Pure Sil 20 Silicone Rubber provides a flexible, two-part mold-making solution that uses a tin-catalyzed, condensation-curing formula. As it cures, it delivers excellent tear resistance and minimal shrinkage, making it ideal for capturing intricate textures and fine details.
Because it has a Shore A hardness of 20, Pure Sil 20 offers a softer alternative to Pure Sil 30. Consequently, it allows users to demould delicate features with greater ease. In turn, this makes it especially useful for molds with complex surfaces or fine lines. Moreover, artists and makers rely on its precision to replicate textures with clarity and depth.
To get started, mix Part A and Part B at a 100:3 ratio by weight. Next, stir thoroughly and apply in layers to achieve optimal results. For best performance, ensure consistent mixing and even application throughout the process.
Recommended Applications:
- First and foremost, create molds for resin, gypsum, and candle wax
- In addition, prototype and replicate textures for design and engineering
- Furthermore, build educational kits for material science demonstrations
Additionally, Pure Sil 20 works seamlessly with polyester, epoxy, and urethane resins. Not only that, but you can also cast low-melt alloys and gypsum-based polymers with confidence.
Although it’s not food-safe, it remains an economical and reliable choice for mold-making in art, craft, and industrial settings. For brush-on techniques, add RTV Thixo thickener. To accelerate curing, use Pure Sil Accelerator.
Ultimately, Pure Sil 20 empowers artists, educators, and makers with flexibility, precision, and dependable performance. Whether you’re crafting prototypes, teaching material science, or creating detailed molds, this silicone rubber helps bring your creative visions to life with ease.
