Having some new sash windows being put in - the fitter is priming them

I'm interested if it exists; an equivalent Acrylic top coat similar in
ware and durabilty to gloss.

Acrylic gloss is only fit for interior use at present. Decorators like
the acrylic undercoat (or often acrylic primer undercoat) because it
means they can get two coats (undercoat and gloss) applied in a day
and the gloss can dry overnight.
