Resin Addict Forum

Hello there, nice to meet such a great, helpful community over the casting and molding projects!
I am a bit amateur, having experience only by molding small equipment parts with polymorph (instant mold) and green stuff/milliput.

I am willing to try rubber and resin. I am going to start playing with the resin, filling in polymorph 2-part blocks, to check what can be achieved. Not many expectation but those 28 mm models that I want to create will be for home use only. Later I will check rubber etc.

Sooo, my local market can provide me the rather cheap PROCHIMA SINTAFOAM resin

Sorry for couldnt find another (shorter ) link, but this is exactly the place I am going to buy it.
Maybe someone has tried it or has any opinion about it. I don't want something tha gonna make extremely precise details and stuff, but something cheeeeeeap and useful.
Cheers!!

Hard to tell without a datasheet, but it looks like a fairly standard polyurethane resin. At that price, I would try it out.

Note that the description does say "for professional use", which may indicate that vacuum and/or pressure equipment is strictly necessary. Are you able to get a datasheet for it?

I found this page (it's official)


There is a pdf:


And some helpful vids. They dont use pressure equipment there. I hope it won't be necessary XD

It's not a very useful datasheet! It doesn't list any cured properties! The one useful bit of info is the 60 second pot life: that is extremely short and I recommend against it. It's likely to begin hardening while you're still pouring into the moulds!

Finally I bought the product and it was good especially for its price. Needs some attention with the bubbles (as almost every resin) but it's ok!
