Momentive Tse397 B/W LSR Silicone Sealant For Dual Color Molded Parts

Momentive Tse397 B/W LSR for Dual-Color Molded Parts

Product Properties

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

1. Non-Corrosive Adhesion: Certified by MIL-A-46146B, zero corrosion on sensitive metals (e.g., copper), ensuring long-term reliability of electronics
2. ​Rapid Curing: 10-minute tack-free time and 24-hour full cure, enhancing production efficiency
3. ​Environmental Resistance: Operates from -50°C to 200°C, withstanding ozone, chemicals, and harsh conditions
4. ​Electrical Insulation: High volume resistivity (1.0×10¹⁵ Ω·cm) and dielectric strength (18 kV/mm), providing insulation for electronic devices
5. ​Flowability: Fills micro-gaps (≤0.5 mm), ideal for precision sealing in micro-sensors and PCB traces

Application Scenarios

1. Electronic Component Sealing:

   • Conformal coating for PCBs (moisture/dust/corrosion protection), sensor encapsulation, waterproofing of junction boxes 
      

2. ​Industrial Bonding:

   • Structural adhesion for metal/glass/plastic/wood (e.g., automotive brackets, instrument housings)

3. ​Telecommunication Equipment:

   • Waterproof sealing for 5G base station modules and fiber optic interfaces, enhancing outdoor durability
