Hello!
I am trying to cure a large amount of PDMS in a platinum silicon mold. How long should I cure it for? It is a cone shape and has a thick base of about 8 mm and the end (top) portion is really thin: about 1 mm or a little less. I degassed it for about 3 hrs. I know the suggested is 30 mins but it wasnt ready until much later.
my plan was let it sit for 24 hrs at room temp then put In drying over at 60 degrees for a couple hours.
thoughts?

So-called platinum-cured silicones are normally cured with a Pt-complex catalyst and the time for cure depends on the particular catalyst ranging from minutes to 24 hours at 50°. Usually solid Pt is not employed. An intro to the technology is found in the lit attached "Reactive Silicones" in the section es entitled vinyl silicones and hydride silicones. If you don't want to go deeply into the topic simply check the manufacturer's tech data sheet.
