FIREX RX 2373 modified epoxy binder
FIREX™ RX 2373 is a modified epoxy binder filled with thermally active materials that form cooling gases when exposed to temperature in excess of 350 ºF (177 ºC).  When heated to the range of 1000 - 5000 ºF (538 – 2760 ºC), a char forms that insulates by transpirational cooling and re-radiation. The filler materials act to efficiently control the release of gaseous molecular species. The material offers the same performance as FIREX™ RX 2390 and is appropriate for those applications needing a very smooth surface texture. All FIREX™ products adhere well to metals, wood, paper, and glass and readily accept a top coat.  FIREX™ RX 2373 is a two part epoxy resin system capable of application through screeding, trowel or injection molding. Pot life and cure time are adjustable with the addition of small amounts of solvent and the material cures at room temperature to a final density of 0.045 (1.245 g/cc). 

Over the years FIREX™ coatings have been utilized in numerous applications requiring fire and thermal protection. Those applications include ships, tanks, military vehicles, shelters, aircraft, and space vehicles and are especially protective in a jet fuel environment. Now they are available for chemical, oil and gas, and other applications.

Pyrogenics FIREX™
The Pyrogenics Group is a technological leader in the realm of specialized fire and thermal protection coatings. Pyrogenics FIREX™ coatings have provided fire and thermal protection for personnel and property for over 30 years.

FIREX™ coatings are used to "buy time" ... critical time... for the containment and suppression of thermal threats to personnel, equipment, and structures. Our intumescent or ablative FIREX™ coatings, absorb and reject thermal energy in a controlled and predictable manner and are primarily intended for use in high risk environments such as the oil, gas, petrochemical and power generation industries.

Our 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 type fires and hydrocarbon fires. These fires are caused by burning hydrocarbon fuels, such as petrol, diesel, petro chemicals and gases. These types of fires are characterized by a rapid and massive temperature increase as the fuel ignites that cause a high level of pressure (blast erosion), that typically destroys traditional thin-film intumescent coatings as well other typical structural steelwork fire protection.

FIREX™ coatings are used in numerous military and defense applications, including ships, tanks, military vehicles, as well as markets for agriculture, chemical, infrastructure such as buildings, airports, bridges, mining, oil and gas, power, pulp and paper, and waste industries.

In addition, we have teamed with the U.S. Army’s Aviation and Missile Research, Development, and Engineering Center (AMRDEC) to provide predictive modeling of applications based on our FIREX™ products which provide excellent test correlations. We can model the expected behavior of your application with our products and generate results to help guide your material selection process.

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.
