RTV Silicone Adhesive Sealant Momentive Rtv157 High Temp Resistant

Momentive Rtv157 High-Temp Resistant RTV Silicone Adhesive & Sealant

Product Properties

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:

1. ​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
2. ​Electrical Insulation:
   • Withstands >20 kV/mm dielectric strength, suitable for high-voltage components
3. ​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:

1. 1. ​Industrial Equipment Sealing:
      • Seals pumps, valves, and compressors in chemical processing plants, resisting acid/alkali corrosion
   2. ​Electronics & Electrical Encapsulation:
      • Protects PCB components, sensors, and high-voltage connectors from moisture and mechanical shock
   3. ​High-Temperature Environments:
      • Bonds exhaust systems, engine gaskets, and aerospace components (e.g., satellite assemblies
