What ratio of dye should I add to the HXTAL?

It would depend on the intensity of the color you need. We recommend mixing Orasol with Part B of HXTAL as Part B is the thinner viscosity of the two parts. Mix your Orasol and then use a fine mesh filter to filter your Part B to make sure you get any chunks of dye out of your Part B before using it.

Remember that Part B is only one part of the four parts of the mixture, Part A is three times as much material so your color will thin out when mixed with Part A.

A small amount of Orasol goes a very long way though. It is quite intense coloring.
