Materials
MGS 335 Epoxy
The MGS 335 Epoxy should be mixed at a 100:38 resin:hardener ratio. This means the following:
Total Epoxy | Resin | Hardener |
---|---|---|
60 g (~2 oz) | 43.48 g | 16.52 g |
120 g (~4 oz) | 86.96 g | 33.04 g |
180 g (~6 oz) | 130.43 g | 49.57 g |
240 g (~8 oz) | 173.91 g | 66.09 g |
Don’t try to mix more than 8 ounces (~240 g) in a batch. If your layup requires more than 8 ounces, make multiple batches. Mix enough epoxy for a 3:4 ratio of epoxy to fiberglass by weight (that is, mix 75% as much epoxy as fiberglass by weight).
Slurry, Wet and Dry Micro
Mix the glass bubbles with already-mixed epoxy.
Material | Desired Consistency | Ratio (Balloons:Epoxy) (by volume) |
---|---|---|
Slurry | Almost same as epoxy | 1:1 |
Wet Micro | Sags or runs like thick honey | 2-4:1 |
Dry Micro | Paste that does not run or sag | ~5:1 |
Apply Dry Micro with a putty knife. Apply Wet Micro and Slurry with brushes.
Flox
As with Slurry and Micro, mix the flocked cotton with already-mixed epoxy.
Material | Desired Consistency | Ratio (Cotton:Epoxy) (by volume) |
---|---|---|
Flox | Just enough to make the mixture stand up | ~2:1 |
Wet Flox | Sag or Run |
When using flox to bond a metal part, be sure to sand the metal dull with 220-grit sandpaper. Also paint pure epoxy (no flox) on the metal part prior to bonding with flox.
