Optimized Technical Introduction for Industrial Grade

Tin-Cure Liquid Silicone Rubber (LSR)

Superior Material for Architectural Mold Making

RTV-2 tin-cured liquid silicone rubber (LSR) delivers exceptional performance in producing high-durability molds for concrete, plaster, and silicone-based architectural components. Engineered for precision and resilience, it is the optimal choice for fabricating decorative elements such as patterned wall tiles, ornate Roman columns, and intricate relief panels

High-Strength Tin-Cured LSR for Architectural Molds – Durable & Cost-Effective


Key Properties of Tin-Cured LSR
1. Ultra-Low Shrinkage (<0.2%)
- Ensures dimensional stability and accurate replication of fine surface textures (e.g., stone grain, floral motifs) without post-curing deformation.
- Critical for large-scale modular molds requiring seamless assembly.

2. Enhanced Tear Resistance & Thermal Stability
- Withstands 200°C processing temperatures, making it compatible with hot-cured concrete and gypsum.
- Robust mechanical properties reduce mold damage during demolding, extending service life by 30–50% compared to conventional rubbers.

3. Chemical Inertness in Harsh Environments
- Resists alkalis (pH 12+), acids, and moisture—ideal for outdoor applications or chemically aggressive substrates like Portland cement.
- Prevents degradation from mold-release agents or cleaning solvents.

4. Cost-Efficiency for Mass Production
- 40–60% lower material cost than platinum-cure LSR, with comparable detail fidelity for non-medical applications.
- Room-temperature curing reduces energy consumption in manufacturing.

Applications in Architectural Mold Making

- Prefabricated Architectural Elements: Reusable molds for GFRC facades, cultural heritage restoration.
- Landscape Hardscaping: High-cycle production of pavers, balustrades, and faux-stone veneers.
- DIY/Artisan Use: User-friendly for small-batch artisan crafts with minimal equipment.
