OCTOPUS FLUIDS RESIN INKS are highly concentrated inks specially developed for colouring all common brands of casting resins. It is particularly suitable for epoxy resin, UV resin, acrylic resin and polyester resin. Due to their extremely high content of colourants, they are much more productive than conventional alcohol inks and can therefore be used extremely sparingly. This means that both the mixing ratio and the heat resistance of the resin remain unaffected.
