Review: A must-have for molds from 3D printed raws!!! - This has become my go-to silicone whenever I want to get a mold of a 3D printed item. In the past I got to wait at least a week after printing to let the epoxy de-gas, prime and paint the raw model ... that got old real fast. Siraya Tech Defiant came to the rescue and I now use it for just about anything for which I need silicone. Mixing is a breeze and the ratio is a simple 1:1 (doesn't matter, if I go by weight or volume ... I've never had it not set up). The viscosity of the silicone is low enough to mold to the tiniest detail. And all that without bubbles!!! A very nice "extra": This silicone withstands heat. I use leftovers and pour them into lids, the bottom of a cup, coasters, etc. and use those pieces to solder on and clean the tip of the iron on the go. Review: Great silicone. Works as advertised. - Let me start out by saying I rely on silicones and casting products to make a living. I have tried several 15-30 durometer silicones and had always had strange problems with them. Having said that, this silicone did not have any of the issues that other *more costly* silicones had that were comparable. The fact that I have also had zero cure inhibition issues when used in conjunction with elegoo ABS like 2.0 (that is my go to resin for my 3D printer) is just like the cherry on top of an already great silicone. It degasses extremely fast which speeds up production, while having ample work time when making smaller molds. I have used both the 15 and 25 duro varieties and have been equally impressed with both. One last thing worth noting is that when I had used other comparable platinum silicones that are a 1to1 ratio I seem to get a considerable amount of shrinkage. This has not been the case with the siraya tech silicone, even when using the molds repeatedly in a heated pressure pots I have not had any noticeable shrinking in any of my molds. Lastly, in my opinion it is very affordable, to be honest at its price point I didn’t expect to be this impressed by it. It is very seldom that I use a product that checks all the boxes, I wouldn’t change a thing except maybe making the product available in larger kit sizes and expanding the durometer range to include maybe a 45. It has quickly become my go to silicone for smaller molds that require some flexibility. These are my views and opinions and your mileage may vary. ## Features - Extra Resistance to curing inhibition - Defiant 25 can resist sulfur poisoning due to UV Resin much better than common platinum silicone. With just 30 minutes of curing the printed part submerged in water, Defiant 25 can cure without issues. No coating is needed. Defiant silicone clear 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 making has better flexibility and stronger tear resistance, and silicone molds have a longer life span and can be reused many times. More pulls per mold mean lower cost per cast. This silicone rubber can resist temperatures up to 200C. - Thin Viscosity - Defiant 25 is Easy to pour and degas compared to other 25A silicone. It is thinner and thus making the entire process simpler even for beginners. You do not need an expensive professional vacuum chamber to remove bubbles and with a good pouring technique, you can get a bubble-free cure. - Versatile & Food Safe - Defiant 25 from Siraya Tech, a food-safe platinum silicone, excels in both food and craft applications. Perfect for molds of candy, chocolate, cake, and ice, it also suits resin, wax, candle, and soap molds, casting, architectural detailing, and figure making. Its balanced hardness and flexibility make it ideal for diverse molding tasks and DIY projects. - Easy Mixing Ratio 1A:1B - Defiant 25 mold making silicone rubber is easy to mix, mixing ratio of 1:1, self-degassing, and very easy to use.

I made some chocolate molds with it, and I'm really pleased with the resulting chocolates. It molded around PLA (3-D printed models) very well. It kept so much detail that I was able to print the models on a holographic surface, which transferred to the mold, which transferred all the way to the chocolate and made excellent party favors. I used a vacuum pot and vacuumed the mixture 3x before pouring to get all the bubbles out. The working time is supposed to be 15 minutes, but it felt like it was starting to get gloopy around 13 minutes. I was working in a fairly warm environment at the time. ## Frequently Bought Together - Siraya Tech Defiant 25 Platinum Silicone Mold Making DIY Kit, Food Safe, 25A Hardness, Ideal for 3D Printer UV Resin, Easy to Stop Curing Inhibition, No Coating, for Casting Epoxy Resin (35.3 Oz) - Siraya Tech Fast ABS-Like 3D Printer Resin 405nm UV-Curing Non-Brittle High Precision 3D Printing Liquid Standard Photopolymer Resin for 8K Capable LCD DLP 3D Printing (Navy Grey, 1kg) - Siraya Tech Blu 3D Printer Tough Resin with High Toughness Resolution Strong and Precise 3D Printing 405nm UV-Curing Rapid Resin for LCD DLP 8K 3D Printer (1kg, Clear V2) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/495158149-defiant-25-silicone-mold-making-kit](https://www.desertcart.hk/products/495158149-defiant-25-silicone-mold-making-kit) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-04-24*
