Your impression would be incorrect. Some Greeks had been wearing composite cuirasses (linen or leather and scale or lamellar together in the same cuirass), but that was very uncommon in the east and was mostly favoured around the Italian peninsula. Alexander famously wears a composite cuirass on the Alexander Mosaic, of course, but this is the latest and farthest eastern example known to me.

And why not ? Scale is good. As metal armour goes it's pretty cheap and cheerful to make and easy to maintain, and gives good protection. Plus you can make it out of quite a few other materials as well.
Why not? Because the wearing of scale cuirasses in the east is not borne out by the archaeological evidence. Linen or leather cuirasses were cheaper to make than metal armour of any kind, and even then it's very apparent that Greek artisans preferred metal muscled cuirasses to any other kind.

Given the extant local infrastructure and workforce skilled in making that sort of armour, the Seleucids and Bactrians would have had to be crazy to not make use of it as well.
You'll have to provide some evidence for the "infrastructure and workforce skilled in making that sort of armour."
