I need to know which of the various high-heat thermal paste should be used that will maintain re-bonding the heating tube to the heating plate. The manufacturer did not use thermal grease as it appears it will not maintain the bond between the heating tube and the heating element. They instead used a vertically stable paste that assumes a hardened consistency of chalk to best maintain the bond in the presence of water. However, I have yet to find the proper paste which bonds while tolerating the sufficient intermittent high heat ratings required. The manufacturer has been unable to provide any assistance or information. Can you please tell me what material to use in this circumstance. Thanks KB.
