Firetex FX2008 Intumescent Coating

Firetex FX2008 Intumescent Coating Overview

Firetex FX2008 is a single pack, solvent-based thin film intumescent coating formulated to provide up to 120 minutes of fire resistance to structural steel. Designed for efficient in-shop airless spray application, it delivers high film build, rapid drying characteristics, and dependable passive fire protection performance.

Firetex FX2008 Solvent Based Intumescent Coating

Firetex FX2008 is engineered to protect structural steelwork by forming an insulating char layer when exposed to high temperatures. This reaction slows the rate at which steel reaches critical failure temperatures, helping to maintain structural integrity during a fire event.

Developed for fabrication shop environments, FX2008 offers a high solids formulation that allows substantial dry film thicknesses to be achieved in fewer coats, supporting productivity and programme efficiency. Supplied in white, the coating can be left un-topcoated in certain dry, internal environments or overcoated where enhanced durability, weather resistance, or decorative appearance is required.

Applications & Uses

Firetex FX2008 is specifically designed for in-shop application by airless spray to structural steel, providing fire resistance for up to 120 minutes. It is suitable for beams, columns, cellular sections, and complex fabricated steelwork across commercial buildings, industrial facilities, warehouses, transport hubs, and infrastructure projects.

After appropriate drying, the coating can resist normal weather exposure for up to six months without a topcoat, provided that exposure does not result in ponding water from rainfall or condensation. This flexibility supports phased construction programmes where steel may be erected prior to final finishing.

For externally exposed steelwork and severe internal environments, approved polyurethane topcoats should be applied to deliver long-term durability and environmental protection. For other internal areas where a decorative or protective finish is required, compatible topcoats can be specified.

Preparation

Firetex FX2008 is intended for application over suitably prepared and primed substrates. All surfaces must be clean, dry, and free from oil, grease, dust, mill scale, and corrosion products to ensure proper adhesion and performance.

In certain controlled circumstances, the coating may be applied directly to steel that has been blast cleaned to a high standard with an appropriate surface profile. For most in-shop systems, the use of a compatible blast primer is recommended to optimise adhesion and corrosion resistance beneath the intumescent layer.

Application should preferably be carried out at temperatures above 5°C. The substrate temperature must be at least 3°C above the dew point and always above 0°C. Adequate ventilation is essential, particularly in conditions of high relative humidity, to ensure correct film formation and curing.

Application

Airless spray is the recommended method of application, allowing high-build coats to be applied efficiently and consistently. Suitable heavy-duty spray equipment with appropriate tip sizes and pressure settings should be used to achieve optimal atomisation.

A typical spray-applied coat can achieve substantial dry film thickness in a single application, reducing the number of passes required. No more than two coats should be applied within a 24-hour period. Exceeding the recommended thickness per coat or overcoating prematurely may result in surface cracking.

The coating must be protected from moisture during the drying period, as premature exposure to rain or condensation may affect its integrity and fire protection performance.

Drying & Curing

Drying times will vary depending on film thickness, temperature, humidity, and air movement. Under normal conditions, the coating becomes touch dry relatively quickly, with recoating possible after several hours.

For temporary external exposure without a topcoat, sufficient drying time must be allowed in dry, well-ventilated conditions. Thicker film builds or lower temperatures will extend curing times.

The maximum service temperature is 70°C. At elevated temperatures above approximately 40°C, some thermoplastic characteristics may be observed.

Safety Information

As a solvent-based coating with a low flash point, Firetex FX2008 must be handled with care. Always follow safe working practices, use appropriate personal protective equipment, and ensure adequate ventilation during storage and application.

Store in tightly sealed containers in a cool, dry area away from heat and ignition sources. Proper storage will help maintain product performance throughout its shelf life.
