Momentive TSE399 Flowable Silicone Adhesive for Electronics

Basic Properties

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

1. High-Density PCB Coating: Flowable consistency protects fine-pitch components against shock, moisture, and electrical leakage (Source: Electronics Manufacturing Tech Forum).
2. ​Solar Junction Box Sealing: Weather resistance and dielectric strength ensure long-term reliability in PV systems (Source: Solar Component Supplier Report).
3. ​Automotive Sensor Encapsulation: Maintains sealing integrity under extreme temperatures (-55°C~200°C) (Source: Automotive Electronics Whitepaper).
