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

Industrial Grade Tin-Cure Liquid Silicone Rubber (LSR)

RTV-2 tin-cured LSR is ideal for creating durable concrete, plaster, and silicone molds for decorative elements such as wall tiles and Roman columns.
It offers low shrinkage (<0.2%), strong tear resistance, and can withstand temperatures up to 200°C, ensuring precise reproduction of details.
Its resistance to acids and alkalis makes it suitable for harsh construction environments.
It is more cost-effective than platinum-cured silicones, making it ideal for large-scale architectural mold production.

Key Properties of Tin-Cured LSR
1. Excellent Flexibility & Tear Resistance
- Withstands repeated demolding without damage, ideal for complex architectural designs (e.g., ornamental concrete, geometric panels).
- Maintains shape integrity even under stress, ensuring consistent mold reproduction.

2. Fast and Easy Curing Process
- Cures at room temperature (typically 4–24 hours), reducing production downtime compared to heat-cured silicones.
- No specialized equipment needed, making it accessible for small workshops or on-site projects.

3. Cost-Effective for Large-Scale Use
- More affordable than platinum-cured silicones, suitable for budget-conscious builders and manufacturers.
- Long shelf life (6–12 months) minimizes material waste.

4. Chemical & Weather Resistance
- Resists moisture, UV rays, and mild acids/alkalis, ensuring longevity for outdoor molds (e.g., garden statues, façade elements).
- Performs well in temperatures up to 200°C (392°F), suitable for precast concrete and resin applications.

5. Non-Toxic and User-Friendly
- Safe for skin contact during manual application, unlike some industrial mold materials.
- Low shrinkage (<0.2%) preserves fine details in molds.

Applications in Architectural Mold Making
- Concrete Casting: Columns, balustrades, decorative tiles, and paving stones.
- Facade & Wall Panels: Intricate 3D designs, bas-reliefs, and textured surfaces.
- Landscaping: Reusable molds for garden ornaments, fountains, and artificial rocks.
- Restoration: Replicating historical architectural elements with precision.

Comparison with Alternative Materials
- 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.
