RTV-2 Moldmaking Platinum Cured Liquid Silicone Rubber: Uncompromising Purity for Superior Mold Making
Elevate your casting projects to a new level of clarity, durability, and precision with our RTV-2 Moldmaking Platinum Cured Liquid Silicone Rubber. This advanced two-part, Room-Temperature-Vulcanizing (RTV) system utilizes a premium platinum catalyst, setting a superior benchmark for applications demanding absolute material purity, exceptional optical clarity, and zero inhibition when casting polyurethane resins. Designed for the discerning professional, it delivers flawless performance in creating production-grade molds for resin art, specialty food applications, and high-value prototypes.
The choice of a platinum catalyst over conventional tin systems is a decisive factor for quality. This sophisticated chemistry eliminates concerns about odor, by-product migration, and mold degradation, ensuring your castings remain pristine and your molds last longer. This results in a cured rubber that is inherently more stable, exhibiting superior resistance to yellowing and thermal aging compared to condensation-cure systems. The exceptional transparency of the cured rubber facilitates easy bubble detection and provides a brilliant, optically clear view of your master model, streamlining the de-molding process for the most intricate pieces.
This formulation is meticulously engineered to balance exceptional physical properties with user-friendly application. Its low initial viscosity ensures it effortlessly penetrates the most minute details of a model, from subtle textures to deep undercuts, capturing every nuance with breathtaking accuracy. Once cured, it develops an optimal combination of a soft Shore A hardness for easy de-molding and a remarkably high tear strength. This crucial property allows you to produce dozens, even hundreds, of castings from a single mold without signs of wear or failure, making it an exceptionally cost-effective solution for series production.
Zero Inhibition with PU Resins: A primary advantage of this platinum silicone is its excellent compatibility with a wide range of polyurethane resins, minimizing the risk of cure inhibition that can plague other silicone types, especially with fast-setting resins.
Exceptional Recovery and Memory: The elastomer boasts outstanding elastic recovery, allowing it to be stretched and flexed significantly during de-molding and then return perfectly to its original shape, ensuring consistent casting dimensions over the entire mold lifecycle.
Ideal for Direct Food Contact Applications: With its pure, non-toxic formulation, this silicone is an excellent candidate for creating molds used in chocolate, candy, and ice cube production, complying with key food safety standards.
