Chemical that prevents recasting resin parts?

[Fetthunter]

Hey guys! I remember a thread awhile back that discussed a chemical that can be applied topically after curing that prevents others from recasting your resin pieces. This chemical causes the silicone (being used to make a mold of your resin piece) to stick to the resin, thus forcing the recaster to cut the cilicone off of the resin to retrieve the part (and thereby destroying the new mold). I couldn't find the thread...

Any ideas what I'm trying to think of, or am I just imagining this? :confused



Thanks!

You can soak it with silicone spray but keep in mind this will also make painting it virtually impossible too, bit lame really.

I saw an auction recently that mentioned that an item was cast with resin made with a secret recipe that included a cure inhibitor to prevent recasting. I have no idea if the claim was valid though....

dusting the mould with sulphur apparently stops some silicones from curing not all though.

Sulfur sounds familiar... In my experience, Sulfur-based clays prevent Silicone from curing, which would be an acceptable solution also. This chemical that I was thinking of didn't prevent the Silicone from curing, and actually caused it to cure AND adhere to the resin.

Hey, whatever works, right?

Upon further research, it does appear that Silicone on the resin piece makes freshly poured Silicone stick to it, and Sulfur does the opposite and prevents the Silicone from curing... :thumbsup

Now to devise a plan...


Thanks, all! :cheers

Ah, but what if it's painted before it gets casted? Or wouldn't either of these screw up any painting someone might want to do with it?

I think Silicone WILL mess up paint, so I wouldn't go that route. I might be inclined to try the sulfur, though.

The parts in question would be sold unpainted, and in my mind, most recasters would go straight to trying to mold them without painting them first... I don't think sulfur will react with most paints.

I found a place online that sells 1 pound of Sulfur powder for $4.55, so I might try to cast a part with the Sulfur in the mold, and then try to mold the cast, and then try to paint it - just so that I can see what effect there is on the molding and painting processes.

Wouldn't sulfur really stink and be a health hazard if the resin piece was a mask?

Rubbing a prop down with the unbaptized fat of a newborn child will prevent someone from casting it, too.

Dude.

If someone wants to cast your stuff, they'll cast it. Period.

Still pretty pointless i think as there are any number of silicones out there that will still cure with sulphur and even if they happen to try and mould it with one that sulphur does affect all they will need to do is clean the gunk off and give the part a coat of sealer before moulding it again.

Not to mention that I don't think too many people will want to wear a mask or helmet that smells like rotten eggs.

PURE Sulfur is in fact odorless. The "smell of sulfur" usually refers to either the odor of Hydrogen sulfide, for example, from rotten eggs, or of burning sulfur, which produces Hydrogen dioxide, the smell associated with burnt matches. (Wow. I think those high school Chemistry classes just kicked in! :lol). As long as nothing catches on fire, there won't be any "bad" smells, and if something catches on fire, I'll have bigger problems to worry about!

I'm realistic, and don't expect to thwart every recaster out there, but if I can deter a few of them (or at least frustrate them a bit), I'll be happy.

I hear you, recasters are scum.

the only sure fire way i have found about not getting parts recast is not selling them in the first place. unfortunatly

good luck with your experiment

 

[zorg]

well if the recasters got wind of your scheme all they need to do is stick a coat of primer on it and away they go.

And hey, what if you're selling to a person who just wants to paint it and put it on a shelf? Aren't you potentially sabotaging their work here?

 

[Westies14]

Most people would wash it before painting or casting anyhow... It's sad, but recasters are hard to stump. Best of luck!

Someone over at The Clubhouse is working on a formula that won't affect paint, but will ensure that the pieces can never be re-molded.

And how will that work then ? if the stuff doesn't affect paint then the recaster will just prime and seal the piece and drop it in rubber, much like the sulphur thing.

I didn't get all the details, but it worked through the paint and affected the silicone, but it didn't damage a paint application or make it not dry or weep later. He's still working on it to perfect it.

I'll see if I can find the thread and link to it, so you can read it for yourselves, as I'm not sure I'm relaying things correctly.
