Wire Enamel: Polyvinyl Formal and Cresol Resin in Solvent, Jackson and Hall 1938
GE's 1938 magnet-wire enamel: 10.67 % polyvinyl formal and 5.33 % cresol-formaldehyde resin dissolved in cresol and a hydrocarbon solvent, stirred until clear and viscous, then filtered. Wire drawn through it and baked at 250–500 °C, several passes, gets a tough, flexible insulation. We use benzene, one of the solvents the patent allows.

CC0 Isizinda Somphakathi
Le blueprint ikhishwe ngaphansi kwe-CC0. Ukhululekile ukukopisha, ukuguqula, ukusabalalisa, nokusebenzisa ngaphandle kwemvume.
Sekela uMenzi ngokuthenga imikhiqizo nge-Blueprint yabo IKhomishane Yomenzi kumiswe ngabathengisi, noma dala inguqulo entsha yale Blueprint bese uyifaka njengoxhumaniso ku-Blueprint yakho ukuze wabelane ngemali engenayo.
