Abstract
There are provided a sealing composition for a hard disk drive (HDD) motor and a HDD motor fabricated using the same. The sealing composition includes: 45 to 65 parts by weight of urethane methacrylate; 35 to 50 parts by weight of methacrylate; and 2 to 4 parts by weight of acrylic acid. A sealing composition having a new composition is used as a sealing material of a flexible printed circuit (FPC) adhering part of the HDD motor, whereby a haze phenomenon due to air leak and outgas at the FPC adhering part may be improved and reliability of a HDD motor may be enhanced due to a reduction in generation of the outgas of the adhering part.
