Intumescent coating is one of 32 materials in this atlas, grouped under fire: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.
Scores compare Intumescent coating with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.
Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.
Deep introduction
Deep dive: Intumescent coating
Intumescent coating (acid source + carbon + spumific (typical APP/PER/MEL)) is a family of grades whose density wet film as specified, heat band designed to foam ~200–300 °C, and fire letter coating on A1 steel; system tested.
What “the material” actually is
Intumescent coating is sold as grades, not as a single substance. Chemistry acid source + carbon + spumific (typical APP/PER/MEL), density wet film as specified, heat band designed to foam ~200–300 °C.
This atlas treats Intumescent coating as a system: mill route, coatings, tests and the cavity it sits in.
Heat, fire and insulation
Conductivity note: char foam becomes the insulator. Insulation score 70/100 is relative to 32 entries — metals lose, VIPs and aerogels win.
Fire letter in editorial use: coating on A1 steel; system tested. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
How it is made and used
Origin: 1960s–70s commercial IFR; cellulosic vs hydrocarbon curves, US / UK / DE. The process chapter follows feedstock → conversion → forming → finish → install.
Uses span buildings to defence / safety. Pairings matter: steel.
Market and circularity
Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.
Circularity mark 42/100. Ask which scrap, which certificate, which year.

Decision walkthrough on Intumescent coating: fire 88, insulation 70, and one fact already on file — not a code stamp.
Read the fire-performance mark — Fire on this hub is 88/100 — teaching comparison among atlas materials.
Read the insulation mark — Insulation is 70/100 — heat-flow story, not the same question as flame.
Sit one published fact beside them — Quick fact on file: Job: Swell to char.
Sustainability is not a fire skip — A high sustainability mark does not replace fire protection in a real assembly.
Not a building-code rating — Named tests, thickness and build-up still decide compliance — this page is literacy only.
On Intumescent coating, fire 88 and insulation 70 answer different jobs; Job: Swell to char grounds one real detail.
Editorial atlas marks. Not a code certificate or product approval.
Thermal mark or safety fact first?
Second lab decision on Intumescent coating: heat-resistance 60 beside published thermal fact Conductivity — literacy, not a code stamp.
Read the heat-resistance mark — Heat resistance on this hub is 60/100 — a thermal story, different from the fire/insulation pair.
Sit one thermal fact beside it — Properties chapter lists Conductivity among published thermal rows.
Heat resistance is not a fire skip — A high thermal mark does not replace named fire tests in a real assembly.
Still not a building-code rating — Thickness, build-up and named tests decide compliance — this page teaches axes only.
On Intumescent coating, heat 60 and Conductivity are a second thermal/safety reading after fire vs insulation.

Frequently asked questions
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
What should it be paired with?
steel: The substrate that needs the char.
Where is it specified?
Buildings, transport, energy and consumer goods — see the uses chapter.
Is the fire-performance score a building-code rating?
No. It is an editorial 0–100 teaching mark among materials in this atlas. A real wall or garment needs a named product test, thickness and assembly. This page is not a lab stamp.
When should I read insulation instead of fire?
Use the insulation pick when the question is heat flow — lining, loft, or a cold-bridge — and the fire pick when the question is how the same material behaves in flame. Both numbers already sit on this hub; they answer different jobs.
Does a high sustainability score mean I can skip fire protection?
No. Sustainability here is a relative atlas mark (growth, reuse, embodied story). Bamboo and timber can still char like wood. Fire protection stays a separate specification.
Why is bamboo missing in some languages?
A language URL is published only when the seven chapters are real prose in that language. Bamboo exists in English, Korean, Japanese, Chinese and Spanish. French, German, Portuguese and Russian stay withheld — earlier machine drafts leaked English, so those URLs are not opened.
