Brushable RTV-2 Condensation Cure Silicone – High Viscosity Series

Application Overview: Engineered for the reproduction of large-scale models where pouring is not possible. Primary applications include cultural stone molds, GRC/GRG restoration, large statues, relief sculptures, and architectural decoration.

Technical Advantages:

• Thixotropic Behavior: The silicone maintains a high viscosity state to prevent sagging but flows smoothly under the shear stress of a brush, ensuring bubble-free application.

• Layering Capability: Bonds perfectly to itself between layers, allowing for the reinforcement of the mold with gauze or fiberglass cloth.

• Robust Physical Properties: High elongation and tensile strength ensure the mold serves a long production life, even with abrasive casting materials like concrete.

• User-Friendly: standard mixing ratio (typically 100:2 or 100:3 with catalyst) and adjustable working times.

Suggested “How to Use” Snippet (Optional)

• Mixing: Mix Part A (Silicone) and Part B (Catalyst) thoroughly at a ratio of 100:3.

• Application: Apply the first layer thinly to capture detail (print coat). Apply subsequent layers to build thickness (approx. 1mm per layer).

• Reinforcement: Embed gauze or fiberglass cloth between the second and third layers to increase mold durability.

• Cure Time: Allow 24 hours for full cure before demolding
