Re: Casting adhesive for patterns to mold box
A gentle reminder. Most RTVs are tin based and not sensitive to the sulfur found in ordinary modeling clay.toggle quoted messageShow quoted text
Some RTVs are platinum based and are quite sensitive to ordinary modeling clay, enough to give you a damaged mold.
There are safe clays often named 'clean clay' that is only a bit more expensive and safe for all your possible RTV molding.
It is worthwhile getting a bunch of it and using it only for your molding projects.
I know every Alumilte casting kit has it and it's sold by them and Smooth-on casting.
