Hydrophobic Silica Disc

for experimentation

Hydrophobic Silica aerogels are specially formulated to repel water and to not absorb moisture from the air.  Where Classic Silica tends to shrink and cloud in humid environments, Hydrophobic Silica retains its transparency and integrity.  Floats on water without damage!  Excellent for applications involving absorption of hydrophobic substances such as oil.
