There are a few ways to speed up the cure of TinSil® (tin-cured) or PlatSil® (platinum-cured) silicones. For PlatSil products, use PlatSil 71/73 Part X Accelerator. For TinSil products, use TinSil FastCat Accelerator or mix in more of the part A - however, note that you will run out of Part A faster than you will of Part B. Only PlatSil silicone curing can be accelerated with heat, as Tin is a humidity-cured material and heat will not have an effect.
