The Surfboard Studio Cab-O-Sil Fumed Silica

The Surfboard Studio Cab-O-Sil Fumed Silica 1.25L Tub

Cab-o-sil is a filler we use for adding into resin when setting plugs and boxes, its super light weight and super strong and makes the mix nice and thick. It creates a super strong bond between the foam and the plugs.

Fumed silica Hydrophilic  consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high surface area. Its three-dimensional structure results in viscosity-increasing, thixotropic behaviour when used as a thickener or reinforcing filler. Fumed Silica is ideal to be used as a filler for glueing, compatible with polyester, vinylester and epoxy resins.
