3D Transfer: Acetate and release agent

Hi everybody,
Is there a specific release agent to coat acetate used during a 3d transfer procedure?
I don't use a "dedicated" acetate sheet, so i need to use something to allow the bondo appliance to stick-out from the acetate when the transfer paper is attached to the piece.
I tried with some release agents like Vaseline, silicone based spray etc but the main piece does not leave the acetate.

Attached: a pic  about the problem

Thanks,
Mauro

    Great to know for when I start learning how to make molds :)

    Got some PVA and making some test.... will let you know.

    Hi all,
    from the first test with PVA, i noticed that if i wait more than 12 hours before peeling off acetate, the application does not leave the acetate.
    Instead, if i complete all the procedure in about one hour, everything is fine.
    So it seems that actually i can't prepare pieces to apply in the future.
    I'm sure that i make mistake somewhere. Anyway I'm going on with tests.
    A note: having some big differences in acetate behavior (in terms os releasing property) when i use PVA with brushes or airbrush.
    Will let you know.
    thanks

    Awesome. I was in the same situation, but I tried Mann's Ease Release 200 (General Purpose Mold Release)  lightly coated on the acetate but the pros-aide piece managed to weld itself to the acetate.
    I'll find some PVA and airbrush it to the Acetate and report back.

    Side Note:
    Has anyone else had their pros-aide piece develop hairline cracks as if it were drying out too much?
    It removes from the Mold Star 30 mold cleanly with little to no release but it's not very sticky. I tried rubbing the piece to the decal paper and it would not stick at all, even with a light dabbing of pros-aide right from the bottle...

    I'll keep at it!

    JUST A NOTE :
    during my experiments, i tried also inkjet printing acetate and i have been surprised to notice that it simply works. The sharpie does not bleed but the acetate sticks out from the transfer paper and transfer piece nicely.

    Anyway I'm sure that PVA is the final solution if not using dedicated self-releasing acetate.

    @Michael Effen:
    i have some shrinkage too and after some time the piece tends to crack too.
    i guess it's normal but i also think that most depends on the bondo's density, i mean, less thick should crack less... just try out and let me know if you like.

    I don't know if you're doing this or not, but using canned air to flash freeze the appliance can help get it off by stiffening the bondo.

    You're right, I made some new PTM and used less cabosil. No cracks and much more sticky out of the mold. I'm also trying your Inkjet transparency idea, having had a box lying around. I have decla paper, too but I feel like the film that comes off as well degrades the piece. I suppose once adhered you can wash that off. 

    My tests coating acetate with PVA has been mixed. Pulling the piece from the freezer causes some condensation which makes the PVA gummy immediately and a mess to pull from the mold. Also, PVA coated photo paper (used for the glossy finish) didn't release the piece either. Unless I can find a better paper, I'm going back to the decal sheet and practicing until perfect.

    Fun fact... it was 18F below last week and I could just set my molds out on the porch and they polymerized faster than my freezer!

    So here are my results: PVA is a bust - either gums up the prosthetic or doesn't release from the acetate. Went back to Mann's 200. Decal paper - transfers a huge glossy, plastic sheet covering the prosthetic. I've dampened a piece and pulled the glossy surface and left enough 'water soluble release' to let the piece slide. Will update if any of this actually works.

    Tried parchment paper but the moisture wrinkles the paper and then won't let go. Overall pretty frustrating... but this is how you learn it seems. Trial & Error & Error & Error :)

    hi Michael,
    it seems we are having all the same situations and problems.
    From a point of view I'm "happy" because it does mean that I'm not alone !!

    I also tried a special parchment paper that is double sided-siliconed coated but as you mentioned, wrinkles are boring and don't let a flat, even surface to be created.
    I'm pretty sure that PVA works if coated with airbrush instead of a normal brush but you must use the appliance in short time because after 24 hours acetate wont release bondo easily.
    Using a tattoo acetate allows to use the appliance in time (if we don't mind the natural shrinkage of the appliance itself).
    My goal is to use food acetate, coat with something and then use decal transfer paper with it.
    In my case, that would the cheapest recipe to prepare amount of  transfer appliances to use in my needs.
    Now I'm thinking to purchase an airbrush set :)
    I noticed that on the transfer acetate and paper i tried out, there is a thin layer of some kind of adhesive that releases itself if used with temporary tattoo.
    This thing encapsulates the printed tattoo. Using this kind of transfer kit, encapsulate the bondo appliance too.
    If I remove this thin layer from the acetate, it allows a good releasing property as well... so i guess that there must be a product to coat acetate.
    Sorry, messy thoughts but this is my troubled experience with this process...
    I trust Mr. Berger, so I think i will proceed on the PVA direction... let's see...

    No Maurio, you're not alone! 

    I'd set the process aside for a while, but in another project I found that I have transfer paper used for vinyl cut decals, and that leaves a thick, waxy release paper as waste product. It's opaque, but I think it will release the transfer material. I plan to test this tonight.

    Back to the decal paper, I've tested pulling an entire sheet of the glossy print medium off, leaving a full 8.5x11 sheet of paper that transfers a prosthetic very very well. It's going to be my go-to material. I recommend it to anyone trying this process.

    One last experiment Maurio: try using plain acetate with a thin coating of petroleum jelly as the release. It's the best solution so far and can be cleaned off with soap and water once applied to the model. 

    I'll keep experimenting. I feel like the only acetate solution will be a purpose, coated silicone release sheet made just for this.

    What do you guys use as a release for the silicone mold. My PTM material isn't releasing properly from the silicone

    hi Josh,
    i've tried all these : 
    -silicone based release agent (spray)
    -vaseline based release spray
    -vaseline (gel)

    my fav is simple vaseline gel, just a little amount, rubbed with a finger in a very thin layer all over the mould and then cleaned a little with a piece of soft fabric.

    let us know ,)

    hi everybody here,
    today I've got some silicon paper from Vittorio Sodano's shop.
    I'm planning some test.
    The paper is coated with silicone release agent (one side only)
    It seems that the release agent is so slippery that the appliance does remain on the mould !!??
    So I think to coat the main mould with any release agent too just before casting bondo into it.

    in progress...

    Thank Mauro I used the Silicone release (Brush on) works real well and cleans easy theres very little to clean off the finish product. Thank you for your help

    Just an update:
    I'am testing a silicone-based spray, normally used to make object waterproof (camp-tents, fabrics ecc.).
    well, it seems to work.
    I am using 2 or 3 coats of it on standard acetate sheets, letting dry between each pass.
    Still far away to have found a final solution.

    Awesome, I'm curious to see how that works.
