Fastening & Assembly Solutions & Technology July 2012

The complex sealing pattern created during cam cap sealing on the
Ford Sigma Engine is achieved using 5182 anaerobic sealer applied
with a robot.
By comparison hard gasketing carries a variety of Ford production
rules with regard to surface finish and is therefore a
much more demanding technology to apply. And another
plus point for RTV is reduced inventory over conventional
gaskets.
Better stress distribution is also an important performance
benefit of Loctite gasketing and this has a positive effect on
warranty. It requires much lower clamping forces than a
compression gasket that tends to relax under dynamic load
and decrease in thickness, with subsequent loss of bolt tension
in the flange joint and the potential for leakage.
Henkel’s relationship with Ford now spans forty years. It
is Ford’s preferred single source supplier of industrial adhesives
and sealants for engine production throughout the
world. It’s a great accolade for this manufacturer of the
Loctite brand and testimony to the performance of its products.
But more than that it is the result of Henkel’s characteristic
focus on customer support that allows companies such
as Ford to continuously push the boundaries of technology
and gain competitive edge.
