Key Features and Benefits
High Tear Strength: This RTV-2 silicone rubber has a high tear strength, making it resistant to tearing and ripping. This is crucial for creating molds that can withstand the stress of repeated use.
Excellent Detail Reproduction: The low viscosity of the silicone rubber allows it to flow easily into the finest details of the original model, ensuring that even the smallest features are accurately reproduced.
Dimensional Stability: The material has minimal shrinkage, ensuring that the molds maintain their original dimensions and integrity over time.
Ease of Use: The silicone rubber is easy to mix and pour, making it suitable for both beginners and experienced users. It cures at room temperature, reducing the need for specialized equipment.
Versatility: In addition to phone case molds, this silicone rubber can also be used for a variety of other applications, including making molds for small objects, figurines, and other detailed items.

Applications
Phone Case Mold Making: Ideal for creating molds for phone cases, ensuring high precision and durability.
Small Object Molds: Suitable for making molds for small objects and figurines, where detail and accuracy are crucial.
Prototyping: Excellent for creating molds for prototypes in various industries, including automotive, aerospace, and consumer goods.
Processing and Handling
Surface Preparation: Ensure the surface of the original model is clean and free of grease, oil, and other contaminants. A light "blow over" with compressed air is recommended to remove any dirt or particles.
Mixing: Weigh 100 parts of the base and 10 parts of the curing agent in a clean container. Mix until the curing agent is completely dispersed and a uniform color is obtained.
De-airing: Remove entrapped air by placing the mixture in a vacuum chamber. This ensures a bubble-free mold.
Pouring and Curing: Pour the mixed silicone rubber onto the original model as soon as possible. The material will cure to a flexible rubber within 4-6 hours at room temperature.
