What is a GASKET?

STARSHIELD® GS-SG6001A is a one component, electrically conductive silicone paste, cured by moisture in the air. The cured material is highly elastic and electrically conductive, and thus suitable for form-in-place gasketing application in EMI shielding. The material offers excellent shielding effectiveness and good adhesion to various conductive substrates including metallized plastics, die-cast, and metallic substrates.


  • - One component, moisture cure material
  • - Rheological stability : No metal-sedimentation during storage
  • - Short handling time of 2 hours
  • - Excellent and stable electrical conductivity
  • - Good adhesion to various conductive substrates
