The Kester 44 is a is an activated rosin formula for use in flux-cored solder wire. 44 has virtually dominated the field of activated rosin core solders for well over five decades. An outstanding performance feature of this flux is the “instantaction” wetting behavior. The high mobility and fast-spreading action of this flux results in more reliable production linesoldering. Under IPC J-STD-004, 44 is classified as ROM1. Despite the increased activity and soldering performance, 44passes both 85°C/85% RH and 40°C/90% RH SIR test methods.

Kester 44 Features:
  • High activity RA formulation
  • Excellent solderability to a wide variety of metalizations
  • Industry standard RA cored wire for decades
  • Classified as ROM1 per J-STD-00
