Smooth-Cast 65D has a unique gradual cure profile that makes it ideal for rotational casting applications. Fully cured castings are semi-rigid and exhibit good impact resistance. 65D can also be cast solid for a variety of industrial and art-related applications.
I had a lot of fun, it worked in my applications and is very simple to use and you don't really need to be exact on the measurements. My applications were small so it went a long way, I'm still playing with it, my son especially appreciates the fast results. I don't know if there are pigments available to mix in, I used ink and dye and paint with mixed results!
