How To Vent a Silicone Mold to Eliminate Bubbles In Casting
Step 2: Dispensing, Mixing, Vacuuming and Pouring Mold Max XLS
Weigh 100 Parts of Mold Max® XLS Part A and 4 Parts of Mold Max® XLS Part B. Combine Parts A and B in the mixing container and mix with a drill first, then by hand. To ensure proper mixing, pour the rubber into a second, clean mixing container and mix again. Then, vacuum the mixture at 29 inches of mercury. Pour the XLS® into the lowest corner of the mold box and allow it to rise over the model. Allow the XLS® rubber to cure for 16 hours, then test the mold to make sure that it has fully cured.
