Important: This Product Intended for Industrial & Professional Use Only

  • DO NOT use for food molds.
  • Thick, High viscosity Liquid Silicone (Consistency similar to latex rubber)
  • Mix two parts thoroughly, if not mix well, silicone rubber will become sticky, and will not cure properly.
  • DO not mix over 2% Catalyst, using Catalist over 2% will cure silicone quickly, working time get too short.
