How do I create an epoxy compound with fillers?

Homebrewing your own epoxy compounds instead of using the SilverTip line of ready-to-use epoxy compounds involves mixing various fillers into a mixed batch of one of our liquid epoxies. Below are some guidelines for creating common compounds using System Three General Purpose Epoxy, Cold Cure, SilverTip Epoxy, Clear Coat, and SB-112 Liquid epoxies.

Adhesives:

1 cup of Silica Thickener to 6 Oz of mixed epoxy. 

or

3/4 cup of Wood Flour to 6 Oz of mixed epoxy.

Fairing Compound:

1/2 cup of Silica Thickener + cup of Glass Microspheres to 6 Oz of mixed epoxy. 

Filleting Compound: 

1 cup of Wood Flour to 6 Oz of mixed epoxy.

Playdough like Putty:

3 cups of Glass Microspheres to 6 Oz of mixed epoxy.

 

For further detail on mixing and applying compounds, please refer to the literature linked below.
