Howdy,
I have a personal project I'm working on that will be cast in slush latex.
It's been years since I've made anything from latex. I remember some stuff I learned from my short stint working in SPFX make-up, but it's been too long and my memory is rusty :$
Anyhow, is the standard mold material of choice still Hydrocal :confused
I stock plenty of Ultracal in my shop for making waste molds for resin casting and fiberglass work. I like it because it's much stronger and denser then Hydrocal.
My question is this...
(1) Will a Ultracal mold for molding latex be slower drying than a Hydrocal mold because it's more dense/less porious so it will take longer for the moisture to be drawn-out for the latex to form a thick skin?
(2) How long will the surface details of Hydrocal molds hold-up???
(3) And lastly, is there a need for mold release or some techniques for easy de-molding of parts???
Thanks in advance... Nick :cool
