Gay-Lussac notes
Early ammonium-phosphate fire chemistry on textiles.
Peinture intumescente · Peintures qui gonflent en charbon isolant : un R sur l’acier sans plaques épaisses.
Peinture intumescente did not arrive as a finished commodity. 1960s–70s commercial IFR; cellulosic vs hydrocarbon curves around US / UK / DE still explains who makes it and which tests it sits in.
Ten dated points, five eras and three milestones below are the spine — not a complete industrial history.
Early ammonium-phosphate fire chemistry on textiles.
Intumescent patents on wood.
Commercial steel coatings.
Fire-resistance furnaces for coated beams.
Offshore UL 1709 rapid-rise curves.
Low-VOC cellulosic coatings for offices.
Thin-film exposed steel fashion.
Not a cladding PE-core fix.
Dry-film thickness as a profession.
Topcoats decide whether the char still works in year 15.

Knowing this timeline is how to read a mill certificate without treating Peinture intumescente as timeless.
