How To Make a Silicone Mold of a Fish


This moldmaking video shows the process of molding an actual trout for taxidermy or propmaking purposes.  The materials used are Ecoflex® 00-35 silicone and Smooth-Cast® 61D tinted with So-Strong pigments.  Ecoflex® 00-35 is a very fast setting silicone rubber which is not affected by the low temperature of the fish specimen.  Smooth-Cast® 61D is a mercury-free impact resistant urethane casting resin.
