## Description

Are you frustrated with curing inhibition issues affecting your silicone projects when working with resin prints?Introducing the all-new Defiant 15 from Siraya Tech – offering exceptional resistance to platinum poisoning without the need for complex post-processing. By curing your part submerged in water for just 30 minutes, Defiant 15 ensures a perfect cure without the hassle of clear coating.Product Note:Developed in collaboration with experienced prop-making professionals, Defiant was designed to simplify post-processing and maximize the success rate of silicone curing. Through rigorous testing with over 30kg of silicones, we've found the ideal combination. We dedicate Defiant silicone to the prop-makers in our community who have contributed to our growth.Platinum silicone poisoning can be challenging to overcome, as it is caused not only by 3D printing resin but also by the silicone manufacturing process. To achieve the best results, it's crucial to identify the perfect blend of silicone and resins. Defiant 15 has been engineered to exhibit greater tolerance than traditional platinum silicones, but some resins inherently offer better compatibility with silicone and require less post-processing. Features: Hardness index of Shore 15A.Exceptional resistance to silicone poisoning, especially from UV resin.Minimal post-processing is required for proper mold curing. Ideal balance of hardness and flexibility for general molding applications. Outstanding material strength, including tear and heat resistance.Resin Selection and Post-Processing: Essential for 3D UV Resin Prints

Review: It actually works! - Casting from 3D printed resin masters is usually a nightmare, as you either have to use tin-cure (awkward to weigh out) or clearcoat the parts and pray the silicone isn't cure inhibited. Not anymore! I've tested this with various 3D printed resin parts and it works perfectly every time- save for one slight mistake where I didn't mix the parts properly (as a side note, I find adding a pigment to one part before mixing can ensure proper combination). It's also an extremely well behaved silicone in general, strong and not too thick, and cures fast enough to get a mould made quickly but not so fast that you rush pours- as silicone rubber goes it's pretty simple to use. Otherwise general mould making wisdom applies; have a vacuum chamber to avoid bubbles, ensure both halves are properly mixed, etc etc. Honestly even if this was just "normal" silicone I'd recommend it, but the fact it works with photopolymer resin is a massive bonus. Highly recommended for anyone interested in casting rubber.
Review: Great for mould making, especially dice! - I picked up the Siraya Tech Defiant 25 Platinum Silicone kit to make dice molds for my resin projects, and honestly, I was impressed from start to finish. I’ve tried a few different silicones over the years, but this one stood out for a couple of reasons. Easy Mold Making, Even for First-Timers Mixing the silicone parts was genuinely straightforward—just combine, mix thoroughly, and pour. I wasn’t worried about missing the pot life or it getting too thick way too fast. What really sold me was how smoothly it flowed around my dice masters and settled into all the small details. If you’re worried about bubbles or fine print not coming out, don’t be; the results were crisp. No Curing Headaches One of the frustrations with making molds using 3D printed pieces is the risk of curing inhibition, but this silicone just worked. I didn’t need to coat my models or do anything special; it cured perfectly next to my UV resin prints—no sticky spots or half-cured messes. Awesome for Dice The 25A hardness is just right—it holds its shape but doesn’t feel like a brick when you’re demolding. My finished dice popped out cleanly, and the molds have lasted through a few sets without stretching or tearing. The translucency of the cured silicone also made it easy to check for air bubbles before the mix set up, which saved me from having to remake molds. Works Seamlessly With Siraya Tech Fast Navy Grey Resin A huge bonus for me has been using these molds with the Siraya Tech 2kg Fast Navy Grey resin. The silicone and resin work together perfectly—no curing issues, and the detail from the mold comes through clearly in the final casts. The Fast Navy Grey resin cures reliably in these molds without sticking or leaving any residues, so every dice pour came out crisp and clean. Great Value & Size The amount in the kit is generous, and I got several dice molds out of one batch with some left over. For anyone making custom dice, the kit’s size and ease of use make it a practical, reliable choice. Would I Recommend It? Absolutely. If you want an easy mold-making experience—especially for detailed work like dice or resin crafts with popular resins like the Siraya Tech Fast Navy Grey—I’d say give the Siraya Tech Defiant 25 a shot. It took the stress out of the process and gave me professional-looking results with less prep and cleanup.
