THE USAGE OF SILICONE FOAMS: Silicone Foams can be used for a variety of industrial and special effects applications including making foam filled appliances, padding /seat cushioning, orthotics/orthopedics, potting and encapsulation of electrical circuits and vibration dampening. THE CHARACTERISTIC OF SILICONE FOAMS: 1.Mixed Viscocity 2.Very soft 3.Excellent temperature resistence IMPROVE SURFACE FINISH AND MINIMIZE VOIDS WITH BACK PRESSURE: Use a board that will completely cover the mold opening. Using a drill bit, drill 3 holes in the board spaced a few inches / cm apart. Make sure that, when the board is placed over the mold opening, the holes are over the mold cavity and rising foam will be able to make it through. Apply Ease Release 200 thoroughly too both sides of the board and into the drilled holes. Mix and pour foam into mold cavity and place board over mold opening. Hold board firmly in place. As foam rises in the mold cavity, some foam will grow out of the drilled holes. After the foam stops growing, you can let go of the board. Do not demold for at least 20 minutes.
