## Description

Product Description

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.

## Features

- Extra Resistance to Curing Inhibition: Defiant 25 can resist sulfur poisoning due to UV resin much better than common platinum silicone. With only 30 minutes of curing the printed part immersed in water, Defiant 25 can cure without any problems. No coating required. Defiant clear silicone mold works best with our Fast, Build, Blu, Easy and Sculpt resins.
- STRONG AND DURABLE - Compared with others, Siraya Tech Defiant 25 clear silicone mold has better flexibility and higher tear resistance, and the silicone molds have a longer service life and can be reused many times. More roll per mould means lower cost per cast. This silicone rubber can withstand temperatures up to 200°C.
- Fine viscosity: Defiant 25 is easy to pour and degass compared to other 25A silicone. It is thinner and therefore makes the whole process easier even for beginners. You don't need an expensive professional vacuum chamber to remove bubbles and with good pouring technique, you can achieve bubble-free care.
- VERSATILE AND FOOD SAFE - Siraya Tech Defiant 25, a platinum food grade silicone, excels in both food and craft applications. Perfect for candy molds, chocolate, cake and ice molds, also fits resin molds, wax, candle and soap molds, casting, architectural details and figure making. Its balanced hardness and flexibility make it ideal for different molding tasks and DIY projects.
- Easy Mixing Ratio 1A: 1B - Defiant 25 silicone rubber is easy to mix, mixing ratio of 1:1, self-degassing and very easy to use. This liquid silicone mold can be easily used by beginners without any experience. Please feel free to contact us if there is any problem.
