MINTEQ® Firex™ intumescent fire retardant coatings have provided fire and thermal protection for personnel and property for over 30 years.

Complying with stringent military and defense fire standards, Firex™ products have a proven track record and are optimized to provide the highest level of performance in rapid temperature rise fires, retaining strength, with excellent adhesion even in the harshest of environments such as cellulosic and hydrocarbon fires.

Function of Flame Retardants
Firex™ coatings are designed to interrupt or hinder the combustion processes of a fire allowing more time to escape.

Our coatings delay or slow:

• time to ignition (flash over)
• smoke development
• spread of flames
• release of toxic gases
• release of corrosive chemicals
• release of heat

Firex™ fire retardants interfere with the combustion at various stages of the process including during heating, decomposition, ignition or flame spread.

How Does Firex™ Work?
Firex™ coatings are designed to

• promote the formation of char layer
• create a glassy protective layer
• terminate free radical processes in the gaseous phase
• cool the coating down through heat absorbing reactions - e.g. by releasing cooling gases

Coating Thickness
Firex™ coatings coating thickness varies based on the substrate and the desired protection time.

For example, to adequately protect structural steel the coating thickness depends on the size of the steel member, its orientation, and the desired protection time.

For most fire protection requirement an hour protection rating is achieved with about 13 to 19 mm thickness. Each coat is generally about

1.5 mm and build up over time.

Product Offerings:

FIREX™ RX-2373
FIREX RX 2373 is modified epoxy binder filled with thermally active materials that form cooling gases when exposed to temperatures in excess of 350°F (177 °C). When heat in the range of 1000 to 5000° F (538 to 2760°C) is applied, a char forms which insulates by transpirational cooling and re-radiation. In addition, filler materials more efficiently control the release of gaseous molecular species.

After partial use, the char is brushed away and the FIREX™ RX-2373 re-useable or refurbished with additional material. Adhesion to metals, wood, paper, and glass is excellent; it readily accepts a top coat.

FIREX™ RX-2373 is furnished solvent-free as "A" and "B" components with a shelf life of six months. When thoroughly mixed, the material is applied by spreading or troweling and by injection mold. Pot life and cure time is adjustable for a variety of applications by the addition of small amounts of solvent. RX-2373 cures at room temperature with a final density of 0.045 lb/in3 (1.245 g/cc).

FIREX™ RX-2390
FIREX RX 2390 is modified epoxy binder filled with thermally active materials that form cooling gases when exposed to temperatures in excess of 350° F (177 °C). Then heat in the approximate range of 1000 to 5000° F (538 to 2760°C) is applied, a char forms which insulates by transpirational cooling and re-radiation. In addition, filler materials more efficiently control the release of gaseous molecular species.

After partial use, the char is brushed away and the FIREX™ RX-2373 re-useable or refurbished with additional material. Adhesion to metals, wood, paper, and glass is excellent; it readily accepts a top coat.

FIREX™ RX-2390 is a two-part epoxy resin system. It is produced in sprayable and trowelable versions, with a shelf life of six months, as well as precured panels, this material is used on vertical surfaces without sagging or slumping. Coating thickness up to 60 mils (15 µm) can be applied in a single pass. RX-2390 cures at room temperature, with a final density 0.045 lb/in3 (1.245 g/cc).

FIREX™ RX-2376
FIREX RX 2376 is a polyurethane based coating containing active fillers that form a liquid film at temperatures of 250° F (121 °C) or higher. Under conditions of aerodynamic heating, this film is swept away by the air stream without affecting airfoil characteristics and electrical transmission. As long as unreacted material remains, the substrate temperature will remain at approximately 250° F (121 °C).

Application of FIREX™ RX-2376
FIREX™ RX-2376 is a two component liquid system that is mixed in the ration of 100 parts component A to 172.5 parts component B. Pot life is approximately one hour at room temperature. Application of the material is done with conventional suction type paint spray equipment after mixing. Application of the material is universal on all surfaces but horizontal orientation maximizes uniformity and a smooth surface coating.

A maximum thickness of twenty to thirty mils can be applied at one time. For applications requiring thicker coatings, twenty to thirty mils should be applied per pass and a six hour drying time allowed between passes. Cure time is twenty-four hours. Cured materials remain stable at temperatures from -65° F to + 200° F (- 54 to + 121°C).

FIREX™ RX-2376 has a limited shelf life characteristic of many polyurethane based materials. As long as the containers are kept tightly sealed, shelf life is at minimum 30 days at ambient temperature and as long as 90 days under refrigeration.
