Intumescent Coating | Products Range | System E

Nullifire System E is a 2-part high performance epoxy intumescent coating specifically developed to protect structural steelwork, bulkheads and deckhead structures in the event of hydrocarbon fires.

Originally developed for the offshore and petrochemical industries, System E has been independently tested and certified to the highest standards:

  • Tested to the hydrocarbon curve for up to 4 hours
  • Tested to BS476: Part 20/21: 1987 for up to 3 hours
  • Blast tested up to 155kPa.
  • Tested to UL 1709 hydrocarbon test, which incorporates accelerated weathering
  • Lloyd’s certified
  • Jet fire test

HYDROCARBON FIRES
Hydrocarbon fires are caused by burning hydrocarbon fuels, such as petrol, diesel, petro-chemicals and gases. These types of fires are characterised by a rapid and massive temperature increase as the fuel ignites, which tends to drop away fairly quickly depending on the quantity of fuel involved.

This rapid increase in temperature also causes a high level of pressure (blast erosion), which would destroy traditional thin-film intumescents as well as most other typical structural steelwork fire protection.

By contrast, System E will withstand both the intense heat and pressure to ensure the bulkhead or structural steel work remains intact.

VERSATILE SYSTEMS WITH PROVEN PERFORMANCE
Nullifire System E Basecoat forms part of a complete 3-layer system consisting of :

Primer
To protect the steel against corrosion and prepare the surface. This provides a key for the application of the basecoat.

Basecoat
Applied to a measured thickness to provide the specified level of fire protection.

Top Seal
A hard decorative finish to seal in the basecoat and provide an attractive, high quality appearance.

PRIMER AND TOP SEAL COMPATIBILITY
It is vital that both the Primer and Top Seal are compatible with the Basecoat to ensure the integrity of the system in terms of fire performance and longevity.

A fully tested range of Nullifire Primers and decorative Top Seals is available. Please see:

In addition, Nullifire has tested and approved a range of general top seals and primer types for compatibility with System E Basecoat. It is vital to check over-coat periods and other relevant data with the coating manufacturer. It is advised that a primer and top seal compatibility check is carried out prior to application.

If you have any concern regarding the compatibility of specific primers or top seals with System S Basecoats, please contact Nullifire Technical Services Department.

APPLICATION
System E is applied using similar methods to those used for Nullifire’s traditional System S intumescents. Conventional airless manual or automated spray systems may be used. This coating may also be trowelled onto small areas of substrate.

System E provides a smooth hardwearing, impact resistant finish that can be coated with a range of decorative top seals. (See Primer and Top Seal compatibility above)
