We have added the silicone adhesive and sealant "TSE398" to AD-Chemi.
The Momentive product "TSE398" is a one-component, fast-curing, non-corrosive silicone adhesive sealant that cures with moisture in the air. After curing, it forms an elastic silicone rubber and exhibits excellent adhesion to copper, various metals, plastics, ceramics, glass, and more without the need for a primer. It has high fluidity and is designed for easy injection, making it widely applicable from waterproof sealing of electrical and electronic devices to general adhesive applications.
- Non-corrosive: Complies with MIL-A-46146B corrosion testing.
- Safe to use on highly corrosive metals such as copper and brass.
- Fast curing: Tack-free time is only 10 minutes (at 23°C).
- Low odor: Releases alcohol vapors during curing (significantly less odor compared to acetate-based products).
- Primerless adhesion: Direct adhesion to a wide variety of substrates is possible.
- Wide temperature range: Suitable for high and low temperature environments from -55°C to +200°C.
- Excellent weather resistance, ozone resistance, and chemical resistance.
- Outstanding electrical insulation properties: Ideal for sealing high-voltage components.
