Product Introduction
Momentive RTV11 is a two-part, solvent-free silicone elastomer cured with dibutyl tin dilaurate (DBT). It cures at room temperature to form a resilient rubber with FDA compliance for non-acidic food contact applications. Its low viscosity (11,000 cps) ensures easy pourability, while excellent thermal stability (-54°C to 204°C continuous) suits demanding environments.
Advanced Characteristics
RTV11’s unique 20.3 kV/mm dielectric strength and 1.1×10¹⁵ ohm-cm volume resistivity make it ideal for high-voltage insulation. With only 0.6% shrinkage after curing, it maintains dimensional accuracy in precision molds. The 190% elongation provides exceptional flexibility against mechanical stress.
Application Scenarios
Validated industry applications include:
- Potting of aerospace sensors: Protects circuitry against thermal cycling (-65°F to 400°F) per SAE AS23053 standards.
- Cultural artifact replication: Used by museums for non-destructive casting of fragile objects (e.g., Smithsonian Institution case study).
- Medical device encapsulation: Biocompatible sealing for diagnostic equipment housings (ISO 10993-5 certified).
