-Intumescent coatings work as follows:
The thermoplastic binder melts upon exposure to the heat of the fire to allow further chemical reactions to take place in the softened matrix.
The acid donor (often a salt of polyphosphate) decomposes to form polyphosphoric acid.

The Polyphosphoric acid reacts with Charmor PM40 to form polyphosphoric acid esters.
The esters decompose to form a foamable carbon matrix.

The blowing agent (often melamine) releases gases that cause the carbon matrix to create a foam that hardens to form a tough insulating char barrier that adheres to the substrate.

Charmor PM40 is particularly suitable for waterborne and solvent-borne intumescent coatings.
The particle size of the Charmor PM40 product used has an impact on the nature of the foam.
Smaller particle sizes yield thicker char foam.
