SPREE Two Part Silicone Rubber 5KG Translucent
SPREE Two Part Silicone Rubber SPR-RTV-072 5KG is a high-performance RTV-2 silicone rubber designed for detailed mould making, casting, prototyping, and technical applications. This two-component system combines a silicone base with a curing agent to produce a flexible, durable, and tear-resistant elastomer at room temperature.
SPREE Two Part Silicone Rubber for Mould Making
The material offers excellent flowability, allowing it to reach intricate textures, undercuts, fine details, and complex geometries on a master model. Therefore, it works particularly well when accurate reproduction and dimensional stability are important.
Once cured, the silicone forms a flexible mould that can withstand repeated casting cycles. Its translucent appearance also provides improved visibility during pouring, degassing, curing, and mould preparation.
RTV-2 Silicone Rubber with Excellent Detail Reproduction
SPR-RTV-072 uses a condensation-cure system and provides a practical solution for professional mould production. Furthermore, its mechanical strength and flexibility help the finished mould maintain its shape during repeated demoulding.
The cured silicone offers high elongation and tear resistance. As a result, it can handle moulds with undercuts and complex shapes more effectively.
Applications of SPREE SPR-RTV-072
This two part silicone rubber is suitable for a wide range of professional and creative applications.
Arts and Crafts Moulds
Use it for moulds used with:
- Sculpture

How to Use SPREE Two Part Silicone Rubber
First, prepare the master model and ensure the surface is clean, dry, and free from contaminants. Next, measure the required quantities of Part A and Part B according to the recommended 100:3 mixing ratio by weight.
Then, mix both components thoroughly until the material becomes completely uniform. Stir carefully to minimize unnecessary air entrapment.
Afterward, pour the silicone slowly over the master model. Allow the material to cure at room temperature without disturbing the mould. Depending on temperature, humidity, mould thickness, and other conditions, demoulding typically takes approximately 12–24 hours.
Finally, remove the cured silicone mould carefully and inspect the reproduced details before beginning repeated casting.
Storage and Safety
Use suitable gloves and work in a clean, well-ventilated area. Avoid direct contact with eyes and skin, and follow the manufacturer’s safety recommendations for handling the components.
Moreover, keep the containers tightly closed when not in use. Store the product in a cool, dry environment and protect the components from unsuitable storage conditions.
