How to Make a Silicone Brush On Mold of a 3D Object
Step 5: Casting and Demolding
Measure equal amounts of A & B Smooth Cast® 300. Mix thoroughly, make sure to scrape the sides and bottom of container several times.
Slowly pour the liquid mixture into the mold. Rotate the mold during the pour to eliminate air bubble entrapment. Allow the resin to cure for 20 minutes. CAUTION: Smooth Cast® 300 becomes VERY HOT! Let cool before handling.
Remove the mold from the bucket. Remove the Plaste-Paste® shell. Carefully remove the casting from the rubber mold. The finished casting is an exact duplicate of the original.
