Back in the late 40's and early 50's there was Celastic, plastic impregnated fabric that you dipped in acetone, and then laid up in strips to form an object, then in the late 50's to the present, there was fiberglass. I just realized that fiberglass has been around nearly half a century and it's still considered State of the Art! What's up with that?
I can't believe something new isn't out there yet that's quicker and easier to work with. I know there is "Plastisol" which is a hot pour vinyl you heat to 350 degrees, then slush into your mold, but I don't know if it will work in silicone. Normal urethanes seem to work, but it takes 8 - 10 shots to build up a good thickness. I've tried "Sylox" thickener in urethane, but it makes the resin brittle, and we can't have that!
I'm thinking there has to be something out there that's about as thick as say, cake batter when you pour it in, and about the consistency of polyproplyene (margarine bowls) or harder when cured.
Any thoughts form the hi-tech folks here? Thanks!
