High-intensity, medium-intensity, and low-intensity threadlocker
sealing of threaded fasteners. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. Typical applications include the locking and sealing of large bolts and studs (M25 and larger). The thixotropic nature of jom 262 reduces the migration of liquid product after application to the substrate.
Detailed introduction
Product Description
JOM 277E is a high strength, anaerobic thread
locking compound. JOM 277E is designed for the
permanent locking of threaded fasteners. The
product performs on aluminum, steel, plated fasteners, stainless steel, and special alloy parts. JOM 277E exhibits good temperature stability and is solvent resistant.
Typical Applications
JOM 277E will lock and seal large fasteners.
JOM 277E is used in applications where shock and vibration may cause the fastener to loosen.

Instructions for Use
Ensure parts are clean, dry and free from oil and grease.
Compatible Primers
Primers such as JOM 7649 (Primer N) or JOM 7641 (Primer T) can be used to speed the fixture time of
the adhesive. Fixture times can improve by as much as 50%. The use of primers can result in lower
strength and performance should be tested after full cure.
