Product Introduction
Momentive TSE399 is a one-component RTV silicone that cures rapidly
by reacting with atmospheric moisture to form a soft dielectric
rubber. Its flowable consistency ensures thorough coating around
complex assemblies, with fast tack-free time (10 min), broad
temperature resistance (-55°C to 200°C), and superior electrical
insulation (dielectric strength 20 kV/mm). Non-corrosive to metals
and exhibits outstanding adhesion to most plastics.
Advanced Characteristics
- Deep Cure Efficiency: Full cure achieved in 72 hours for 2mm thickness at 25°C/50% RH
(per "Bonding" section).
- Environmental Resistance: Withstands UV, ozone, moisture, and chemicals (per "Key
Features").
- Electrical Excellence: Dielectric constant 2.9 (60 Hz), dissipation factor 0.005 (60
Hz), volume resistivity 2×10¹⁵ ohm-cm (table data).
- Compliance: Meets MIL-A-46146A* corrosion resistance (*excludes hydrolytic
stability).
Application Scenarios
- High-Density PCB Coating: Flowable consistency protects fine-pitch components against
shock, moisture, and electrical leakage (Source: Electronics
Manufacturing Tech Forum).
- Solar Junction Box Sealing: Weather resistance and dielectric strength ensure long-term
reliability in PV systems (Source: Solar Component Supplier
Report).
- Automotive Sensor Encapsulation: Maintains sealing integrity under extreme temperatures
(-55°C~200°C) (Source: Automotive Electronics Whitepaper).
