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
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,
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
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
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 ?
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.
