Product Introduction
RTV167 is a high-strength, gray silicone adhesive sealant designed for demanding electronic applications. As a one-component, moisture-curing material from Momentive Performance Materials, it forms a resilient rubber at room temperature. Its unique alkoxy cure system releases minimal alcohol vapor during curing, ensuring non-corrosive protection for copper, brass, and other electronic metals. Certified to UL E-36952 and compliant with MIL-A-46146 specifications, RTV167 combines robust performance with industrial reliability.
Enhanced Properties
RTV167 surpasses standard silicone sealants with exceptional mechanical strength (56 kg/cm² tensile, 600% elongation) and adhesion (10 kg/cm peel strength). Its electrical insulation properties include a dielectric constant of 2.8 @ 60 Hz and ultra-high volume resistivity (3×10¹⁵ ohm-cm), critical for preventing leakage currents. The sealant maintains elasticity from -60°C to 204°C and resists environmental degradation from UV, ozone, moisture, and chemicals. Notably, it cures fully in 48 hours for 3mm sections under standard conditions (25°C/50% RH), but thicker applications (>6mm) are not recommended due to extended cure kinetics.
Application Scenarios
- Aerospace: Sealing avionics components and sensor modules.
- Automotive: Bonding engine control units (ECUs) and ignition systems.
- Electronics: Potting high-voltage transformers and protecting PCB copper traces.
