MacDermid Alpha Introduces ALPHA® EF-2100 VOC-Free, Zero-Halogen Liquid Soldering Flux

(Waterbury, CT USA) – December 18th, 2019 – The Assembly division of MacDermid Alpha Electronics Solutions, a world leader in the production of electronics soldering and bonding materials, has introduced ALPHA® EF-2100, their latest VOC-free, zero-halogen liquid soldering flux designed to meet current REACH and RoHS legislation.

“ALPHA EF-2100 shows stable performance compared to EF-2210, Alpha’s leading VOC-free flux,” said Bernice Chung, Global Portfolio Manager for Wave Solder Assembly Solutions.  “The solderability of this product has shown to be equivalent in hole-fill, solder balling and bridging while providing good lead-free solder joint cosmetics with an evenly spread, tack-free residue.”

This Tetraglyme-free flux contains zero rosin, low solids, no-clean chemistry and is Bellcore and SIR compliant.  ALPHA EF-2100 is a drop in replacement for users of EF-2210, EF-2202, WB-400 & NR-300 who wish to use a non-toxic product. 

More information on ALPHA Liquid Soldering Fluxes, including ALPHA EF-2100, can be found on our website along with the ALPHA Flux Selector Tool which was designed to help customers choose the right wave soldering flux for their challenging processes.
