Silver-Filled Paste for Target Sealing

Silver-Filled Paste

Made specifically for sputter targets.

This viscous sealant fills small scratches and surface imperfections better than indium foil, often dramatically improving target cooling.

  • A mixture of low vapor pressure vacuum fluid and silver powder
  • Combines excellent thermal/electrical conductive properties with high vacuum compatibility
  • No silicone-based material
  • Does not harden
  • Can be removed with methanol or acetone to leave a virtually contamination-free surface
  • Its electrical conduction makes it perfect for DC sputtering

CONTENTS:

  • Each jar contains sufficient paste to coat a 5″ x 15″ rectangle or a 10″ diameter circle
  • Includes utensils for applying and spreading the paste

DIRECTIONS: Apply the silver-filled paste to the contact surfaces between the back of the sputter target and cooling plate.

NOTE: Do not use silver-filled paste on ceramic or porous metal targets.
