A Guide to Nullifire Intumescent Coatings System


For decades Nullifire has been one of the leading innovators of steel protection and intumescent coatings.

Intumescent coatings protect steel from reaching structural failure temperatures and with steel protection from Nullifire these will maintain structural stability for up to 120 minutes, giving the emergency services time to evacuate people from the structure and stop the fire.

Our products have been exhaustively tested both in our own laboratories but also to national and international standards in independent test houses across the globe, offering the ability to match a number of requirements. 

Engineered for compatibility, Nullifire intumescent coatings range includes basecoat, primers and top seals - a complete system for fire protection and decoration of structural steel.

Simply hover over your selected coating build, to see what products we would recommend for install.

Nullifire's Complete System

The SC ranges...

Water-Based Intumescent Coatings (SC800 range)

Nullifire pioneered water-based technology, which gives a smooth finish in a faster time than other methods. Given the environmental benefits of water-based coatings then these products are now the preferred choice among specifiers and applicators alike.

Solvent-Based Intumescent Coatings (SC600 range)

For when environments are semi-exposed then solvent based products still provide an answer in obtaining an excellent finish in a reasonable time frame.

Hybrid Intumescent Coatings (SC900 range)

These unique technologies have been developed to provide faster cure times without multiple coats, while still delivering the same level of fire protection and ratings. These are only available through Nullifire's approved applicators.

The PM range...

For primers that work in harmony with protective intumescent coatings then look no further than these recommended solutions from Nullifire.

All of these have been tested to enable them to be specified together with the confidence that they will perform both in application and in the event of fire.

The TS range...

Top Seals are the final element, designed to make the finished steel work look good, but also to protect the intumescent basecoat underneath.

Always make sure that the top seal is compatible with the basecoat by selecting from the Nullifire range.
