Aerosil-Cabosil

(Fumed Silica) ( Aer-o-sil 200 )
Net Weight: 2oz/qt
Thickening agent for epoxies, polyesters, and urethanes. Thicken resins to your own taste by adding varying amounts. Ideal for making adhesives and putties for gluing wood, fiberglass, stone, concrete, etc. However, adding this product will make the cured resin much more difficult to sand.

(rule of thumb for purchasing: 1 quart of resin will need about 1 quart of Aerosil to make a mayonnaise like viscosity)
