Thermolysis of heat-insulating intumescent coating

Probably.

However,  they would need to understand the question first !  So - what exactly do you want to know ?

Mike.

I need to know the mechanism that describes the physicochemical nature of the process of thermolytic synthesis of intumescent coating on steel substrate or polymer substrate.

The mechanism that describes it will be words and diagrams.

The mechanism of producing the coating itself is probably not going to be thermolytic synthesis at all, for any current intumescent at least,  the common ones are all 3 of the normal methods for making paint, namely oil based, water based and epoxy based. Which one you reach for depends on the substrate and the environment it will be used in .

I ask again what exactly do you want to know ?

i.e.

What are you trying to achieve?

What is the problem to which you seek a solution?

Mike

Thank you Mike for a brief explanation

I would like to understand the mechanism of formulating inorganic heat-insulating coating that could be applied on polymer/steel substrate and the characteristics of charred heat-insulating layer on substrate due to diffusion and permeability of gases. I want to achieve the inoganic intumescent coating with high fire retardance.

you may find a read of a few patents on the topic helpful to get up to the state of the art.

I'd start with this one https://patents.justia.com/patent/10131800 as the intro is a good state of the art summary

Then  https://portal.unifiedpatents.com/patents/patent/US-4247435-A

Then https://data.epo.org/publication-server/rest/v1.2/patents/EP2093263NWB1/document.html

The most common approach is something that decomposes to  an acid, that then reacts with a carbonate or more recently a more complex organic,  as a blowing agent to create CO2 when hot, Then you need a second component, that in effect foams with the bubbles of CO2, and burns to  a char but does not disintegrate. This structure of frozen bubbles is a good insulator and protects the substrate it is formed upon.
