Separately weigh out the correct amounts of the base component and the reaction component. Then, use a disposable cup to manually mix these two components quickly and thoroughly.
Next, immediately pour the finished mixture into a mold onto which a separator agent has been carefully applied. The mold must then be immediately closed and fastened shut with a screw clamp or with fastening straps.
After 45 to 60 minutes, the mold can be opened and the foam appliances can be removed from the mold after thorough powdering.
Cold Foam SF appliances are bonded in place with Spirit Gum or Pros-Aide.
