Epoxy group microcapsule pre-coated threaded locking agent meets automotive industry standards.

JOM93 is a one-component solvent-based pre-coating adhesive containing epoxy microcapsules,

designed for securing and sealing threaded fasteners. When applied to threaded surfaces and dried, it forms an adhesive film that remains inert on the fastener. During assembly, the microcapsules rupture, allowing the resin to fill threaded gaps and cure into a thermosetting plastic with sufficient strength and toughness. This provides reliable locking, anti-loosening, and sealing performance for assembled fasteners.

Typical Applications

JOM93 prevents loosening through vibration to provide locking and sealing of threaded assemblies including but not limited to:

Ringgearbolts
Head bolts
Intake manifold bolts
Transmissionbolts
