It's fascinating stuff...

I don’t think there is ammonia in Stan’s sealant. It doesn’t smell like it nor is it listed on the MSDS. If ammonia were used, it could cause the precipitation of latex because the CO2 would react with the ammonia to form ammonium carbonate but that would suggest avoiding using CO2 entirely. If you are making home brew with ammonia, I’d avoid using CO2 entirely.
