MEK is a cancer causing agent.
It has a low boiling point and is very flammable.

Subject: [TN] Flux Removal with MEK


TechNetters - some of our assembly techs use MEK to remove flux. I know MEK
is potent and probably shouldn't be used for flux removal. What I need is
some justification WHY we shouldn't use MEK.

We are soldering 22 gauge stranded wire to connector lugs and microswitch
turret terminals. This assembly is part of a fuel control for commercial
fanjet engines. We use Sb5WS (Tin 94%, Lead 0.2%, Antimony 4-6%) solder and
Kester 197 Flux, which is type RMA.

Any help is appreciated.

Regards,
