Nullifire is a market leader for intumescent coatings and has pioneered the use
of this technology on a global basis for over twenty years. Whether the
substrate is structural steelwork or timber, in the form of panels or beams, the
use of thin film fire rated coatings allows the designer and specifier to
produce structures that are aesthetically pleasing and to maximise the available
space.
This is achieved through the provision of high performance intumescent coatings.
These coatings take up very little space compared to other forms of passive fire
protection and offer a number of other benefits in terms of:
 | Their high quality finish, akin to a conventional decorative paint system
| The ability to overcoat the active intumescent layer in a decorative
topseal in RAL and British Standard colours
| The surfaces lend themselves to applications where the ability to clean
the surfaces is paramount.
The fact that the required level of fire protection to the building
structure may be achieved using a relatively thin high performance coating
means that the weight of the fire protection is kept to a minimum which, in
turn, allows greater spans to be achieved. This is of key importance when
designing large bay warehousing and sports stadia, for example.
The Nullifire range of intumescent coatings fall into three main
categories:
 | Thin film coatings (System S range), for use in commercial and light
industrial applications
| Heavy-duty epoxy based intumescent systems (System E range) for use in
more severe environments, where abrasion may be a factor and where the
ability to withstand hydrocarbon fires is a requirement
| The System W range of intumescent coatings for timber, often used, not
only in new construction, but also to renovate historical buildings
where there is a desire not only to preserve the original appearance of
the structure, but also to bring it up to standards with prevailing
building regulations. The coatings for timber paneling and structural
elements are used, where either a clear coating is required to feature
the natural finish of the timber, or a pigmented version is used to seal
the timber, and again, where it is necessary to achieve a specified
degree of surface spread of flame and erosion rate of the structural
element in a fire.
The intumescent coatings used to protect structural steelwork are
typically less than 2mm in thickness when applied and cured on the
steelwork. When exposed to a fire, a series of chemical reactions occurs
within the chemical thickness, causing a carbonaceous or meringue-like
char to form. This char will then solidify, having a depth of up to 80mm
which reflects heat and restricts the build up of the steel substrate
within its structural fire performance limits for a specified period of
time. The development and technology of intumescent coatings is an
ongoing process and the systems available today are based on either
solvent or water-borne chemistry, which allows the Nullifire range to
satisfy the building regulations both in the United Kingdom and in many
countries around the world.
