2 Page 2 Consider the following… "Aerogel is predicted to be one of the most important materials of the 21-century.” TAASI Corporation has developed a range of engineered Aerogel materials for commercial applications under the trade name of Pristina™ Aerogels.

3 Page 3 What is an aerogel? Aerogels are advanced man-made nanophase materials, having high porosity and surface area, varied chemical structures, and fascinating useful properties. Thus, Aerogels are materials with a vast potential for improving our daily lives. Features of Aerogels Lowest solid density Highest porosity Very high surface area Low dielectric constant Low refractive index Versatile compositions

4 Page 4 How are Aerogels formed? An Aerogel is formed when a wet sol-gel upon drying, releases entrapped liquid while maintaining a gel structure, thus resulting in a highly porous, air-filled gel. Aerogel was first prepared over 65 years ago by Samuel Stevens Kistler, and although this was an extraordinary scientific achievement, industry found it troublesome to work with Aerogel based on its fragile form. Aerogel was also difficult to market commercially because of a cost limiting process. Page 4
