WACKER ELASTOSIL N2199 90ml – Silicone for Bonding and Sealing in Technical Applications, MIL-A-46146, Shore A 30

ELASTOSIL N2199 is a one-component RTV-1 silicone with a neutral curing system, designed for demanding bonding and sealing applications in industry, electronics, and modern technical systems. The material cures in contact with moisture from the air, forming a durable, flexible, and resilient joint that maintains its properties even during long-term use in challenging environmental conditions.

The product exhibits excellent adhesion to a wide range of substrates, including metals, glass, ceramics, and selected plastics, often without the need for a primer. Its thixotropic consistency prevents sagging, allowing precise application on vertical surfaces and in automated processes, including FIPG (Formed-In-Place-Gasket) technologies.

ELASTOSIL® N2199 demonstrates high thermal resistance from –45°C to +180°C, as well as excellent resistance to moisture, aging, UV radiation, and environmental factors. This makes it ideal for both indoor and outdoor applications where stability and long-lasting sealing performance are essential. The neutral curing system minimizes the risk of corrosion on sensitive components, which is particularly important in electronics and precision mechanical assemblies.

The product meets MIL-A-46146 standards, confirming its quality and suitability for applications requiring high reliability. Additionally, ELASTOSIL® N 2199 provides good electrical insulation properties, allowing safe use near electrical and electronic components.
