GENERAL DESCRIPTION
Momentive TSE3402 is an exceptional two-component, addition-cure liquid silicone rubber specifically developed for high-precision industrial mold making. When mixed with its corresponding curing agent, the compound cures reliably at room temperature to form a high-strength, high-hardness elastic rubber. This material solves critical production bottlenecks for design engineers by eliminating dimensional inaccuracies and ensuring the faithful replication of intricate component details.
This product is officially distributed in Vietnam by Prostech, complete with comprehensive technical support and tailored solutions for your manufacturing processes.
FEATURES & BENEFITS
- Excellent Dimensional Stability:** Ensures that cured molds maintain strict form factors and exact shapes over extended production cycles without distorting.
- Excellent Release Characteristics:** Enables smooth and effortless separation from the master model and cast parts, decreasing cycle times and protecting delicate geometric details.
- Low Shrinkage (Room Temperature Cure):** Offers minimal cross-linking shrinkage during its room temperature cure cycle, securing tight tolerances for the finished mold.
- High Strength and Hardness:** Formulated to achieve a durable 60 Type A hardness and a 17 N/mm crescent tear strength to withstand rugged, repetitive industrial use.
TYPICAL APPLICATIONS
- Used in the assembly process and complex design replication within arts, crafts, and architectural interiors.
- Ideal for solving mold degradation issues in manufacturing production lines dedicated to the fabrication of buttons and detailed casting items.
- Prostech provides application testing and technical consulting for these use cases to maximize efficiency and prevent potential cure inhibition from incompatible substrate contaminants like sulfur, amines, or paints.
