Hello,
We are making wearable pieces currently from Simpact 60A by Smooth-On. Simpact has been delightfully durable, but Urecoat is giving us a hard time. Much searching around the forums has lead me nowhere yet, as many recommendations aren't giving the exact results we want. What we are aiming for is wearable costume pieces that are UV and tear resistant with a high gloss look to them.
The process we are doing is currently;
Slush/rotary casting Simpact 60A to get the hollow part (highly successful)
Gluing Separately cast parts together (also successful)
Coating the entire project with Urecoat (where the issue is now)
The result we are getting is a highly durable wearable piece with a high gloss finish, but it has the effect of water on a waterproof surface. It kind of "blobs." Our model is sanded to almost perfect smoothness and well primed before casting, so the parts we are coating with urecoat are not the source of the uneven gloss effect.
Smooth-On recommended to me, in a reply to technical support, to thin out the Urecoat with mineral spirits to apply it onto the surface as thinly as possible. My fear is that it is not the thickness of the material we are applying, but the Urecoat's capacity to stick to the Simpact, like waterproofness.
So what we are wondering now is if maybe using Urecoat is a bad idea, what could be used in it's place if that is the case, or if perhaps we are improperly handling the Urecoat.
Thank you for your time!
