We probably sell more of these resins than any of the other resins we offer just because they're so easy to use. Mix ratio is one to one 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, White to a bright white. Insta-Cast will readily accept glass microballoons as a filler if you want to lighten your castings and save a few bucks in the process. Use the Off White if adding dark colors, White for pastels or if you want a nice white substrate to paint onto. The White is slightly lower viscosity than the Off White.
Instacast White is available in a 2 gallon (16.9 lb net weight) set.
