F-Series colours have been developed with special-FX artists, silicone sculptors, and doll artisans in mind. They contain a higher concentration of pigments than either the M-Series or LY-Series resulting in faster coverage and stronger, more opaque colours. When diluted with the appropriate solvent (such as toluene, xylene, or naptha) the F-Series is excellent for airbrushing.
F-Series Silicone Paints
F-Series paints are sold in 2-part "kits". When using FuseFX paints you mix an equal amount of "Part A" and the chosen colour, then apply as desired to the surface of your cured and clean silicone piece (to prevent loss of details you can also "backpaint" colours into a released mold before filling with the bulk of your silicone).
Each standard bottle "kit" contains a total of 1 oz (30g) of silicone (15g of colour and 15g of part "A") and can cover an area of over 10 square feet when applied in a stipple fashion. A little goes a long way...
You can even custom blend your own colours by combining different colour "parts" before catalyzing with an equal amount of Part "A"!
