Mixing ratio: 2 parts resin to 1 part hardener 2:1.
Set time: set time is determined by the size of the casting. Thin films take longer; sometimes as long as 48 hours. Large castings generate more heat and therefore set faster; possibly six hours or less. Exact set time for a particular casting can only be determined by experimentation.
