Thermotech TE™ is a Silver-filled, electrically conductive high-vacuum compound specifically manufactured by Pure Tech for the sputtering target industry. Thermotech TE combines the excellent thermal and electrical conductive properties of pure Silver with a low vapor pressure sealant, enabling it to withstand high vacuum operating ranges. Thermotech TE contains no Silicone, and is non-hardening. Furthermore, Thermotech TE absorbs grease and chemical impurities on metal surfaces, and cleans up easily with solvents such as methanol or acetone, leaving surfaces virtually contamination-free after use.
Thermotech TE is applied along the contact surfaces of the sputtering target and cooling plate in systems that are indirectly water-cooled. Because it is a viscous sealant, Thermotech TE fills small scratches and surface imperfections better than Indium foil, dramatically increasing target cooling. Since it is electrically conductive, Thermotech TE will not hinder DC sputtering operation.
