Product Introduction
Momentive TN3005 is a one-component, low-volatility siloxane-based silicone adhesive sealant. It cures at room temperature upon exposure to atmospheric moisture and exhibits primerless adhesion to diverse substrates including metals, glass, and engineering plastics. Key features include fast tack-free time (7 minutes), UL94 HB flame retardancy, and low alcohol emission during cure.
Enhanced Properties
- Low Volatility: Volatile siloxane (D3-D10) content ≤0.01 wt%, minimizing contamination risks in sensitive electronics.
- Corrosion Safety: Non-corrosive to metals (Na⁺/K⁺/Cl⁻ impurities <2 ppm).
- Adhesion Performance: Cohesive failure achieved on 15+ substrates (e.g., metals, epoxy, PC, nylon), except non-polar plastics like PE/PTFE.
- Electrical Insulation: High volume resistivity (2.0×10¹⁵ Ω·cm) and dielectric strength (26 kV/mm) suit high-voltage applications.
Application Scenarios
- Electronics Protection: Waterproof sealing for communication equipment enclosures, PCB potting, and sensor encapsulation.
- Industrial Adhesion: Bonding/fixing of metal housings, glass lenses, and plastic components in automotive sensors.
- Specific Case: Verified use in LED driver encapsulation (IP67 rating) and battery module sealing in IoT devices (per industry reports).
