Addition Cure Platinum Silicone Rubber 40 Shore A 1:1 Mixing Low Shrinkage 0.1% for Concrete GRC Molds Factory Supplier

Shenzhen Hanast New Material Co., Ltd. is a direct addition cure silicone rubber manufacturer and B2B factory supplier of high-performance two-component platinum-catalyzed RTV silicone rubber engineered specifically for architectural concrete molds, GRC (Glassfiber Reinforced Concrete) casting, and cultural stone production. With a 40,000-square-meter production base and multi-ton batch capacity, we serve construction material factories, precast concrete manufacturers, and architectural ornament producers worldwide.

Our E-Series HN-E40-AS addition cure silicone features an ultra-low shrinkage rate of only 0.1%, ensuring exceptional dimensional accuracy and precise mold reproduction for large-scale architectural casting projects. The 1:1 easy mixing ratio minimizes operational errors, making it suitable for both manual pouring and automated dispensing systems in industrial production environments.

• Ultra-Low Shrinkage 0.1% - Industry-leading dimensional stability ensures faithful reproduction of fine surface details in cultural stone, decorative wall panels, and architectural ornaments
• 1:1 Simple Mixing Ratio - Accurate two-part mixing with minimal room for error, ideal for both small workshops and high-volume automated production lines
• Two-Component Addition Cure System - Platinum-catalyzed curing generates no byproducts, delivering consistent batch-to-batch performance with superior mechanical properties
• 40 Shore A Hardness - Optimal balance of rigidity and flexibility for large concrete molds, preventing deformation under heavy material loads
• Wide Temperature Range -40°C to +230°C - Stable performance across extreme conditions for cold climate outdoor casting and high-temperature resin applications
• High Transparency - Translucent formulation enables easy visual monitoring of mold quality and accepts color pigmentation per customer specifications

• GRC Panel Production - High-precision molds for glassfiber reinforced concrete facade elements and lightweight architectural components
• Cultural Stone Casting - Exceptional surface detail reproduction for artificial cultural stone, decorative wall panels, and architectural ornaments
• Concrete Paver & Tile Manufacturing - Long-life molds for repetitive concrete paver, block, and tile production in commercial settings
• High-Gloss Epoxy Resin Casting - Suitable for large epoxy resin river tables and decorative ornaments requiring mirror-finish surfaces
• Plaster & Sandstone Relief Molds - Multi-piece brush-on molding for flat or large three-dimensional components exceeding 50 cm
