    Product Introduction

    Momentive TN3405-C is a one-component silicone adhesive sealant designed for encapsulant applications. It cures at room temperature upon exposure to atmospheric moisture, eliminating the need for primers on many substrates. Key features include fast tack-free time (7 minutes at 23°C), low volatility, and minimal odor during cure, which releases only alcohol vapor. The cured product forms a clear elastic rubber with excellent electrical properties, such as high volume resistivity and low dissipation factor, making it suitable for sensitive electronic environments. Packaging is available in 333ml cartridges for easy application.

    Enhanced Properties

    Deepening the physical properties, Momentive TN3405-C exhibits low hardness (17 Type A) and high elongation (260%), which provide exceptional flexibility and durability for dynamic stress environments. Its adhesion strength of 0.8 MPa to glass and primerless adhesion to substrates like aluminum, copper, phenolic resin, and epoxy resin (as per adhesion performance table) ensure reliable bonding without additional surface treatment. The product operates effectively over a wide temperature range (-45°C to 200°C), with low volatile siloxane content (100 ppm) minimizing environmental impact during cure. Electrical properties, such as dielectric strength of 25 kV/mm and dissipation factor of 0.01 at 60Hz, make it ideal for high-insulation applications, while impurities (each <2 ppm for Na+, K+, Cl-) guarantee purity for sensitive components.

    Application Scenarios

    general applications for silicone encapsulants include potting and sealing in electronics.
