Long Term (Days - Weeks)
The limiting factor for long term performance at high temperatures (e.g. 125¡C) is an
oxidation phenomenon which affects those portions of the adhesive having A) exposure
to air (oxygen) and B) as route for the reaction products to escape. The process is
diffusion limited and therefore the oxidation affects a small portion of adhesive around
the perimeter of the bond line. Small parts or poorly bonded parts having air gaps
extending to the edge of the bond area (see cross section below, left) are more
susceptible to oxidation-related failure than well bonded assemblies (below, right).
Choice of adhesive thickness well exceeding the runout of flatness on the part
(especially rigid substrates), coupled with optimal assembly methods can help reduce
air gaps (as discussed in Section I) and increase the high temperature reliability.
The problem of gap filling or air entrapment in pairs of rigid parts assembled with the
adhesive also makes these parts more susceptible to the oxidation phenomenon.
Flexible materials having fully contacted bond areas are less susceptible to reduced
adhesion from the oxidation. the graph below displays data (lbs./in. peel adhesion vs.
time at condition) from peel tests with one-inch wide anodized aluminum foil bonded
with the adhesive to ceramic substrates. These samples showed no net peel adhesion
loss despite a few millimeters of oxidation around the perimeter of the bond line.
