A METHOD OF MIXING AN ADDITIVE WITH A SOLVENT FOR LUBRICATION OF MAGNETIC RECORDING MEDIA

摘要

A process for mixing a hexaphenoxycyclotriphosphazene or phosphazene derivative additive with a perfluorohexane or fluorocarbon solvent to create a mixture is disclosed. The additive and solvent are mechanically or thermally mixed under certain conditions effective to substantially dissolve the additive in the solvent. Also disclosed is the resulting composition and a process for adding the resulting additive/solvent mixture to an additive-depleted luber bath during manufacturing to replenish the additive concentration in the bath.
