When mixed into liquid resin, Cabosil functions as a
resin thickener (flow control agent) and sometimes as an
anti-settling, anti-caking agent. Its applications are
many, including thickening paint, dyes in the screen
printing industry, epoxy, polyester, urethane, water,
hand soap and shampoo. It is a versatile thickening
agent that has even been used to "thicken" fresh water
and sea water.
Cabosil is an extremely fine particle size silica
(silicon-dioxide / SiO2) aerogel. It is pure white and
free-flowing. Each volume contains about 94% dead air
space, with a density of only 2.3 lb/cu ft. On the other
hand, water (density 62.4 lb / cu ft) weighs about 27
times more.
This thixotropic agent holds the liquid resin in
place until the curing agent takes over and hardens it. |
