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.
