Nicknamed Brown , Kneadatite Brown/Aluminum is an epoxy putty well known for its long work life, non-grainy texture and its ability to hold fine detail. Brown/Aluminum cures hard so it may be filed, sanded and cut to achieve hard edges, sculpt machines and build understructure. It may also be mixed with Blue/Yellow to increase the hardness of Blue/Yellow . Miniatures sculpted with Kneadatite withstand the heat and pressure of the mold making process (vulcanization). Mixing proportions can be adjusted to control curing time. 4" Length
