Enhanced durability verified by doubling UL 2431 conditioning environment exposures, without topcoat
Verification Method
To demonstrate enhanced durability of PPG PITT-CHAR® NX epoxy intumescent passive fire protection coating, the product was subjected to a double exposure of the exposure conditions required for Classification Category I-A, specified for Outdoor, Heavy Industrial applications as described in UL 2431, Standard for Safety for Durability of Fire Resistive Coatings and Materials. The exposure conditions include air erosion (double air-erosion test cycles), a combination of wet, freeze and dry cycling (double duration), impact resistance (double impact test cycles), industrial atmosphere (double duration), salt spray (double duration), a combination of temperature stability, ultraviolet light and high humidity cycling (double duration), and vibration (double vibration test cycles). After the double exposure, the test specimens were then fire tested against control samples under the hydrocarbon fire test curve defined in UL 1709 Rapid Rise Fire Tests of Protection Materials for Structural Steel and the results complied with the requirements of the standard for this classification category.
