PER CENT CA8-0-SIL BY WEIGHT

As an agent for thickening any liquid, the addition of a very small amount of CAB-O-SIL to various solvents markedly in-creases their viscosity.

How CAB-O-SIL helps blend particles of different sizes and characteristics

Here's a different kind of silica, that homoge­nizes—makes compatible—particles of varying sizes and chemical characteristics, CAB-O-SIL'S super-fineness — it has a particle size of 0.015 micron — measurably aids in increasing the uni­formity of the product to which it is added. For example:

In a dry state, 0.5 — 1 % CAB-O-SIL keeps lead oxide, salt, sodium bicarbonate and other kinds of caking material in free flow state . . . as a tab-letting agent in pharmaceuticals, CAB-O-SIL as­sures more uniform coating, makes dry-blending easier.

In a wet state, up to 0.1 lb./gal. of CAB-O-SIL improves many paint dispersions and reduces the amount of costly, prime pigments needed... less than 2 parts of CAB-O-SIL per hundred of resin give faster, more uniform coating of dip-coated products. CAB-O-SIL is inexpensive to use; no costly formu­lation or equipment changes are necessary. More than 35 different industries are gaining new sales advantages using CAB-O-SIL.
