Thermoset Mold Rubbers
These mold making rubbers require heating until they are melted. After which they are poured over the model. They harden after cooling. Most of these products may be reused. The advantage is that there is no weighing or mixing. The draw back is that the materials are heated in excess of 130-degrees F which can cause burns or melt a delicate model. Use Bubble Buster to reduce surface bubbles when using Composi-Mold for creating molds.
