    Hey,

    I don't know what colorant is sold in Canada, but adding acrylic enamel, or tree hugger Kool-Aid (waterborne) material will make a big mess of your epoxy. Perhaps you can contact TCP and purchase some colour to mix in with the white?

    dont know what you are working on, i used crystal clear resin to cast my own taillights for my caddy!
    i had a lot of trouble finding the right colordye, but i also needed a transparent color. its also urethane resin, and different than you epoxy. but i tried many different types before i found the real one! thanks to Matt townsend!

    sometimes Engilsh/USAlish/Australian gets confusing, so hopefully this will help.......if I use "araldite" (a clear two part epoxy) I use fiberglass colours. Anything similar to fiberglas resin or epoxy resin we have here can be coloured with the fiberglass colours.
     
  7. well this went off track...lol I am talking white epoxy primer sealer, to spray over bare metal, before body work....sorry for the mix up

    ah ha, ok with 2k primer I use 2k colour, there should be a matching "epoxy" paint colour you can use. I only do this if i have dark colour over if your painting it white you have the perfect base :)
     
  9. Having been involved in the paint industry I can assure you mixing universal tinting color in epoxy will come back to haunt you,,as it dries there is a reaction that will cause the tint to spot and not completely dry. HRP

    Agreed. You are playing w fire a little here. 2k epoxy can be fussy enough without adding things that don't belong.

    I would just talk with your paint distributor/mixer and go by their recommendations.

    works for me , have some here 20 years old still good, but I use tinter or coloured paint that is the same composition as the primer so thay would be acrylic tinter for acrylic primer or 2k colour for 2 k primer, I dont mix brands or types,
     
  12. ok, thanks...never used epoxy.. I will email TCP and order some color...
     
  13. PPG makes a product in the commercial coatings division called CRE it's a dtm epoxy primer that is tintable and sands awesome, high build also.

    Having sold architectural and industrial coatings for 30 years by a variety of companies, for two component epoxies and urethanes, we used alkyd based colorants to tint with. Not knowing exactly what you are using, take my two cents for it's worth.

    I used to use House of Kolor Kandy concentrates to tint Dupont Corlar ( an epoxy primer).
    You could add so much, and the color wouldn't get any darker. You'll only get pastels.

    If you're going to tint TCP white epoxy (betting it's relabeled Shop-Line) you can indeed ad a conservative amount of toner for base colors. The trick is to reduce both with a proper solvent (like Shop-Line 506) and only do it to the last coat. Epoxy reduces with basecoat reducer to be used as a sealer and I've yet to have a single failure. I also tint a final reduced coat of surfacer about 50% with some black tint added as well. Makes for a bitchin guide coat:cool:

    ppg dp 40 is green gray
    i have also mixed different colors of epoxy to make other colors, dp 90 and dp74 mixed gives you an old school brown primer look.

    I've been told that only Sikkens brand primer/sealer should be custom tinted to create your own color.
    If you add tint to other brands of primer/sealer, you can only add a tiny amount before it affects the adhesion and can lead to failures since they were never intended to be tinted.
    Sikkens on the other hand can be tinted quite dramatically. I have custom tinted Sikkens primer/sealer on my car for many many years with no issues.
     
  27. Why dont you shoot a candy over it, you can even thin it out so its a lot more opaque
