What you need to
know about intumescent paint India
We
can protect our steel structure from fire using intumescent paints which is
easy to apply off site and providing our steel a fine Matt finish. These
products are delivered on site fire protected and ready to use and install.
Let's
know about the purpose of an intumescent paint
Intumescentpaint India, also known as intumescent coatings or fire retardant or fire
proof paint are used in buildings as a passive fire resistance measure.
Furthermore, a thin film paint coating is preferable to boarding with fireproof
materials particularly if structural beams are to be left exposed. This coating
protects the steel for long time for fire fighters to make the building and
people who are inside safe. Also, the protection time usually between 30 to 60
mins but can be up to 2 hours.
How
intumescent paints work?
These
paints are applied with a brush and roller and look much like any other paint
coating when dry. In the event of fire, the paint coating reacts to high
temperature and swells by up to 100 times forming a hard char insulating the
structural steel members from any damage.
Different
types of intumescent paints?
There
are many different types intumescent paints both thin and thick Film are
available in the market. The thin ones are used as a fire protection system
while the thick ones are used in oil and gas industry. Furthermore, the thin
film intumescent paint can be either solvent based or water based. These day's,
new technologies have been developed and can provide fire resistance up to 2
hours.
Intumescent
paints will start to react and expand at 200° C temperature far below what
would cause damage to steel beam. Also, they form a hard carbonaceous char
which insulated the steel beneath from further increased in temperature as the
fire escalates. Usually, these paints used inside buildings where any major
corrosion protection is not needed. But these paints do approve a range of
primers for use with their intumescent coatings such as fast drying two pack epoxy
primers that provide good corrosion protection.
Intumescent paints usually Jotun paints are white but can be painted any colors with an approved topcoat. It is also vital to adhere to an approved paint system that is backed up by documents that you can show any inspector or building control. Furthermore, painting over an approved topcoat could need you remove all coatings and begin again. You can easily match colors with an approved topcoat.
