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.

Worked exactly as expected from the instructions. ## Frequently Bought Together - Polycraft GP-3481F RTV Silicone Mould Making Rubber 1.1kg Kit (Clear Catalyst) - BBDINO Super Elastic Silicone Mould Making Kit, 21.16 oz Liquid Rubber for Casting 3D Moulds | Food Molds 1:1 by Volume, Jade Green - Adjustable Mould Housing Kit for Silicone Rubber - Plastic Frame for DIY Resin, Candle, and Soap Moulds - Free Combination Design --- ## 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.hr/products/48030545-gp-3481f-rtv-silicone-mould-making-rubber-1-1kg-kit](https://www.desertcart.hr/products/48030545-gp-3481f-rtv-silicone-mould-making-rubber-1-1kg-kit) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-21*
