Quick answers

Is Intumescent coating non-combustible?

Declared reaction class in this atlas: coating on A1 steel; system tested. Assemblies still need resistance tests.

Does Intumescent coating insulate?

Thermal mark 70/100 versus the atlas. Conductivity note: char foam becomes the insulator.

What is the density band?

wet film as specified

How is it made?

Origin story: 1960s–70s commercial IFR; cellulosic vs hydrocarbon curves (US / UK / DE).

Can it be recycled?

Circularity mark 42/100 — editorial, route-specific.

Typical melting or failure heat?

designed to foam ~200–300 °C

heat 60 · fire 88

Start with this section - Origins & milestones

Intumescent coating 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.
