Product as expected. Much better than the stuff I got from the big A- less clumping and easier to mix.

Cab-o-sil is a known product to us since our university days when we worked on conductive elastomers for the US Navy. Its made by Cabot Chemical out of Boston so you know its an excellent product for thickening solutions and epoxies or as an anticaking agent. Wouldnt use any other brand of fumed silica Cab-o-sil continues to be tops.
