Product Introduction
Momentive TSE-397-C is a one-component, fast-curing, non-corrosive silicone adhesive sealant in clear color. It cures upon exposure to atmospheric moisture to form an elastic silicone rubber with flowable consistency. Designed for industrial applications, it provides primerless adhesion to metals (copper, steel), plastics, glass, and ceramics while releasing low-odor alcohol vapor during curing.
Advanced Technical Properties
- Non-corrosive & Fast Cure
- Passes MIL-A-46146B corrosion test, safe for copper and sensitive metals.
- Achieves tack-free state in 10 minutes at 23°C (50% RH).
- Extreme Temperature Resilience
- Operates from -55°C to 200°C with retained elasticity.
- Electrical Insulation
- Volume resistivity: 2.0×10¹⁵ Ω·cm (exceeds industrial standards).
- UL 94 HB certified (File E56745).
- Primerless Adhesion
- Bonds directly to glass, ceramics, and most plastics (e.g., acrylic, epoxy, PC*) without primers.
Application Scenarios
- Waterproof Sealing in 5G Antennas
- Used by NEC Corporation for sealing RF modules in base station antennas (2022 case study).
- LED Driver Potting
- Applied in Panasonic industrial LED drivers for moisture resistance and vibration damping.
- Medical Device Encapsulation
- FDA-compliant sealing for non-implantable diagnostic equipment housings.
