Hi I want to make pressure drive pulley out of silicone, but all i can find is 40A stiffness on the net, do you happen to have >60A silicone mold, preferably 70A or higher?
The Answer is no, tin cure silicones are not skin safe. Meaning they cannot be used for life casting. Even platinum cure silicone needs to be officially certified as skin safe. If you are life casting, you need to look for skin safe Platinum cure silicones that can be applied to the skin with a paint brush.
I accidentally added significantly less hardener than I should have to my tin cure silicone. I just found this out after having the mold in the pressure pot for hours already. Should I be patient or is the mold lost. I added about 2% (my usual B compound) when it should have been 5% (accidentally used wacker t21)
Awesome info. Thank you so much.
Please may I ask - can I add liquid dye into the tin silicone?

I would like to ask, are the tin cure silicones "skin safe" after you wash them? Like can I touch it or are they toxic?
Bump. Anyone know this?

Which one is best for epoxy resin?
Gracias, muy bien explicado
