Product Overview
Momentive RTV157 is a high-strength silicone adhesive and sealant designed for demanding industrial applications. It cures at room temperature via an acetic acid-release mechanism, forming a robust elastomer with exceptional mechanical resilience. Its combination of high tensile strength (6.2 MPa), extreme elasticity (825% elongation), and strong adhesion (1.3 MPa) makes it ideal for structural bonding and sealing where durability is critical. The product exhibits excellent electrical insulation (volume resistivity >10¹⁴ Ω·cm) and resistance to environmental stressors like UV radiation and temperature extremes
Enhanced Properties
RTV157 distinguishes itself through three core attributes:
- Mechanical Superiority:
- High Tear Resistance (16.1 Kg/cm): 40% higher than standard RTV silicones, preventing crack propagation under stress
- Elasticity & Toughness: 825% elongation accommodates substrate thermal expansion/vibration without failure
- Electrical Insulation:
- Withstands >20 kV/mm dielectric strength, suitable for high-voltage components
- Environmental Resilience:
- Stable performance across -40°C to +150°C; resists UV degradation for decades
Application Scenarios
RTV157 is validated in the following high-stress fields:
- Industrial Equipment Sealing:
- Seals pumps, valves, and compressors in chemical processing plants, resisting acid/alkali corrosion
- Electronics & Electrical Encapsulation:
- Protects PCB components, sensors, and high-voltage connectors from moisture and mechanical shock
- High-Temperature Environments:
- Bonds exhaust systems, engine gaskets, and aerospace components (e.g., satellite assemblies
- Industrial Equipment Sealing:
