Hard Disk Surface Lubricant

Contributing to the improvement of hard disk reliability

The hard disk surface lubricant "MORESCO PHOSFAROL" is a special lubricant that lubricates the gap between the magnetic disk and the magnetic head on a hard disk device. It protects the information recorded on the disk with a nano-level thin film and contributes to the improvement of hard disk reliability.


This product combines the features of phosphazene, which has excellent stability against acid catalysts and resistance to heat, with those of perfluoropolyether, which has water and oil repelling properties. It has gained the strong trust of hard disk manufacturers because it has the adhesiveness to prevent it scattering, even when the hard disk is rotating at high speeds, and also excellent heat resistance.
