Siraya Tech Defiant 15 Platinum Silicone Mold Making Kit, Food Safe, Shore A 15 Hardness, Ideal for 3D UV Resin Projects, Easy Curing, No Coating Required, Durable, Versatile, 2.2 lb Set Clear

It actually works! I've wanted to make silicone molds of resin prints for years but the dreaded cure inhibition has foiled every attempt. Follow instructions on sirayatech web site and it should work. Tried several resins and only when I skipped the UV cure under water was there a small amount of inhibition. Love this stuff wish it was more economical. I've tried both hardness's.

I'm confused, this is at least as hard as my 25 silicone from this same brand

Buena calidad. Ya he utilizado esta marca con otros productos. Estoy satisfecho con los resultados obtenidos. Recomiendo Siraya Tech.

Works good

I really wanted this to be a "how-to use it review" but instead I'm going to tell you "how to save your time" by not buying this regular albeit overpriced silicone expecting it to be more compatible with resin prints.In the instructions they tell you to use their resin cure it underwater, which works fine for solid parts. but when you have cavities, even with multiple washes, curing stages, scribbing, doesn't matter, still won't cure.In my case there is a 2mm gap that's 20mm long and 30mm deep, that is facing upward, it won't cure.I increased the size of the cavity to 4mm gap, still won't cure.I've remade this mold 4 times now, reprinted the master 3 times, tried minimal to maximum cleaning, curing starting at the rated 30min scaling up to hours, with the same results. wasted time, dashed expectations.
