Momentive TSE397K-C is a one-component, fast-cure, non-corrosive, clear silicone adhesive sealant. It cures upon exposure to atmospheric moisture to form an elastic silicone rubber and exhibits excellent primerless adhesion to a wide variety of substrates.
This product complies with MIL-A-46146B, ensuring it is non-corrosive to metals. Its thixotropic paste consistency allows for easy application, and it features low odor, releasing alcohol vapor during cure. The cured rubber from TSE397K-C offers excellent resistance to high and low temperatures (from -55°C to 200°C), weather, ozone, and chemicals, along with outstanding electrical insulation properties.

A key special attribute of TSE397K-C is its exceptional electrical insulation, with a volume resistivity of 2.0x10¹⁵ Ω·cm and a dielectric strength of 22 kV/mm. Additionally, it features a fast tack-free time of approximately 10 minutes at 23°C. Its low hardness (Shore A 13) and high elongation (360%) indicate a very soft and elastic cured material capable of effective stress relief.
Based on its properties, Momentive TSE397K-C is well-suited for insulating adhesive sealing and fixing of electrical and electronic parts, such as encapsulation in power modules, sensors, and control units. It is also commonly used as a waterproof sealant for electrical, electronic, and communication equipment, and as a general adhesive for metals, glass, and plastics. Its clear color (-C) is particularly advantageous for applications requiring visual inspection or aesthetic considerations.
