Product Description

LOCTITE SI 5421 Automotive Sensor Bonding and Gasketing of EMI/RF Shielded is an alkoxy-based silicone adhesive in a tan paste form (uncured). This one-component product requires no mixing and cures at room temperature (RTV). Once cured, it forms a flexible, electrically conductive bond that can also act as a form-in-place gasket.

Features of LOCTITE SI 5421 Automotive Sensor Bonding and Gasketing of EMI/RF Shielded

  • Technology: Alkoxy silicone.
  • Type: One-component, no mixing required.
  • Curing Method: Room Temperature Vulcanizing (RTV).

Applications of LOCTITE SI 5421 Automotive Sensor Bonding and Gasketing of EMI/RF Shielded

LOCTITE SI 5421 is suitable for:

  1. Automotive Industry: Bonding automotive sensors and gasketing for EMI/RF-shielded enclosures.
  2. Electronics Manufacturing: Creating flexible, electrically conductive bonds and shielding against electromagnetic interference.
  3. Other Applications:
    • Form-in-place gaskets for RF/EMI shielding enclosures.
    • Use in environments requiring electrical insulation and vibration damping.
