Cab-O-SIl Filler
Details
Cab-O-Sil is a lightweight fumed silica thickening powder that when mixed with resin, creates a thixotropic resin, without increasing its viscosity. The reduced flow of the resin prevents run-off and sags when working on vertical or over-head surfaces. Cab-O-Sil increases the hardness of resin and produces hard, solid parts. Making it ideal for structural bonding, filling and filleting.
Can be used in conjunction with other fillers such as Chopped Fiberglass or Milled Fiberglass for added strength. Cab-O-Sil also acts as a free flow additive of powders and can be used as a reinforcing filler in silicone or organic rubbers.

Product Data SheetResources
- General Use: Mix ratio is 1:2 (filler to resin by volume)
- Reduce runs/sagging: Mix ratio is 1:3 (filler to resin by volume)
- Add filler after adding catalyst to resin.
- Fillers can affect the pot life of a resin, create a small trial batch first to determine how much working time you’ll have.
- Silica-filled resins may be difficult to sand. Consider using Microspheres for areas that require sanding.
