What are the performance distinctions among various types of intumescent coatings (for example, water-based, solvent based, epoxies, methacrylates, etc.)?

From Bogdan Dana of WOOD GROUP INTEGRITY MANAGEMENT on September 24, 2012:
     Obviously, it will be the fire rating or how long a coating of a certain film build will resist (when applied on a certain type of substrate/structure) until the structure collapses under fire and this can be from 30 mins to 4 hours, based on a few factors: the binder type (acrylic or epoxy, both can be modified) and the intumescent system type (carbonific, esterifying agent and blowing agent; the ratio between these three components is also paramount). For both of these, the proportion is also crucial, as is the ratio between components and the ratio of binder plus intumescent system to the actual pigment/filler. (I carried out a study in the past where even the type of titanium dioxide pigment employed in an acrylic water- or solvent-based intumescent coating formulation made a difference in the fire rating.)
