Gregg,
It depends.  There are  a wide range that we use, depending on the 
application and the customer requirements.  We use several silicones, but 
those may not meet the outgassing requirements for space.  We have some 
urethanes, but they may not have the flammability characteristics required 
by FAA for commercial flight hardware.  We have some other adhesives, but 
may not meet the fungus resistance reqiurements for military applications 
(hence my recent question).  Epoxies are very nice, unless you want to 
rework them, then they ain't. 

The most frightening comment I ever heard came from a senior VP in design 
engineering who asked why don't we just use materials with no drawbacks. 
For one of the few times in my life, I was speechless.  Leave it alone 
Dewey.

Subject
[TN] Component Staking Adhesive






Dear Technetters:

A general survey question as to what type of adhesive you use to stake 
components to survive Aerospace/Space applications?

Thanks in advance.
