LOCTITE SI 5421 is an alkoxy-based silicone adhesive designed for automotive sensor bonding and gasketing of EMI/RF shielded enclosures. This one-component paste requires no mixing and cures at room temperature (RTV). Once cured, it forms a flexible, electrically conductive bond and can also act as a form-in-place gasket.
LOCTITE SI 5421 Features:
Technology: Alkoxy silicone
Type: One-component, no mixing required
Curing Method: Room Temperature Vulcanizing (RTV)
LOCTITE SI 5421 Applications:
Automotive Industry: Bonding automotive sensors and gasketing for EMI/RF-shielded enclosures
Electronics Manufacturing: Creating flexible, electrically conductive bonds and shielding against electromagnetic interference
Other Applications: Form-in-place gaskets for RF/EMI shielding enclosures, electrical insulation, and vibration damping
