I was experiencing compatibility issues with Mold Star-15 Platinum Cure silicone rubber and 3D-printed objects. Totally frustrated with the predicament with the rubber not curing, I consulted the tech-rep with Reynolds Advanced Materials in Orlando. FL. and he suggested the Mold Max 29-NV, which is a Tin Cure product. With the prescribed instructions, I had a very successful ending.
If you are molding 3D objects, I strongly suggest the Mold Max 29-NV.
