When making a mold out of two part rubber to use to cast a resin part, I use a styrene made mold box into which I attach the master to the floor of the box. After mixing the two part rubber I pour it in over the master. I have always used rubber cement to attach a master to the floor of the mold box. When making a mold this past week I had a master which was the side of a reefer rise into the rubber on one end of the mold. The rubber cement did not hold this time. So began thinking there may be a better product to use to attach the master part rather then rubber cement. I am asking those of you who make molds what adhesive you use, if any, to attach a master to the mold box form if used.
