Industrial Grade Tin-Cure Liquid Silicone Rubber (LSR)
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. Mechanical Resilience
- Tear Strength: 45–60 kN/m (ASTM D624) for 500+ demolding cycles, ideal for intricate geometries like floral bas-reliefs or modular tile patterns.
- Flexural Endurance: Shore A 20–50 hardness range balances flexibility and structural support for large-scale concrete molds.
2. Efficient Processing
- Room-Temp Cure: 4–24 hr cure time (adjustable with catalysts) vs. platinum LSR’s 1–2 hr heat requirement.
- Low-Energy Production: No autoclaves needed; compatible with hand lay-up or vacuum casting for on-site fabrication.
3. Economic Viability
- Cost Savings: 30–40% cheaper than platinum-cure LSR at comparable volumes (bulk pricing <$25/kg).
- Extended Storage: 12-month shelf life in sealed containers at 15–25°C, reducing procurement frequency.
4. Environmental Stability
- Chemical Resistance: Withstands pH 3–11 exposure (e.g., alkaline concrete leachate, cleaning acids).
- Thermal Performance: Stable from -40°C to 200°C (±2% dimensional change), suitable for precast steam curing.
5. User Safety & Precision
- Non-Toxic Formulation: Meets EU REACH standards for manual handling; VOC emissions <50 ppm.
- Near-Zero Shrinkage: 0.1–0.2% linear shrinkage preserves sub-millimeter details (e.g., stone vein replication).
Applications in Architectural Mold Making
| Segment | Use Cases | Performance Benefit |
| Mass Production | Concrete pavers, modular wall systems | High tear resistance for 1,000+ casts |
| Custom Design | Heritage restoration molds, 3D facade panels | Captures 50μm surface textures accurately |
| Landscaping | Artificial boulders, fountain basins | UV stability for 5+ years outdoor use |
Comparison with Alternative Materials
- vs. Platinum LSR:
- Pros: Lower cost, better air release for bubble-free molds.
- Cons: Limited continuous heat resistance (>200°C degrades tin catalysts).
- vs. Polyurethane:
- Pros: 3× longer lifespan, superior chemical resistance to wet concrete.
- Cons: 20% slower cure time; requires mold release agents for PU master models.- vs. Platinum Silicone: Lower upfront cost but less suitable for high-heat applications (>200°C).
- vs. Polyurethane Rubber: Superior flexibility and longer lifespan, though slightly slower curing.
