Product Introduction
Momentive RTV162 is a one-component, electronic-grade silicone adhesive sealant that cures to a resilient rubber at room temperature upon exposure to atmospheric moisture. It is UL-recognized (File E-36952), non-corrosive to copper/brass, and releases low-odor alcohol vapor during curing. Designed for ease of application, it maintains performance across -60°C to 204°C continuous operating temperatures.
Advanced Properties
RTV162 excels in mechanical durability with 35 Shore A hardness and 400% elongation, providing superior flexibility under stress. Its 550 psi tensile strength outperforms standard electronics sealants (e.g., RTV160: 275 psi), while maintaining high dielectric stability (3×10¹⁵ ohm·cm resistivity). The paste consistency enables precise dispensing without sagging, and its 7-day full cure ensures reliable bonding in humid environments.
Application Scenarios
- PCB Component Bonding
Securing capacitors/connectors on automotive control modules (e.g., Tesla battery management systems).
- Copper Trace Protection
Conformal coating for high-voltage busbars in solar inverters (SMA, Sungrow).
- Aerronics Sealing
Avionics enclosure gasketing in Boeing 787 thermal management systems.
- Industrial Sensors
IP67 sealing for MEMS sensors in ABB robotics joints.
