sorry if this is in the wrong section, please adjust if necessary

does anyone know if there would be a preferred binder for thermite type blends ?
the idea would be for a small "slab" to be used for document destruction (instead of using the old cross cut shredder ).

i am aware of the "castable" aluminium/ plaster of paris mixtures

any alternative low gassing compositions suggestions ?
i dont think ignition would be a problem using a lead oxide silicon prime (basically a non gassy delay)

i've seen some patents using silicone as a low viscosity binder, to create flexible sheets.

nitrocellulose perhaps ?

any ideas anyone

I have used thermite in nitrocellulose for my silver stars with a pretty good result.

hmm ?

wouldnt want that dross to fall on me, it pretty hot stuff.
would think conventional star formulas to be more appropriate

The stars ignite 100 meters or so up in the air, so there is no molten iron when it finally comes down.

I don't think you need a binder at all if you just want to use the thermite as thermite, just some kind of box or can.

PBAN is used as a binder for thermate, similar but not the same thing.
Why wouldn't good old dextrin work?

I have experimented with an artists binder called Mowelith 60 along with a plasticizer (dibutyl phthalate) to make flexible thermalite fuse. Got promising results, but got sidetracked before I reached any very profound conclusions!

Dan Williams has some stuff about it here:

Don't know if that's of any help...
