Abstract

An improved aerogel and a process for production of the same. The improved aerogel which has a significantly reduced dust (e.g., aerogel fines) and static charge, as compared with conventional aerogel products. The aerogel also has a “sticky” or “tacky” nature which can be used to attract any available dust, fines and/or particulate matter and also restrict flowability of aerogel granules, for example, out of a breached container and thereby minimize loss of the aerogel product through any breached opening.
