Momentive TSE392 Silicone Sealant Electrical Component Protection and Insulation

Product Properties

Product Introduction

Momentive TSE392 is a high-performance, one-component, room-temperature vulcanizing (RTV) silicone product that functions as an adhesive, sealant, and coating. Renowned for its convenience, outstanding electrical insulation properties, and wide operating temperature range, it is specifically engineered for demanding electrical and electronic applications. TSE392 utilizes a unique crosslinking chemistry, curing to form a soft, dielectric silicone rubber that is non-corrosive to metallic substrates. Its thixotropic paste consistency allows for easy application, enabling the formation of thicker coatings or precise gap filling in complex assemblies without sagging. Upon opening, it cures rapidly at room temperature by reacting with atmospheric moisture (tack-free time approximately 5 minutes), requiring no mixing or de-airing, making it exceptionally user-friendly.

Enhanced Technical Attributes

The core strengths of TSE392 lie in its exceptional combination of properties: Firstly, its electrical properties are outstanding, featuring very high volume resistivity (2.00 x 10¹⁵ ohm-cm), excellent dielectric strength (22 kV/mm), and an extremely low dissipation factor (0.0050 @ 60 Hz), making it an ideal insulation and protection material. Secondly, it boasts a wide temperature stability range (-55°C to 200°C), maintaining its elastomeric properties under extreme high and low temperatures, effectively resisting thermal and mechanical shock. Thirdly, it provides a reliable protective barrier with excellent resistance to moisture, UV, ozone, and chemicals, ensuring long-term reliability. Fourthly, it exhibits excellent adhesion to a wide range of substrates, including various plastics. Fifthly, its thixotropic paste nature is critical for applications requiring vertical application, dispensing, or forming thicker insulation layers (e.g., on high-voltage components). The cured material is clear (approx. 90% visible transmission, thickness not specified) or white, facilitating visual inspection. Furthermore, it meets the corrosion-resistant requirements of MIL-A-46146A and cures rapidly via atmospheric moisture (fast tack-free) with only a slight alcohol odor. Packaging in tubes or cartridges ensures convenience in dispensing and usage.

Application Scenarios

Based on its excellent electrical insulation, environmental sealing protection, wide temperature stability, and thixotropic properties, Momentive TSE392 is ideally suited for the following applications:

• ​Potting and Coating of Electrical/Electronic Components:​​ Providing comprehensive protection against moisture, contamination, shock/vibration, and high-voltage insulation for printed circuit boards (PCBs), sensors, coils, capacitors, connectors, etc. Particularly suitable for high-voltage components (e.g., transformers, ignition coils) requiring localized thick coating or coverage over complex shapes.
• ​Bonding Requiring Environmental Sealing:​​ Bonding and sealing sensor housings, instrument cluster components, lighting fixtures, metal/plastic enclosure joints, etc., providing reliable air/water tight barriers.
• ​Automotive Electronics:​​ Protecting engine compartment modules, control units, sensor connectors, etc., from high temperatures, vibration, oils, and moisture.
• ​Power Modules:​​ Used for insulating and protecting power devices and connection points inside AC/DC converters, inverters, and power modules.
• ​Industrial Control Equipment:​​ Sealing and protecting PLC modules, I/O modules, drives, etc., from dust, moisture, and chemicals in industrial environments.
• ​​(Supplemental Reference Applications - Inferred based on similar RTV properties):​​ Information indicates that similar thixotropic one-component RTV silicones (like TSE392) are commonly used for insulation protection at voltage sampling points in electric vehicle Battery Management Systems (BMS), internal sealing of solar PV junction boxes, and coating power electronic components requiring thick-layer insulation.
