I'm planning to make a silicone vacuumbag for infusion.
I see you are selling
Fumed Colloidal Silica to make a more thixotrope RESIN.
Is it possible to add it to Silicone too?
I want to make a silicone vacuumbag but I'm scared that if I brush the silicone onto the mould it will all drip off the sides and
all fall down to the deepest point of the mould.
Would this help to keep it better sticking to the sides of the mould or do you advice an other additive to the silicone?
