The alumilite quickset silicone is not a brush on silicone. It is meant for pouring and therefore does not need the thi-vex thickener. If you make it thicker, it will be difficult for it to copy very intricate features.I hope this helps. **Q: Will this work with Mold Maker by Alumilite?** A: We don't test Thi-Vex with non-Smooth-On silicones. **Q: Part A of my smooth-on got hard, can i use this with only part B to make a mold?** A: No, that won't work **Q: Can I use this with OoMoo30?** A: It will work for OoMoo30, but I had much better results using rebound 25 with the thivex ## Frequently Bought Together - THI-VEX - Thixotropic Agent for Thickening Smooth-On Silicone Rubbers - 1 Ounce Bottle - Rebound 25 - Brushable Platinum Silicone Rubber - Gallon Unit - Ease Release 200 Mold Release - 14 Fluid Ounce Aerosol Can --- ## 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.com.br/products/22727565-smooth-on-thi-vex-thixotropic-agent-for-thickening-silicone-1](https://www.desertcart.com.br/products/22727565-smooth-on-thi-vex-thixotropic-agent-for-thickening-silicone-1) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-10-13*
