Can food coloring be used to color Alumilite casting resins?

No, food coloring is a water based dye, therefore is not compatible with our resins. Alumilite dyes are fully reactive and will not bleed after cure unless die is not mixed in with resin fully. Oil based or alcohol based dyes also may work. Another option for coloring/tinting resins in to use Alumidust. They can be applied to silicone molds prior to casting or mixed in with resin.
