Benefits of Adhesive Technology
Stress Resistance, Simplification, Economy
and More
One of the primary benefits of adhesive is that
it holds something together resisting the stress trying to pull it
apart.
Tensile Stress is exerted equally over the entire joint straight and away from the
adhesive bond.
Shear stress is across the adhesive bond. The bonded materials are being forced
to slide over each other.
Cleavage stress is concentrated at one edge and exerts a prying force on the bond.
Peel stress is
concentrated along a thin line at the bond's edge. One surface is
flexible.
Most applications combine stresses. The
following 6 points elaborate on the advantages of using adhesives for
stress resistance and more.
- Uniform distribution of stress over the entire
bonded area can eliminate
stress concentration caused by rivets, spot welds, and
similar mechanical fastening. Lighter, thinner materials can
often be used without sacrificing strength.
- Bonding laminates of dissimilar materials
can produce combinations superior in strength and performance to
either adherent alone. Adhesive flexibility compensates for
differences in coefficients of expansion.
 Elastomeric flexibility
improves resistance
to vibration fatigue.
- Holes are eliminated maintaining the
integrity of the bonded material. This can reduce
finishing and increase design flexibility.
- Continuous contact between mating
surfaces can effectively bond and seal
against many environmental conditions.
- Costs can be lowered by reducing
materials requirements and weight; eliminating drilling, welding,
screwing, and similar operations.
Choice of 3M Structural or Non-Structural Formations

systems.
Structural adhesives
bond the load-bearing parts of a product. Usually these are metal,
but wood, glass and rigid products can also be structurally bonded ...
