Product Overview
Momentive TSE397 B/W is a single-component, condensation-curing silicone adhesive/sealant. It rapidly cures upon exposure to ambient moisture to form elastic silicone rubber. Designed with flowability, it suits fine filling and coating of electronic components. It provides non-corrosive adhesion to metals (copper, aluminum), plastics, ceramics, and glass without primer pretreatment. Compliant with military standard MIL-A-46146B, it releases low-odor alcohol vapor during curing, ensuring environmental friendliness.
Special Properties
- Non-Corrosive Adhesion: Certified by MIL-A-46146B, zero corrosion on sensitive metals (e.g., copper), ensuring long-term reliability of electronics
- Rapid Curing: 10-minute tack-free time and 24-hour full cure, enhancing production efficiency
- Environmental Resistance: Operates from -50°C to 200°C, withstanding ozone, chemicals, and harsh conditions
- Electrical Insulation: High volume resistivity (1.0×10¹⁵ Ω·cm) and dielectric strength (18 kV/mm), providing insulation for electronic devices
- Flowability: Fills micro-gaps (≤0.5 mm), ideal for precision sealing in micro-sensors and PCB traces
Application Scenarios
-
Electronic Component Sealing:
- Conformal coating for PCBs (moisture/dust/corrosion protection), sensor encapsulation, waterproofing of junction boxes
-
Industrial Bonding:
- Structural adhesion for metal/glass/plastic/wood (e.g., automotive brackets, instrument housings)
-
Telecommunication Equipment:
- Waterproof sealing for 5G base station modules and fiber optic interfaces, enhancing outdoor durability
