SternTek® Duplicating Material

1. If I do not have the SternTek® Duplicating Dispensing Unit, how can I measure the duplicating material?
You may dispense equal amounts of base and catalyst in measuring cups or in side-by-side cups and "eyeball" an equal ratio.

2. About how many molds will the 2 bottles (1kg of each) of the duplicating material make?
Of course, it depends on the size of the models and how thick you make them. As a rough estimate, 8-10 models can be made from the two 1kg bottles. Adding pieces of old duplicating material can reduce the amount of "fresh" material needed to make the mold.
