ANTI-SEIZING AGENT

PURPOSE:To obtain an anti-seizing agent which is applied to a bolt or nut to be used in a high-temperature and high-vacuum environment to prevent seizure and enable smooth attaching and detaching by using a specified alkyl- substituted tetraphenyl ether and boron nitride as the constituents. CONSTIT...

Beschreibung
Zusammenfassung:	PURPOSE:To obtain an anti-seizing agent which is applied to a bolt or nut to be used in a high-temperature and high-vacuum environment to prevent seizure and enable smooth attaching and detaching by using a specified alkyl- substituted tetraphenyl ether and boron nitride as the constituents. CONSTITUTION:An anti-seizing agent which contains an alkyl-substituted tetraphenyl ether (A) (having one to four 6-20C substituents) and 20-70wt.% boron nitride (B) having a mean particle diameter of 0.1-50mum. The ether to be used as the base oil has higher thermal stability than other lubricating oils and evaporates little even at high temperature. The nitride to be used as the additive is stable at high temperature, and the incorporation thereof in a suitable amount can give an anti-seizing agent exhibiting excellent performance under high-temperature and high-vacuum conditions.
