Product Information:

System Three silica thickener is an extremely fine powder used to create a very smooth, non-sagging, high strength mixture. This material is also referred to as colloidal or fumed silica, and is an excellent thixotropic agent which is used to control the viscosity of mixed epoxy systems. Silica can be used alone for a very smooth, non-sagging, high strength mixture or combined with fillers or fibers to make them non-sagging. A 5-quart quantity of silica thickener when combined with 1-gallon of mixed epoxy/hardener, will produce about 1.75 gallons of a non-sagging firm paste.


  • System Three adapts to any application
  • Gained wide acceptance in the wooden boat building and repair industry
  • An extremely fine powder used to create a high strength mixture

    Comments about System Three Silica Thickener, 5 Quart :

    ~I used this to help keep a gel coat from running down the sides of a baptismal pool. ~I used it with 300/21 epoxy from AeroMarine products, a cycloaliphatic non-blushing clear epoxy. Constant indoor 70 degree and 50% humidity conditions during use. ~It did not white out with this epoxy but stayed very clear. ~It HELPED the gel coat not to run, but even at a very thick ratio (difficult) it ran pretty bad on the second coat. Perhaps stay with a lighter mixture and then you'll be able to put a thin-enough coat on that it will not run on vertical surfaces.

    Comments about System Three Silica Thickener, 5 Quart :

    I've used this product as a component of of epoxy, fashioning whole structural elements in which the original wood was long gone. Works great - solid, mill-able, sand-able and paint-able. However! My best discovery is as a thickening additive to oil-based finishes for use as a grainfill. At approx. 3:1, silica:finish volume ratio, it makes a smooth, clear, spreadable grainfill that perfectly blends with finish topcoats.
