Shin‑Etsu KE‑445 RTV Silicone Sealant 330 mL Neutral Cure, Self‑Leveling Adhesive Sealant for Industrial & Electrical Use

About Shin-Etsu KE-445 Silicone Adhesive Sealant

OVERVIEW:

Shin-Etsu KE-445 is a one-component, room-temperature vulcanizing (RTV) silicone adhesive sealant designed for bonding, sealing, and protecting components across a wide range of industries. It cures upon exposure to atmospheric moisture to form a flexible, durable silicone rubber. KE-445 is formulated for applications that require strong adhesion, excellent weatherability, and long-term reliability under thermal cycling and environmental exposure.

KEY FEATURES:

Room-Temperature Cure
Cures under ambient temperature and humidity without the need for external heat, simplifying the application process.

Wide Operating Temperature Range
Performs effectively from approximately -40°C to +200°C, supporting stable adhesion and sealing across varying thermal conditions.

Excellent Adhesion
Adheres well to a broad range of substrates including metals, glass, ceramics, and various plastics.

Weather and UV Resistance
Offers long-term resistance to moisture, UV radiation, ozone, and outdoor weathering, making it suitable for exposed environments.

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

APPLICATIONS:

• Electrical and Electronic Components – Used for bonding, sealing, and insulating components such as connectors, housings, and modules.

• Automotive Applications – Suitable for sealing gaskets, housings, connectors, and body panels exposed to thermal cycling and environmental stresses.

• Industrial Equipment – Applied in machinery, enclosures, and assemblies requiring flexible and durable sealing performance.

• Building and Construction – Used for general sealing of joints, gaps, and penetrations in windows, doors, facades, and HVAC systems.

• Consumer Electronics – Provides long-lasting sealing and protection in devices exposed to temperature and humidity variations.

PACKAGING:

Shin-Etsu KE-445 is typically supplied in standard cartridges (approx. 330ml) or larger containers depending on application requirements and regional availability.

INSTRUCTIONS FOR USE:

• Surface Preparation: Clean surfaces thoroughly to remove dust, oil, and contaminants to ensure optimal adhesion.

• Application: Apply the sealant directly to prepared surfaces. Tool the sealant within the specified skin-over time to ensure proper seal formation.

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

SAFETY AND HANDLING:

Shin-Etsu KE-445 should be used in a well-ventilated area. Avoid contact with eyes and skin. Use appropriate protective equipment such as gloves and goggles. Refer to the product’s Safety Data Sheet (SDS) for complete safety, handling, and disposal guidelines.
