Momentive RTV6424 Heat-Curable Silicone Adhesive Sealant

Fundamental Properties

Product Profile

Key Features and Typical Benefits

Beyond basic bonding and sealing, RTV6424 excels in demanding applications due to its special attributes. Its outstanding electrical properties (Dielectric Strength 500 V/mil, Volume Resistivity 1.0x10¹⁵ Ω.cm, Dielectric Constant 2.9, Dissipation Factor 0.003) make it ideal for electronics and electrical potting and insulation. The cured silicone exhibits excellent flexibility (Elongation up to 550%) and moderate hardness (Shore A 30), effectively absorbing stress and accommodating thermal expansion differences between substrates. Its broad adhesion range and primerless capability (Adhesion to Al of 300 psi) significantly streamline processes and improve efficiency. Furthermore, its wide thermal range performance and low shrinkage ensure dimensional stability and sealing reliability over long-term use.

Application Scenarios

Momentive RTV6424 is particularly suited for applications requiring high-performance bonding, sealing, potting, or insulation:

• ​Automotive Electronics:​​ Bonding, sealing, and insulating protection for sensors in the engine compartment (e.g., oxygen sensors, knock sensors), requiring resistance to high temperature, vibration, and chemical exposure.
• ​Power Electronics:​​ Encapsulation and insulation of power modules (e.g., IGBTs), capacitors, and connectors, providing electrical isolation, gap filling (silicone has moderate thermal conductivity), and moisture protection.
• ​Industrial Electronics:​​ Component bonding, conformal coating protection, and housing sealing for control boards and drives.
• ​Photovoltaic Modules:​​ Bonding, sealing, and potting of internal components in junction boxes, protecting them from environmental degradation.
• ​General Industrial Sealing & Bonding:​​ Non-electronic device or metal/non-metal substrate bonding/sealing requiring long-term reliability, wide temperature resistance, and weatherability.
