We've come out with a new recoil booster grease that is phenomenal.
Most recoil booster assisted suppressors employ ported pistons. That porting allows flash (or flame) into the recoil booster chamber which cooks the grease, baking or carbonizing it to the recoil booster body's wall. That heat & pressure also causes some of the grease to migrate forward onto the backside of the baffles, carbonizing onto those baffles robbing a little heat transfer efficiency and decreasing that suppressor's efficiency (in heated state most greases lose viscosity and then flow more easily being pushed forward by expansion gas pressure).
I had gone through about 6-7 synthetic greases that the respective manufacturers had indicated would not carbonize. Well, I have seen too many suppressors where the baffles have been caked with carbon & the inside of the recoil booster looking like the back side of a 1970s car engine exhaust valve (back when we used leaded gas) with built up carbon caked to the walls.
Ended up visiting the R&D labs of two major chemical manufacturing facilities here in Richmond to show their engineers our recoil booster and finally have a grease that is incredible.
Where other greases would last maybe 50 - 75 shots before being cooked or blown out of the booster body, this stuff does not migrate and definitely does not burn, cook or carbonize at the temps it is exposed to in a suppressor. That has it's obvious advantages - no carbon baking onto the booster wall, it's easier to clean and piston life goes way up. But no grease carbonizing to the baffle surfaces mean they don't lose efficiency.
After 490 rounds thru one can that I had just lubricated with the new grease, the booster body wall was still coated, albeit under a coating of carbon particles from the powder residue, but the grease had not migrated forward - it shows total imperviousness to the heat environment and pressure in a silencer.
And interestingly - all that is required to clean is hitting it with some MEK. This grease literally seems to vaporize at the sight of MEK - not quite but hopefully you get the idea. It really melts down fast and out it comes with all the powder residue that accumulated and no carbonization on the baffles, none, nada, zilch.
