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

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

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.
