40 Shore A Platinum Cure Silicone Rubber for Large Scale Concrete Mold Making

The 40 Shore A Platinum Cure Silicone Rubber is a two-component, addition-curing liquid silicone rubber specifically engineered for large-scale concrete component molds and architectural cultural stone casting applications. With its optimal 40 Shore A hardness, 1:1 mixing ratio and extremely low shrinkage rate (≤0.1%), this platinum-cured silicone delivers exceptional dimensional stability for heavy-duty industrial mold making.

Key Features

  • 40 Shore A Hardness: Provides the ideal balance of rigidity and flexibility for large concrete molds, preventing deformation under heavy material loads during casting of cement and concrete components.
  • 1:1 Mixing Ratio: Simple and accurate two-part mixing with minimal room for error, suitable for both manual pouring and automated dispensing systems in industrial production environments.
  • Ultra-Low Shrinkage ≤0.1%: Ensures precise mold reproduction and superior dimensional accuracy for architectural casting projects, preserving fine surface details.
  • High Tear Strength 19 kN/m: Superior durability for repeated demolding cycles, reducing mold replacement frequency in high-volume production settings.
  • Wide Temperature Range -40°C to +230°C: Stable performance across extreme conditions, suitable for both cold climate outdoor casting and high-temperature resin applications.
  • Non-Toxic and Eco-Friendly: Platinum-catalyzed curing system generates no byproducts, meets FDA food contact and medical-grade compliance standards.

Applications

  • Large Concrete Component Molds: Ideal for casting heavy cement and concrete architectural elements, maintaining precise geometric shape even under substantial compressive loads.
  • Architectural Cultural Stone Casting: Perfect for producing artificial cultural stone, decorative wall panels and architectural ornaments with exceptional surface detail reproduction.
  • High-Gloss Epoxy Resin Casting: Suitable for large epoxy resin river tables, decorative ornaments and art pieces requiring mirror-finish surfaces with precise mold parting lines.
  • Plaster and Sandstone Relief Molds: Multi-piece brush-on molding for flat or large three-dimensional components exceeding 50 cm with moderate pattern complexity.

Available Hardness Range

The E-Series offers a full hardness spectrum from 0 to 60 Shore A , allowing mold makers to select the optimal flexibility for their specific application. Custom formulations available upon request.

Packaging and Storage

  • Standard packaging: 10Kg/set (A 5Kg + B 5Kg), 40Kg/set (A 20Kg + B 20Kg)
  • Custom packaging options available for bulk orders
  • Store in a cool, dry place away from direct sunlight
  • Shelf life: 12 months in original sealed packaging
