- X is independently selected at each occurrence from chloro, alkoxy, acyloxy and oximino;
- R is a hydrocarbyl group;
- and
- (d) a compound providing an expansion gas upon thermal decomposition wherein such compound comprises melamine;
- wherein the compounds as defined for (a) to (d) differ from each other, wherein the intumescent coating composition is liquid at 23° C. and atmospheric pressure and comprises less than 5 wt.-% water based on the total weight of the composition.
