Shin-Etsu KE-441 One-Component RTV Self-Leveling Sealant - High-Performance
Basic Product Attributes
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.
Product Description
KE-441 is designed for applications requiring rapid curing and high elasticity. Its self-leveling properties make it ideal for precision electronics sealing and form-in-place gasketing (FIPG). Cures in 7 days at 23°C/50% RH with a tack-free time of 60 minutes.
Special Features
Electrical: Volume resistivity 5 TΩ·m, dielectric strength 20 kV/mm for insulation. Mechanical: Tensile strength 1.7 MPa, elongation 280%, hardness 20 Shore A. Temperature range: -40°C to +180°C.
Applications
Applications include automotive electronics sealing, LED encapsulation, medical device bonding, and industrial gasketing. Low volatility and non-corrosiveness suit sensitive electronics.
