dumb flux antimony question

ronron Member Posts: 143
i thought i remember reading they are wanting to phase out antimony in solder (and fluxes) and things are going towards tin/silver/copper with no antimony. is that true?
reason i ask is i have a tub of nokorode 95/5 pre-tinning flux which is antimony, and my solder is silvabrite 100 (tin/silver/copper no antimony). so after thinking about what i actually have, should i consider changing the flux i am using? or should i keep using the nokorode?
thanks.

    Some of the older fluxes burn before you hit the melting point of the new solder blends. Check the operating temperature of the flux. Is this for heating use or potable water?

    I still like 50/50 for heating solder. Or Bridgit which flows like 50/50

    no such thing as a dumb ?.I find water based flux(utility)at least i think its water based stand to be corrected burns to fast before my solder so I stick with my Hercules which I have been using for years.Again everyone has their preferences but a good question.

    Hercules is what I use as well.
    This exact stuff. I find it to work much better than the garbage they sell at home improvement stores.
