Shin-Etsu KE-45-T Silicone Sealant 330ml Neutral Cure RTV-1 for Electrical and Industrial Use

About Shin-Etsu KE-45-T Silicone Sealant

OVERVIEW:

Shin-Etsu KE-45-T is a one-component, room-temperature vulcanizing (RTV) silicone sealant designed for industrial bonding, sealing, and coating applications. It cures upon exposure to atmospheric moisture to form a flexible, durable silicone rubber. KE-45-T is known for its excellent adhesion to a wide range of substrates and its ability to maintain performance under varying environmental conditions, including high temperatures and humidity. It is suitable for both assembly line production and general maintenance applications.

KEY FEATURES:

Room-Temperature Cure
Cures at ambient temperatures without the need for additional heat, simplifying processing and application.

Wide Service Temperature Range
Maintains flexibility and sealing properties across a broad temperature range, typically from -40°C to +200°C, with short-term peaks up to +250°C depending on system conditions.

Excellent Adhesion
Adheres well to many materials, including metals, glass, ceramics, and various plastics, supporting versatility in application.

Weather and UV Resistance
Offers stable performance under outdoor exposure, helping to resist degradation from sunlight, ozone, and moisture.

Flexible and Durable Seal
Forms an elastic silicone rubber seal that accommodates thermal expansion, mechanical vibration, and movement between jointed materials.

APPLICATIONS:

• Electrical and Electronic Equipment – Used for sealing, insulating, and protecting components and assemblies.

• General Industrial Bonding – Suitable for bonding dissimilar materials where flexibility and environmental resistance are required.

• Automotive Applications – Applied in sealing flanges, housings, and joints exposed to high temperatures and vibration.

• Building and Construction – Used for sealing gaps, joints, and penetrations in metal panels, glass assemblies, and exterior surfaces.

PACKAGING:

Shin-Etsu KE-45-T is typically available in standard cartridges (approx. 330ml) for use with manual or pneumatic dispensing equipment. Additional packaging formats may be available depending on distributor and regional supply.

INSTRUCTIONS FOR USE:

• Surface Preparation: Clean all application surfaces to remove dust, oils, and residues to promote optimal adhesion.

• Application: Apply the sealant directly to the prepared surfaces. Tooling should be performed within the skin-over time specified in the product datasheet.

• Curing: Allow the sealant to cure under ambient temperature and humidity conditions. Full cure time depends on joint thickness and environmental factors.

SAFETY AND HANDLING:

Use Shin-Etsu KE-45-T in well-ventilated areas. Avoid contact with eyes and prolonged skin exposure. Appropriate protective equipment, such as gloves and goggles, is recommended during handling. Refer to the product’s Safety Data Sheet (SDS) for detailed safety, handling, and disposal information.
