Metallic Powder in Urethane Rubber

[RockitScience]

Hi RPF!

Has anyone had any experience adding metallic cold-casting powders to urethane rubber? Smooth-On claims it can be done in conjunction with so-strong tints in their UreCoat product, but I'd like to know if anyone's actually tried and had success with that or any other brand. Thanks!

That’s crazy.. TJack did you coat the surface of the mold with the metallic powder first like you would do when cold casting resin, or did you just mix the powder into the rubber?

Yep, dusted the mold with the powder and then did a couple layers of black tinted rubber. Then I back filled that with the foam

That's fantastic. Any tips or tricks? Or was it pretty simple?

pretty straightforward - just make sure to get even coverage with the powder
