Intumescent Coatings for architectural design flexibility

Traditionally buildings have been designed with a frame made of concrete beams and columns. While this is a low cost method of building it is slow to erect and limits the design capability.

Many of the world’s leading architects are now designing with structural steel allowing them to express modern ideas and shapes with exposed features and open atriums.

Nullifire has pioneered the use of thin film intumescent coatings on these steel structures.
Intumescent coatings offer the ability to fire protect the steelwork while enhancing its aesthetic appearance.

Fire ratings up to 2 hours are possible on many types of steel sections for both interior and exterior steelwork.
By combining Carboline primers and topcoats with Nullifire intumescent coatings a fully compatible system can be designed to meet the specific needs of any project.

Nullifire intumescent coatings can be applied by airless spray either on site after the steel is erected or off site in the fabrication shop prior to the shipment to site.

Project planners and designers now have the flexibility to use Nullifire intumescent coatings to improve the constructability of major projects.

In aggressive environments or extreme conditions where normal fire protection products are not suitable we can offer Nullifire System “E” Epoxy Intumescent.

This a high performance product that has been tested to UL 1709 for long term durability.

It can provide up to 4 hours fire protection in hydrocarbon fires. Typical applications include oil and gas platforms, petrochemical facilities and critical assemblies in the aerospace industries.



Pyrocrete and Pyrolite for industrial fire protection. Carboline product offer a level of unparalleled performance proving longer protection than any other proprietary cementitous fire proofing material on the market.

Pyrocrete 241 has been the industry leaders for over 25 years and is the most widely specified fireproofing product in the industry today.

Pyrocrete 240 High Yield and Pyrocrete 40 over the same level of fire resistance at a more competitive price. Pyrocrete products are hard, durable and impact resistant.
