Industrial Grade Tin-Cure Liquid Silicone Rubber (LSR)
Introduction
Tin-Cure Liquid Silicone Rubber (LSR) is a versatile and
cost-effective material widely used in craft and architectural mold
making. It has excellent flexibility, durability and ease of use,
making it the first choice for artists, DIY enthusiasts and
architectural professionals.
Main features of Tin-Cure LSR
1. High flexibility and tear resistance
- Suitable for complex molds (e.g. sculptures, decorative tiles).
- Withstands repeated demolding without cracking.
2. Fast cure (Room temperature vulcanization, RTV-2)
- Room temperature cure (typically 4-24 hours) reduces production
time.
3. Non-toxic and skin safe
- Safer for hobbyists than platinum-cured silicone (no risk of
contaminants inhibiting cure).
4. Economical for small batches
- More economical than platinum silicone, ideal for small-scale
mold projects.
5. Good chemical and weather resistance
- Suitable for outdoor architectural molds (e.g. concrete
decoration, facade design).
Applications in crafts and architecture
- Art and DIY: jewelry, resin art, soap molds, candlesticks.
- Architecture: custom concrete molds, decorative columns, 3D wall panels.
- Prototyping: architectural model making, landscape design models.
Why choose tin-cured LSR over other alternatives?
- Compared with platinum silicone: lower cost, but poorer heat
resistance (optimal temperature below 200°C).
- Faster cure and better dimensional stability compared to
condensation-cured silicone.
