We probably sell more of this resin than any of the other resins we offer just because it's so easy to use. Mix ratio is 1:1 by volume, and demold time is about seven minutes. Very low viscosity materials, so they'll pick up all of the detail in your mold. Off White cures to an ivory color. InstaCast will readily accept glass microballoons as a filler if you want to lighten your castings and save a few bucks in the process. InstaCast Off White is available in 2 pint (2.16 lb.) sets, 2 quart (4.31 lb.) sets, 2 gallon (17.2 lb.) sets and 10 gallon (86 lb.) sets.
