Product Overview

Momentive RTV162 is a white, spreadable silicone paste designed to cure at room temperature when exposed to atmospheric moisture.

Unlike acidic silicone sealants, RTV162 uses a non-corrosive neutral cure system. This makes it particularly suitable for sensitive electronic applications involving copper, brass, circuit boards and electrical connections.

The material cures into a tough and resilient silicone rubber that maintains flexibility across a very wide temperature range.

Momentive RTV162 Silicone Sealant 82.8ml is supplied in the 3TG tube format, making it convenient for maintenance, aerospace, electronics production, prototype assembly and controlled manual dispensing.

Key Features and Advantages

Non-Corrosive Electronic Grade Silicone

RTV162 is specifically designed for electronic applications and is non-corrosive to electronic metals including copper and brass.

This characteristic makes it suitable for circuit boards, electronic connections and sensitive electrical assemblies where conventional acidic silicone sealants may create corrosion concerns.

Excellent Electrical Insulation

The cured silicone provides strong dielectric performance.

Its typical dielectric strength is approximately 18 kV/mm and its volume resistivity is approximately 3 × 10¹⁵ ohm-cm, making it suitable for insulation and protection around electrical and electronic components.

Wide Temperature Performance

Momentive RTV162 Silicone Sealant 82.8ml maintains flexible elastomeric properties at low and high temperatures.

The official technical data lists a brittle point of approximately -60°C and a maximum continuous operating temperature of approximately 204°C.

Short-term exposure may reach approximately 260°C under suitable conditions.

High Flexibility

The cured RTV162 silicone has a typical elongation of approximately 400%.

This flexibility allows the sealant to absorb vibration, thermal expansion and mechanical movement without forming a rigid brittle bond.

Environmental Protection

RTV162 provides excellent resistance to moisture, dust, dirt, UV, ozone and many chemicals.

It can therefore help protect electronic components and connections in demanding industrial, automotive, appliance and aerospace environments.

One-Component Application

No resin, hardener or mixing process is required.

The product can be dispensed directly from the tube and cures through atmospheric moisture, simplifying maintenance and production processes.

Applications

PCB Component Bonding

Momentive RTV162 Silicone Sealant 82.8ml is suitable for securing capacitors, resistors, integrated circuits and other components to printed circuit boards.

Electronic and Integrated Circuits

RTV162 can provide flexible bonding and environmental protection around integrated circuits, semiconductor devices and sensitive electronic components.

Connectors and Exposed Wires

The silicone can be used to seal connectors, exposed wires and electrical interfaces where moisture and contamination protection are required.

Aerospace and Avionics

Momentive lists RTV162 among its aerospace and aviation adhesive technologies. It is suitable for selected avionics, electrical boxes, cockpit instruments and related high-performance applications.

Automotive Electronics

The combination of temperature stability, vibration resistance and electrical insulation makes RTV162 useful for selected automotive electronic assemblies.

Appliances and Industrial Equipment

The product can also be used for electrical and electronic components incorporated into household appliances and industrial equipment.
