Description: Superior No. 135 is a Petrolatum-based soldering paste that contains a Rosin activator. The Petrolatum helps protect the solder joint against corrosive attack and the paste form insures that the flux stays put until soldering. Applications: Superior No. 135 is useful on most common metals except Aluminum and Magnesium. It is employed mainly in plumbing and maintenance applications. (No. 135 is available in 2-oz “hockey puck” jars, 1-lb. cans, and in 5-lb., 20-lb. and 40-lb. pails.) This flux has a two (2) year shelf life. Information provided by Superior Flux |
