FIRETEX FX9502 Cellulosic Fireproofing Coating

Sept. 8, 2021
Sherwin-Williams' FIRETEX FX9502 Cellulosic Fireproofing Coating combines lasting corrosion and fire protection with design possibilities.

The FIRETEX FX9502 Cellulosic Fireproofing Coating is giving building owners and architects fresh design flexibility, enhanced aesthetics, and long-term corrosion and fire protection. The 100% solids epoxy intumescent coating offers up to three hours of protection to structural steel in cellulosic fires to enhance safety for building occupants and first responders.


The epoxy formulation presents versatile design possibilities to showcase structural steel in both interior and exterior environments. The material allows architects to create complex building designs with exposed steel, compared to traditional designs that hide steel behind drywall and expensive decorative cladding to cover up unattractive cementitious fireproofing materials. The exposed, coated steel can be topcoated with a wide variety of protective coatings to further enhance its decorative appearance.


The ASTM E119-certified FIRETEX FX9502 is highly resistant to damage and wear, meeting UL2431 durability requirements for cyclic weathering, impact, vibration, salt spray resistance, and other key environmental factors. The coating can extend the life of assets in a range of environments from conditioned internal spaces to exterior heavy industrial applications without requiring a topcoat. With enhanced durability compared to acrylic intumescent coatings, it can better withstand the rigors of high contact spaces where people, objects, and equipment may impact coated columns.


For applicators, the coating offers some of the lowest competitive thicknesses in the ASTM E119 designs for fire ratings up to three hours and features a reduced total number of coats compared to acrylic intumescents. FIRETEX FX9502 can be applied either onsite or offsite.

With many fire ratings able to be achieved in as little as two coats when using FIRETEX FX9502, steel can be fire protected in just one working day. In addition, the coating’s typical overnight dry-to-handle times enable fully fire protected steel to be quickly transported from the paint shop or on-site application area to the construction site.


Further enabling efficiencies for applicators, FIRETEX FX9502 has excellent sag resistance and can be applied at a high film build with minimal finishing requirements. For added flexibility, it can also be applied via trowel, single-leg airless or plural-component methods.


FIRETEX FX9502 can be specified for a wide array of public buildings and structures, including hotels, convention centers, atriums, bridges, airports, transportation terminals, schools, and gymnasiums. Its durability also makes it ideal for use in parking garages, warehouses, and heavy-duty manufacturing facilities.
