Glyptol was a General Electric product. It was used extensively for motor and transformer windings, and did it's job very well. Otis Elevator used it for general painting of car frames, machine room,? and hoistway equipment as well. It is very durable, remains glossy over the years, protects against rust, but is also rather brittle. It chips away from an impact site or drilled hole like porcelian enamel on a kettle, and is difficult to grind away if you need to weld or solder.? I was told the original was discontinued because of environmental concerns.

G.E. is no longer into it... and Glyptol is now a brand (for at least a couple decades)... and like a famous de-oxidising snake oil (not really for snakes: either the plumbing kind... or the reptile kind) ... anyway... like that product's marketing ... Glyptol (the company) has diversified the name Glytol (the product) over their copious product line... so much so that no one knows ... I claim... just what one means by Glyptol anymore.
The original Glyptol was a kind of alkyd polymer ... available both as an oil based paint, to let air dry... and available as a theromsetting polymer, by baking it ... it became much harder and much more durable coating. (I'd go more into the chemistry... but some people in this forum fear chemicals more than they fear the devil... so to speak.)
Yes. I believe when G.E. developed Glyptol (or it was developed for them) that Glyptol was a superior product for manufacturing, at least, motor windings.
