With a 100:10 mix ratio, 40-60 minutes working time, and 12-24 hours demold time, it offers exceptional elasticity (520% elongation) and tear resistance (23 kN/m). Its color-coded components ensure easy mixing without vacuum processing, making it perfect for both artistic and industrial applications. ## Description Product description Polycraft GP-3481F Silicone is a Condensation Cure Mould Making Rubber High strength silicone mould making rubber. Our silicone has been formulated for easy mixing by hand, with colour coded components (red or green) giving a visual aid to ensure mixing is adequate. The two components mix easily and because of the low viscosity most grades can be used without processing in a vacuum chamber. This silicone is suited for the detailed reproduction of figures, art objects and similar items. Outstanding release properties Long working time Medium Hardness High tear resistance High elasticity for easy removal of complex replica parts Can be made thixotropic (non flowable) for vertical surface replication Red silicone catalyst is by far the most popular catalyst to use with the GP-3481-F silicone, it gives great air release with longer working and demould times.

Very flexible, so it is easy to de-mould. Hope this helps, Tony. **Q: How much heat can this product withstand when set?** A: This silicone shouldn't really be used for higher temperature applications. it will take up to 100°c without much issue however going over 150°c will cause the silicone to soften and degraded quite quickly. **Q: I have an ornate plaster wall plaque that I'd like to make a mold of, so I can reproduce it in concrete for outside. Would this product be suitable?** A: Depending on many replicas you want to make it may be worth considering a PU rubber such as the 74-45 which would be more resistant to the concrete than the GP-3481 ## Frequently Bought Together - Polycraft GP-3481-F RTV Silicone Mould Making Rubber Kit, Mold Making Rubber, Includes Base and Catalyst, Precise Molding, Ideal for Crafts, and Industrial Use - 1.1 kg Kit - Polycraft SG2000 Paintable Fast Cast Polyurethane Liquid Plastic Casting Resin, Quick-Setting, Paintable for Crafting, Modeling, Prototyping, Easy-to-use Resin for Creative Projects - 2kg Kit - Bond It Silicone Release Spray - 500ml --- ## 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.gr/products/47914735-polycraft-gp-3481-f-rtv-silicone-mould-making-rubber-kit](https://www.desertcart.gr/products/47914735-polycraft-gp-3481-f-rtv-silicone-mould-making-rubber-kit) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-24*
