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

Prices are bands. A 2024 coil is not a 2026 contract. Labour and certification often dwarf the commodity.
Producers listed are landmarks for orientation, not a ranking or a procurement list.
