How To Mold a Captain America Cosplay Helmet Using Rebound™ 25
Step 1: Preparing, Dispensing and Applying Rebound 40
This finished Captain America replica helmet sculpt was made using non-sulfur clay and is ready to be molded.
A brush-on mold will be made using Rebound™ 40 platinum-cure silicone rubber. The rigid support shell will be made from Free Form Air epoxy putty. Rebound™ 40 has a mix ratio of 1A:1B by volume or weight. Dispense Parts A and B and mix thoroughly until there are no color streaks. Apply a thin coat of rubber to the original model. Use a stippling motion to force liquid rubber into the areas of detail. Allow the first layer of mold rubber to partially cure. In order for subsequent layers to bond to the previous layers, they must be added while the previous layer is partially cured, not fully cured (tacky but not in a liquid state).
