Most diatomaceous earth-based carriers look like this under close scrutiny. But now there's Hi-Sil® ABS. A pure, consistent precipitated silica from PPG. Traditional carriers for viscous liquids are made from the skeletal remains of fossilized diatoms—prehistoric, micro­scopic plants—mined in California.

Hi-Sil® ABS, on the other hand, is a truly synthetic precipitated silica. PPG Industries manufactures Hi-Sil ABS under very strict process controls. So you can count on Hi-Sil ABS for con­sistency and purity. Right down to the microscopic level.

Hi-Sil ABS is dispersible. Its pure white color allows for excellent color control. It can carry compounds of up

to 75% active ingredients. And as an added bonus, Hi-Sil ABS offers equiv­alent reinforcing properties to the Hi-Sil 200 series of reinforcing fillers.

In short, Hi-Sil ABS from PPG is a superior carrier. Because it's manufac­tured. Not mined. And you can get it fast from our plants in Lake Charles, Louisiana and Barberton, Ohio.
