I am trying to dye an epoxy adhesive which I use to glue Plexiglas. I tried with different commercial epoxies and normal ink (I dont have a clue what the chemical composition of ink is), however with 2 out of 3 epoxies the mix turnes redish, with only one it stayes kind of blueish.
Can anybody help me which dye to use with epoxy? I just want to be able to distiguish between the adhesive and the Plexiglas in the end, so I actually dont care if the hole stuff turns red instead of blue, however it seemed that the redish epoxy does not cure perfectly ....?
Thank you for your help
