RTV-2 Moldmaking Tin Cured Silicone Rubber: Precision and Durability for Creative Reproduction
Unlock the full potential of your mold-making projects with our professional-grade RTV-2 Moldmaking Tin Cured Liquid Silicone Rubber. This two-component, room-temperature-vulcanizing (RTV) system is engineered for artisans, prop makers, crafters, and industrial manufacturers who demand exceptional detail capture, operational ease, and long-lasting mold life. Whether you're casting resins, plasters, concrete, or low-melt metals, this silicone rubber provides the reliable performance necessary for creating flawless reproductions time after time.
Our formulation is designed to balance superior physical properties with a straightforward workflow. Its very low initial viscosity ensures it effortlessly flows into and around the most intricate patterns, capturing every fine line, texture, and undercut without trapping air bubbles. The convenient 1:1 mixing ratio by weight eliminates complex calculations, simplifying the process and ensuring consistent results every time. With a manageable pot life, you have ample time to mix and pour, while the room-temperature cure eliminates the need for specialized heating equipment.
Exceptional Tear Strength & Durability: Unlike standard molding rubbers, our formula is reinforced for high tear resistance. This crucial property allows you to de-mold complex and deep-under-cut castings with confidence, significantly extending the functional life of your molds and maximizing your return on investment.
Low Viscosity for Bubble-Free Casting: The thin, liquid consistency of Part A and Part B facilitates easy mixing and pouring. It self-levels perfectly and penetrates the finest details, minimizing the entrapment of air and reducing the need for extensive degassing in a vacuum chamber for many applications.
Optimal Shore Hardness for Flexibility & Stability: Once cured, the rubber achieves a balanced Shore A 25 hardness. This provides sufficient rigidity to hold the mold's shape during casting, yet offers excellent flexibility for easy release of the finished piece without damage.
Tin-Catalyzed Reliability & Compatibility: As a tin-cured (condensation cure) silicone, it offers wide compatibility with a vast range of model-making materials and casting resins. It is the ideal choice for producing polyurethane, epoxy, and polyester resin castings, as well as plaster and concrete elements.
