Hard Disk Drive


Please click here to redirect to the new 3M™ Novec™ site.

3M™ Novec™ Engineered Fluids are excellent in meeting the demanding cleaning requirements of the hard disk drive industry. These fluids are used for cleaning light oils and particulate from many parts of the drive, including MR heads, HGAs, suspensions and media. Typically used in vapor degreasing equipment or specialized cleaning machines with ultrasonic agitation.

The low surface tension of Novec fluids allows greater penetration than conventional solvents, providing outstanding cleaning performance on both metallic and non-metallic parts – even in tight spaces and complex configurations. Their low heat of vaporization ensures rapid drying after the cleaning process.


Use of Novec fluids offers a meaningful reduction of greenhouse gas emissions compared to HFC's and is not targeted for emission reduction by the Kyoto Protocol.
