The Challenge of
SANTOCEL Chemically inert, incredibly light, extremely porous. One pound's surface area is over 17 acres. A cubic inch has 5 0 0 billion particles. What can you do with this unique material?
SUCK THE LIQUID from w e t silica gel. Hold the pressure so the structure doesn't collapse. Infuse air. You've got silica aerogel. Monsanto calls it
What can you do with it? Add Santocel to varnish or lacquer. You dull the sheen. Put a little Santocel with DDT. Now you can dry-grind t o less than 1 micron \vithout clogging. Put even less Santocel in stored grains. You'll kill beetles and weevils. Body a paint-remover paste with Santocel. You'll clean cleaner and faster. Add Santocel to a heavy metallic based paint. You keep the pigment from settling out. 654

"Santocel." Structure seen in electron photomicrograph shows how particles agglomerate together to give Santocel its unusual properties.
Use Santocel in a molded brake lining. You protect it from heat, give it extra long life. Use Santocel to insulate a freezer. You hold in the cold, save 50% of normal insulating space. Or, you can use Santocel: To thicken polyester or epoxy resins. As a reinforcing filler for silicone rubber. To control viscosity in making printing inks. To thicken hydrocarbons to make greases. To reduce stringiness in rubber cement. Or . . . why don't you make the next move? Phone your local Monsanto repre-
