Quick question about Hysol.

Why does everyone use Hysol 9462?? The graph in the link below shows that 9462 is a "lower viscosity" form of 9460, yet 9460 has higher shear and peel strength.

AND the 9460F is a quick drying version of 9460 and has a higher tensile, sheer, AND peel strength.

I'm just wondering?? Is 9460 too thick to work with??

The layman in me thinks the thicker, stronger hysol would be a better choice. Input appreciated.

I have used 9460F for a long time, years.

I've used a multitude of Hysol products including the ones you list. I've even used them as filler in some spots. I had a control horn rip out of a foam control surface at a jet rally, put some quick set hysol in there and flew an hour later with no issues at all. Great glues.

Where can I get Hysol? I'd like to give it a try.

Hysol 9462 is milky white.
Hysol 9460 F is grey.
So when you doing the white fuse. Grey will easy see from outside when sunlight go through the fuse.
Also milky white look cleaner from the inside than grey.

McMaster Carr sells it. They always have it in stock. You will need to purchase the applicator gun and some mixing nozzels.

I have it, I was just curious why people mostly use the 9462.

Probably because 9462 was (is?) the original BVM Aeropoxy. Bob Violett picked it for everybody!

Thanks Philo.

They are pretty pricey comparatively speaking. Dreamworks and several others have it for less.

When using that chart or any other adhesive chart. You have to remember they are doing the lap shear test using aluminum that has been media blasted, cleaned in acetone, dried with nitrogen, and possibly prepped with 1% silane solution. The numbers for a similar lap test using composites is much, much, lower.

It’s all about surface prep!!!! You must sand and clean the parts to be bonded. Then pick the Hysol product that has the properties you think are best for the application. Post curing the bond never hurt. I like to cook a new plane in my dark green trailer for a day, it gets to about 140 deg. F, before paint and final finish.
