Operation Instruction for  Silicone  for mold:

During operate the three impotant thing to pay attention :
  1. weigh theliquid silicone rubber and curing agent exatly .
  2. Stir theliquid silcone rubber and curing agent evenly .
  3.we shouldchoose the right hardness to making diffirent size of product mold.

(Note: our company does not recommend you to add silicone oil. If a special soft silicon mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demould.)
