Fast fixture time for structural adhesive?
(OP)
I am looking for an adhesive to bond two pieces of stainless steel sheet metal together. It is a vertical joint with a 0.5" x 0.5" bond area. The "hanging" component weighs 0.01 pounds.
I need a structural adhesive that can hold the 0.01 pounds almost instantly (within 5-6 seconds). Once it is applied and can hold the 0.01 pound component in place it will then be subject to 5 minutes at 250 deg F.
My biggest goal is to avoid any sort of clamping.

2) 95 deg F/95% humidity
3) -35 deg F cold

Would the hot melt be strong enough? To give you a better idea of the design there would be a 100 lbs of force being applied in shear to the 0.5" x 0.5" bond area. There is a slight peel requirement as well. We have found that an acrylic with 3400 psi shear combined with 23 pli peel has worked very well but we're back to the fixture time issue.

Way out of the box.
These people make some unique adhesives.

I suggest that you spot weld. It's fast and it'll be strong enough to meet your known requirements.

Thank you for your replies!
We are looking to replace spot welding. It needs to only hold 0.01 lbs within 5-6 seconds. Once the adhesive is cured (many of the adhesives I have found have a 24 hour cure time) it will then be subjected to the load and atmosphere I reference above.

Tell us what you've tried that does work, excluding cure time.

The adhesive you seek is commonly called a Pop Rivet.

Have you tried Dow Corning? Some of the silicone family of adhesives has remarkably good mechanical properties, especially in relatively thin film applications between two relatively rigid substrates. They're available with rapid thermal curing. I don't have the p/n's of the materials we used to use in the hybrid electronics industry, but these materials were qualified for the full military temperature range. We used a screen printable material as well as automated luer-lock syringe dispensers, both of which might be well suited to your high volume.
