Momentive TSE397K-C Fast-Cure Adhesive Sealant for Electronic Components
Momentive TSE397K-C is a one-component, fast-cure, non-corrosive, clear silicone adhesive sealant that cures upon exposure to atmospheric moisture to form an elastic silicone rubber. It exhibits excellent primerless adhesion to a wide variety of substrates.
Product Overview
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 offers excellent resistance to high and low temperatures (from -55°C to 200°C), weather, ozone, and chemicals, along with outstanding electrical insulation properties.
