Our comprehensive range of tin-catalyzed RTV (Room-Temperature Vulcanizing) silicones offers exceptional versatility for general-purpose mold making, prototype development, and industrial sealing applications. These two-component systems demonstrate excellent adhesion to various substrates and provide reliable performance with adjustable hardness from soft Shore A 10 to semi-rigid Shore 60. With convenient 1:1 mixing ratios and customizable viscosities, our condensation cure formulations deliver optimal results for architectural concrete molding, art reproduction, and general industrial encapsulation where extreme thermal stability isn't critical.
Tin Cure Silicone Rubber is a two-component RTV-2 condensation cure liquid silicone rubber for flexible mold making. It supports economical production and reliable reproduction of detailed patterns. After mixing with the appropriate catalyst, the material cures at room temperature. It forms a flexible silicone mold for casting gypsum, plaster, concrete, epoxy resin, wax, artificial stone, craft products, and general industrial materials.
GT Silicon / Dongguan Gangtian Polymer Materials Co., Ltd. is a China-based manufacturer and supplier. We provide standard and customized tin cured silicone grades for mold makers, distributors, OEM buyers, and industrial users worldwide.
Tin Cure Silicone Rubber is also known as condensation silicone rubber or RTV-2 tin cure silicone rubber. It is widely used when buyers need a practical, cost-effective silicone material for mold production. The liquid silicone system flows around the master pattern, captures surface details, and cures into an elastic rubber mold at room temperature.
This category is especially suitable for gypsum and plaster crafts, concrete and cement products, epoxy resin decorations, wax and candle molds, artificial stone, sculpture reproduction, prototype molds, and general industrial mold making. GT Silicon supports standard product supply and customized formulations for mold making projects. We help buyers select grades based on mold size, casting material, processing method, demolding needs, and expected production use.
If you are comparing RTV-2 mold making silicone for a new project, you can request a sample for testing. You can also send your application details for our technical recommendation before placing a volume order.
GT Silicon supplies tin cured silicone rubber grades for different molding processes. Options range from soft, flexible materials for detailed craft molds to stronger grades for larger molds and repeated casting. Mold making requirements vary by project. The right hardness, viscosity, working time, curing time, and catalyst ratio should match the pattern structure, casting material, production speed, and demolding method.
The table below gives a practical category-level guide for choosing liquid silicone rubber for molds. Exact parameters can be adjusted or confirmed according to the selected grade and order requirements.
Soft Tin Cure Silicone Rubber is recommended for molds with fine textures, undercuts, delicate edges, or complex geometry. Its flexibility helps the mold release castings without damaging small details. It is useful for plaster crafts, resin ornaments, candle molds, small statues, decorative products, and prototype duplication.
For artistic, craft, or small-batch molds, a softer tin cure silicone can balance detail reproduction and handling comfort. Our team can review the pattern size, surface detail, casting material, and demolding process. We then recommend a suitable formulation for your production needs.
For large molds, concrete products, artificial stone, cement components, or repeated casting, buyers often need stronger tin cured silicone rubber. These grades are selected for better resistance to tearing and deformation. They also provide more mold support, better dimensional stability, and improved service life under practical casting conditions.
High tear strength tin cured silicone is useful for architectural decoration molds, larger sculptures, concrete panels, industrial replicas, and similar applications. It is suitable when the mold must withstand heavier casting materials or frequent demolding. Final selection should consider mold wall thickness, expected casting cycles, release method, and the use of pouring, brushing, or a support shell.
GT Silicon Tin Cure Silicone Rubber is developed for practical RTV-2 mold making needs. Buyers choose it for reliable curing, easy processing, flexible demolding, and cost-effective performance. Compared with some platinum cure systems, tin cure silicone is often selected for general industrial and craft mold applications. It is a practical option when food-contact or special high-purity requirements are not the main priority.
As a company serving customers worldwide since 2003, GT Silicon combines silicone material manufacturing with R&D improvement, OEM/ODM support, and export-oriented service. Our goal is to help buyers obtain a suitable formulation. We do not force every mold project into one standard product.

Tin Cure Silicone Rubber is mainly used for RTV-2 mold making in craft, decorative, construction, prototype, and general industrial applications. It forms flexible molds that reproduce detail and release castings made from many non-food casting materials.
The following guide summarizes common uses and buyer considerations. For food contact, skin contact, or special regulatory requirements, buyers should confirm the appropriate certified grade. A suitable platinum cure silicone option may be recommended depending on the final use.
Choosing the right Tin Cure Silicone Rubber is not only a matter of hardness. Buyers should also consider viscosity, working time, curing time, mold size, pattern complexity, casting material, and expected casting quantity. A small decorative resin mold may need excellent flexibility and fine detail capture. A large concrete mold may require more support and stronger tear resistance.
GT Silicon can recommend an RTV-2 silicone formulation after reviewing your actual application. To speed up selection, please share your target Shore A hardness if known. Also tell us whether you pour or brush the silicone, the master pattern size and shape, and the casting material.
Tin cure silicone rubber and platinum cure silicone rubber are both important RTV-2 mold making materials. They are selected for different application needs. Tin cure silicone, also called condensation cure silicone, is commonly used for economical industrial and craft mold making. Platinum cure silicone, also called addition cure silicone, may suit applications that need higher purity, specific food-grade suitability, or special performance. The correct choice depends on the formulation and certification.
If your project involves general molds for plaster, gypsum, concrete, resin, wax, or artificial stone, tin cure silicone rubber is often a practical starting point. If the mold is intended for food-contact, life casting, or a special regulated application, GT Silicon can help review the requirements. We can then recommend a certified platinum silicone or another suitable silicone material where appropriate.
As a custom Tin Cure Silicone Rubber manufacturer and supplier, GT Silicon supports B2B buyers who need more than a standard catalog item. Mold makers, distributors, private-label brands, and OEM customers can request adjustments to silicone parameters, color, catalyst support, label, logo, and packaging. These options can be matched to project and market requirements.
