Once saturated with moisture, silica gel can be easily reactivated in a conventional oven for lifetime protection.
Since World War II, silica gel has been the desiccant of choice by government and industry.

How to prevent condensation & excessive moisture in container ?
Use Desiccant

WhyCarewell Desiccant... ?
Since it is made of special clay , environmental friendly and can absorb moisture up to 50 % of its dry weight.

How it works ?

After the container doors have been closed , Carewell Desiccant controls humidity inside the container through continuously adsorbing the moisture from the enclosed air. Our desiccant is designed to hold the moisture and not release it back into the container's climate.
