Momentive RTV159 Electronic Potting and Sealing Silicone Adhesive

Basic Properties

Product Introduction

Momentive RTV159 is a high-strength, red silicone sealant designed for industrial applications requiring exceptional thermal stability and electrical insulation. As a one-component RTV (Room Temperature Vulcanizing) material, it cures upon exposure to ambient moisture, forming a durable elastomer that maintains elasticity across extreme temperatures (-60°C to +205°C). Its acetic acid release during curing ensures rapid cross-linking, while its adhesion to metals, glass, ceramics, and plastics without primers simplifies deployment in critical sealing tasks

Enhanced Special Properties

RTV159 distinguishes itself through three core attributes:

• ​High-Temperature Resilience: Retains structural integrity and elasticity at sustained temperatures up to 205°C, outperforming standard silicones (typically rated ≤150°C)
• ​Universal Adhesion: Bonds to diverse substrates (e.g., metals, plastics, ceramics) without primers, validated by MIL-A-46146B certification for military-grade electrical insulation
• ​Structural Stability: Exhibits low shrinkage during curing, high tensile strength, and resistance to creep under mechanical stress, ensuring long-term sealing in high-vibration environments

Application Scenarios

RTV159 is engineered for demanding electrical and industrial sealing:

• • ​Electronics & Electrical: Sealing capacitors, resistors, and PCB components exposed to high temperatures or thermal cycling; UL HB flammability certification ensures safety in electrical enclosures
  • ​Industrial Maintenance: Repairing leaks in high-temperature pipelines (e.g., fuel lines, steam systems), sealing transformers, and rebuilding mechanical keyways
  • ​Automotive & Aerospace: Gasket sealing for engine compartments, exhaust systems, and avionics where thermal shock resistance is critical
