ShinEtsu KE-441 Silicone Sealant 330ML, High Temp Resistance 180°C
Shin-Etsu KE-441 is a one-component, room-temperature curing, self-leveling silicone adhesive that forms a tough elastomer. It features low odor, neutral cure, non-corrosiveness, and excellent unprimed adhesion to metals, plastics, glass, and ceramics.
- Self-leveling properties ideal for precision electronics sealing
- Excellent for form-in-place gasketing (FIPG) applications
- Cures in 7 days at 23°C/50% RH with 60-minute tack-free time
- Electrical insulation properties: 5 TΩ*m volume resistivity, 20 kV/mm dielectric strength
- Mechanical properties: 1.7 MPa tensile strength, 280% elongation, 20 Shore A hardness
- Wide temperature range: -40°C to +180°C
Ideal for:
- Automotive electronics sealing
- LED encapsulation
- Medical device bonding
- Industrial gasketing
Low volatility and non-corrosiveness make it suitable for sensitive electronics applications.
