has anyone used sylgard 184 / 182 as a binder ? (a common silicone used for sealing photo cells to generate electricity)

it was suggested as a binder for an illumination flare in 1968 based on magnesium / sodium nitrate composition.

it should also protect the maganesium quite well from moisture.

maybe useful instead of pban / htpb in apcp rocketry ?

anyone used it ?

I have not, but GE Silicone II (GE280 and GE5000) is said to work & is not a 2 part mix.
I bought a couple tubes @ a local hardware store & intend to try it as a binder.

Ammonium perchlorate..............................63
Silicone II.......................................22
Copper(II)oxide...................................10
PVC...............................................5
