In contrast, intumescents used
against hydrocarbon fires are epoxies.
Thin film is typically used in general
construction including structural steel,
while the thick-film coatings tend to
find use in the oil and gas industry,
such as for protecting petroleum re-
fineries. Depending on the application,
an array of low-VOC, (often) thick-
film chemistries can be used to achieve
specified requirements, such as the
ability to adhere to urethane foam.
Accordingly, Firetex M90/03, for ex-
ample, is a two-component, borate
free, 100 percent solids, anti-corrosive
epoxy fireproofing coating. “Designed
to thermally insulate both carbon steel
and galvanized steel during a hydro-

carbon pool fire, Firetex M90/03 is a
highly reinforced coating with superior
application characteristics and certified
performance properties,” Sherwin-
Williams says. “It is ideal for both on-
site and off-site applications, such as
in shops and in modular yards.”
Other top-line growth opportunities
cited for intumescent coatings include
applications requiring low smoke gen-
eration, combustion prevention, or as
a polymer for formulating thinner films
to improve aesthetics on steel surfaces.
Eliminating the need for a topcoat over
the intumescent product may also be
desired in some exterior applications.
Hilti Canada says its Fire Finish 120+
