Momentive RTV162 White 300ml Electronic Grade Non-Corrosive Silicone Adhesive Sealant for PCB and Electrical Components

Momentive RTV162 White Silicone 300ml is a one-component, non-corrosive electronic-grade silicone adhesive sealant developed for bonding, sealing, insulating and protecting sensitive electrical and electronic components. The 300ml cartridge provides a convenient production-size package for PCB assembly, semiconductors, connectors, electrical equipment and industrial electronic applications.

Product Overview

Momentive RTV162 is a professional white silicone adhesive and sealant designed specifically for electrical and electronic applications.

The uncured material is a white spreadable paste that cures at room temperature when exposed to atmospheric moisture.

Unlike conventional acidic silicone sealants, RTV162 uses a non-corrosive cure system and is suitable for use around sensitive electronic metals such as copper and brass.

Momentive RTV162 White Silicone 300ml cures to form a tough, flexible silicone rubber that provides reliable adhesion, electrical insulation and protection from environmental exposure.

The 300ml cartridge format is particularly suitable for industrial manufacturing, repetitive assembly, dispensing equipment and applications where the smaller tube package does not provide sufficient material.

Key Features and Advantages

Non-Corrosive Electronic Grade Silicone

RTV162 is specifically formulated for electronic and electrical applications.

Its non-corrosive curing characteristics make it suitable for use around electronic components and metallic substrates where acidic silicone systems may cause corrosion concerns.

One-Part Ready-to-Use System

No resin, hardener or mixing operation is required.

Momentive RTV162 White Silicone 300ml can be dispensed directly from the cartridge, helping simplify production and reduce mixing errors.

White Spreadable Paste

RTV162 has a white, spreadable paste consistency.

The material remains in position during application and is suitable for bonding, sealing, gasketing and fixing components where a flowable silicone would be unsuitable.

Excellent Flexibility

After curing, RTV162 develops a typical elongation of approximately 400%.

This flexibility allows the silicone to absorb mechanical vibration, thermal expansion and dimensional movement between different materials.

Strong Mechanical Performance

Typical cured tensile strength is approximately 3.8 MPa or 550 psi.

The combination of strength and flexibility makes RTV162 suitable for electronic components that require durable but non-brittle bonding.

Electrical Insulation

RTV162 provides excellent dielectric properties.

Typical dielectric strength is approximately 18 kV/mm, while volume resistivity is approximately 3 × 10¹⁵ ohm-cm.

These properties make the material suitable for insulating and protecting electrical and electronic components.

Wide Temperature Capability

Momentive RTV162 White Silicone 300ml maintains useful elastomeric properties over a broad temperature range.

The typical brittle point is approximately -60°C, while maximum continuous operating temperature is approximately +204°C.

Momentive technical data also lists intermittent exposure capability up to approximately +260°C under appropriate conditions.

Applications of Momentive RTV162 White Silicone 300ml

PCB Component Bonding

RTV162 can be used for bonding capacitors, resistors, integrated circuits and other components to printed circuit boards.

Electronic Component Fixing

The material provides flexible component fixation while helping absorb vibration and thermal movement.

Semiconductors and Integrated Circuits

Its electrical insulation and non-corrosive characteristics make RTV162 suitable for selected semiconductor and integrated-circuit assemblies.

Connector Sealing

Momentive RTV162 White Silicone 300ml can be used around connectors and electrical interfaces to help provide environmental sealing.

Exposed Wire Protection

The silicone can be applied around selected exposed wires and terminals where moisture and electrical insulation protection are required.

Electrical Equipment

RTV162 is suitable for various electrical assemblies, instruments, control equipment and industrial electronics.

Aerospace and Avionics

Its broad temperature capability and electrical performance also make RTV162 suitable for selected aerospace and avionics applications where an approved silicone system is specified.

Suitable Substrates

Typical compatible substrates may include:

Metal
Copper
Brass
Glass
Ceramic
Silicone Rubber
Selected Rigid Plastics
Electronic Substrates

Actual adhesion should always be confirmed on the production substrate before mass use.
