Product Description
Fire Resistant UL 94 V-0 Platinum Cure Silicone Rubber for GRC & Architectural Concrete Molds
This 25 Shore A addition-cure RTV silicone rubber is engineered for architectural concrete molds, GRC (Glassfiber Reinforced Concrete) casting and cultural stone production. The fire resistant UL 94 V-0 formulation meets international flame retardancy standards, delivering superior safety for construction and industrial applications.
Key Features
- Fire Resistant UL 94 V-0 - Flame retardant formulation compliant with international safety standards for construction use
- Optimal 25 Shore A Hardness - Ideal balance of rigidity and flexibility for large concrete molds, preventing deformation under heavy material loads
- High Tear Strength 19 kN/m - Superior durability for repeated demolding cycles in high-volume architectural production
- Ultra-Low Shrinkage ≤0.1% - Precise mold reproduction preserving fine surface details of cultural stone and decorative panels
- Easy 1:1 Mix Ratio - Accurate two-part mixing for both manual pouring and automated dispensing systems
- Wide Temperature Range -40°C to +230°C - Stable performance for cold climate outdoor casting and high-temperature resin applications
- Non-Toxic & Eco-Friendly - RoHS and REACH compliant, platinum-catalyzed curing generates no byproducts
