Formulated and manufactured to the highest standards, the Nullifire thin film intumescent coatings – specifically the SC900 series - offer application and performance advantages which have made it the first choice of builders, engineers, architects and specifiers in many countries world wide.

Combatting the effects of fire – with Nullifire

Fires are generally classified as either Cellulosic or Hydrocarbon fires. The essential difference between them relates to how quickly each reaches its maximum temperature range and the combustible fuel source feeding the fire.

Cellulosic fires are those that are fuelled by materials such as timber, furniture, paper, plastics and other common items as found in buildings such as offices, hospitals, shopping centres and residential buildings.

In such a fire, temperatures quickly reach around 550 degrees Celsius which over the course of the fire will have a dramatic effect on the structural steel within the building. Whilst it will not burn, it will warp and lose its ability to support a load, increasing the likelihood of building collapse.

Under the NCC all buildings with exposed structural steel are required to implement protective measures around the steel.

The Nullifire range of intumescent coatings are designed to protect structural steel in the case of cellulosic fire. Often called fire retardants, or mistakenly called "fireproof" paints, intumescent coatings refer to that class of specially formulated coatings which swell and form a protective "char" as a result of extreme heat exposure.

Nullifire intumescent basecoats are formulated specifically to fire protect structural steel up to a fire rating level of 120 minutes.
