Shin‑Etsu KE‑40RTV Silicone Sealant 330 mL Neutral Cure RTV for Industrial & Electrical Use

About Shin-Etsu KE-40RTV Silicone Sealant

OVERVIEW:

Shin-Etsu KE-40RTV is a one-component, room-temperature vulcanizing (RTV) silicone sealant designed for general-purpose sealing, bonding, and coating applications. It cures upon exposure to atmospheric moisture to form a flexible, durable silicone elastomer. KE-40RTV is formulated to provide reliable adhesion and long-term performance across a wide range of substrates and environmental conditions, making it suitable for use in industrial, electrical, automotive, and building applications.

KEY FEATURES:

Room-Temperature Cure
Cures under ambient temperature and humidity without requiring external heat, enabling convenient application in various environments.

Broad Temperature Resistance
Performs across a typical service temperature range of -40°C to +180°C, helping to maintain sealing integrity under thermal cycling.

Good Adhesion
Adheres to a variety of substrates, including metals, glass, ceramics, and plastics, supporting flexible application across different industries.

Weather and UV Resistance
Resistant to moisture, ozone, and ultraviolet (UV) exposure, supporting use in outdoor and demanding environments.

Flexible and Durable Seal
Forms an elastic silicone rubber that accommodates joint movement, thermal expansion, and vibration without cracking or loss of adhesion.

APPLICATIONS:

• Electrical and Electronics – Used for sealing and insulating electrical enclosures, cable entries, and sensitive electronic assemblies.

• Industrial Equipment – Suitable for bonding and sealing in machinery and production equipment exposed to vibration and temperature variations.

• Automotive Components – Applied in gasket sealing, body panel bonding, and other automotive assembly and repair applications.

• Building and Construction – Used for general sealing of windows, doors, joints, and facades where weather resistance and flexibility are required.

PACKAGING:

Shin-Etsu KE-40RTV is commonly supplied in standard cartridges (approx. 330ml) for manual or pneumatic application. Other packaging formats may be available depending on supplier and region.

INSTRUCTIONS FOR USE:

• Surface Preparation: Ensure surfaces are clean, dry, and free from dust, oil, and residues to promote good adhesion.

• Application: Apply the sealant directly onto prepared surfaces. Tool the sealant within the skin-over time specified in the product datasheet.

• Curing: Allow to cure under room temperature and humidity. Full cure time depends on the thickness of the applied sealant and environmental conditions.

SAFETY AND HANDLING:

Shin-Etsu KE-40RTV should be used in a well-ventilated area. Avoid direct contact with eyes and prolonged skin exposure. Use protective equipment such as gloves and goggles during application. Refer to the product’s Safety Data Sheet (SDS) for complete safety and handling information.
