Gay-Lussac notes
Early ammonium-phosphate fire chemistry on textiles.
膨胀型涂料 · 遇火膨胀成隔热炭层的油漆——不用厚板也能给钢材R等级的薄层。
膨胀型涂料 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 膨胀型涂料 as timeless.
