Tough adhesive July 1st 2008 Available from Henkel, Loctite 278
is a high strength threadlocking
adhesive that is both oil tolerant
and resistant to elevated
temperatures. Being anaerobic, it
cures when confined in the
absence of air between close fitting
metal surfaces. Once cured, it
prevents loosening and leakage
caused by shock and vibration.
Fixture time for Loctite 278 on
M10 nuts and bolts is generally 10
to 15min. Full cure depends on the
substrates and the bond gap.
Although intended for use on
permanent joints, disassembly is
possible, achieved through the
application of localised heat in
excess of 250°C to the nut or bolt,
then applying a torque. More articles from Henkel Ltd: |
