Shin-Etsu KE-3418 High-Temperature Sealant/Adhesive for Heating
Elements & Extreme Heat
Product Introduction of Shin-Etsu KE-3418
Basic Product Attributes
Shin-Etsu KE-3418 is a one-part, room-temperature cure, thixotropic
silicone adhesive/sealant that forms a tough and durable elastomer
after curing, with exceptional high-temperature resistance. It
features low odor, neutral cure, and non-corrosive properties,
offering excellent unprimed adhesion to metals, plastics, glass,
and ceramics.
Product Description
KE-3418 is designed for high-temperature applications, withstanding
intermittent exposure up to 315°C, outperforming standard
high-temperature silicone materials. Its unique chemistry ensures
long-term stability under extreme conditions while maintaining
mechanical and electrical properties. It cures in 7 days at
23°C/50% RH with a tack-free time of 5 minutes, ideal for rapid
processing.
Special Properties
- Heat Resistance: Intermittent use at 315°C, continuous range from
-40°C to +250°C.
- Electrical Properties: Volume resistivity 1 TΩ·m, dielectric
strength 20 kV/mm, suitable for electronics.
- Mechanical Properties: Tensile strength 2.00 MPa, elongation 200%,
hardness 45 Shore A.
- Eco-Friendly: Low VOC, non-corrosive, compliant with industrial
standards.
Applications
Applications include sealing heating elements, industrial ovens,
automotive exhaust components, and high-temperature protection for
electronics. Its reliability is also proven in aerospace and energy
sectors.
