Hi,
I am using 20% phosphoric acid as flux and love it after testing many other agents.
However, I am not happy with the wetting capability. I tends to form local drops on brass, even if the brass has been degreased with acetone before. Technically, it has a high contact angle on brass.
Is any of my fellow thunderers using a wetting agent with phosphoric acid to improve wetting?
I have been testing ox bile, but the result looks ghastly.
As some may know, I am not UK based, so brand names won't help much.
thanks for your input.
