Sylgard 184 / 182 as a binder

[dave321]

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
